MSI Afterburner - Changelog

Changelog Version 4.6.6 Beta

• Ported to VC++ 2022 compiler. Please take a note that due to this change MSI Afterburner will no longer be able to start under Windows XP. Please stay on the previous versions of the product if you need this OS support
• Please take a note that size of mandatory VC++ 2022 runtime redistributables roughly doubled comparing to the previously used VC++ 2008 redistributables, and we'd like to avoid providing overblown application distributive, drastically increased in size due to bundling newer and much heavier VC++ redistributables with it. To deal with this issue we provide our own original tiny web installer for VC++ redistributables, which allowed decreasing the size of final application distributive drastically even comparing to the previous VC++ 2008 based version. Please take a note that install time can be increased slightly due to downloading VC++ 2022 runtimes redistributables on the fly during installation. If you install MSI Afterburner offline, you can always deploy required VC++ 2022 distributives later with web installer by launching .\Redist\VCRedistDeploy.bat
• Added voltage control support for AMD RADEON RX 7800XT series graphics cards
• Added some future NVIDIA GPU PCI DeviceIDs to hardware database
• Now MSI Afterburner reinitializes skin scaling engine on DPI scaling change events to prevent cases when GUI looks cut off in some cases (e.g. after switching between display resolutions with different DPI scaling settings)
• Fixed instances enumeration for some performance counters with no localized names (e.g. GPU related Windows performance counters) in PerfCounter.dll plugin
• Added experimental support for "Beta : Use Unicode UTF-8 for global language support" option enabled in administrative regional OS settings. Now each localization description file contains additional "Codepage" field, defining runtime ANSI to UTF8 conversion rule for selected language pack

Changelog Version 4.6.3 Final

• Added NVIDIA Ampere GPU architecture support:
  • Added new fan control 3.0 API support
  • Added new integrated OC Scanner API support, please read below to get more information about new OC Scanner implementation
• Updated bundled MSI Overclocking Scanner application:
  • Starting from 455.xx drivers family, NVIDIA OS Scanner is no longer implemented as a separate software component redistributed with each AIC partner's overclocking software. Now NVIDIA OC Scanner is integrated into the driver and third-party software can natively access it via NVAPI. Such implementation simplifies the process of OC Scanner maintenance for NVIDIA, it is no longer necessary to ship updated software components to AIC partners and re-release each partners' software when something needs to be changed inside OC Scanner from NVIDIA side. MSI Overclocking Scanner supports both implementations of NVIDIA OC Scanner API:
• Old legacy implementation of NVIDIA OC Scanner via separate software components for NVIDIA Pascal and Turing architectures for pre-455.xx drivers family
• New integrated NVAPI based implementation of NVIDIA OC Scanner for 455.xx and newer NVIDIA display
• drivers
• New NVAPI based OC scanner implementation features the following changes and improvements:
  • Automated overlocking support for both core and memory clocks
  • OC Scanners's results are now persistent. It means that once the scanning process succeeds, NVIDIA driver internally saves optimized voltage/frequency curve and overclocked memory clock and apply them as new system defaults after reboot, even if you close or uninstall overclocking application. Now there is new "Revert" button inside MSI Overclocking Scanner, which allows you to revert overclocked curve and memory clocks to their real defaults
  • Manually adjusted clock/frequency curve stability testing functionality is deprecated and no longer available
• Added voltage control for reference design NVIDIA GeForce RTX 30x0 series graphic cards
• Added new MSI Ampere and Indigo skins by Drerex design
• Added experimental support for Intel 10th generation CPUs

• Added workaround for AMD driver bug causing short display flicker during applying new fan settings on some multi-monitor or single monitor high refresh rate display configurations
• Now MSI Afterburner is forcibly disabling Zero RPM when applying new fixed fan speed in order to bypass AMD driver bug
• preventing fan control from working when Zero RPM mode is enabled on some systems. If Zero RPM is working properly on your system and you still want to keep it enabled when adjusting fan speed, you may disable forcible Zero RPM override with power oriented switch in application configuration file ow MSI Afterburner is displaying the minimum allowed fan speed in software fan curve editor window on Overdrive 8 capable AMD GPUs. The latest AMD drivers will not allow you to set fan speed below this limit, that's by design of driver AMD ADL components are loaded by absolute path now to prevent possible DLL hijacking.
• Tightened IO driver access policy, the driver can no longer be accessed by users with no administrative rights RivaTuner Statistics Server has been upgraded to v7.3.0. This version introduces plugins architecture and brand new visual overlay editor plugin, we strongly recommend you to try it if you're advanced user and want to customize your OSD beyond the possibilities of MSI Afterburner's internal OSD layout editor.
• MSI Afterburner 4.6.3 beta 5 will additionally contain one minor functionality upgrade for AMD 6800/6900 users: now it internally switches "Tuning control" to "Manual" mode automatically, so it is not necessary to do it yourself in Adrenalin control panel. And of course, it will contain updated RTSS 7.3.0 Beta 10 bundled with it.

Changelog Version 4.6.2

• Added voltage control for reference design NVIDIA GeForce RTX 20x0 SUPER series graphic cards
• Added voltage control for AMD RADEON RX 5700 series graphics cards
• Added new MSI Steampunked, MSI Lightning Anniversary and MSI Mystic skins by Drerex design
• Improved hardware monitoring module:
  • Added CPU temperature monitoring support for AMD Ryzen 3X00 processors family
  • Added thermal offset for CPU temperature monitoring on AMD Ryzen Threadripper 29X0 processors family
  • Added package CPU power and per-core CPU power monitoring for AMD Ryzen processors family
  • Improved monitoring plugins architecture:
• Added API function for reading host application's hardware monitoring timestamp from the plugins. The timestamp is updated by host on each hardware polling iteration, so it allows the plugin to precache and reuse some sensor data if the same physical sensor value is being used in multiple data sources exported by plugin. Such approach is demonstrated in updated CPU.dll plugin for duplicating the same temperature sensor value for all cores on AMD CPU
• Added optional plugin unititialization callback function, which is called by the host before unloading the plugins. New multithreaded Ping.dll plugin is demonstrating new function usage to shut down ping monitoring thread properly
• Improved monitoring plugins:
  • Updated CPU.dll plugin is demonstating AMD Ryzen CPU temperature monitoring implementation and optimal duplication of the same temperature sensor readback for all CPU cores
  • Added new Ping.dll plugin for monitoring ping to desired server via ICMP echo requests. Please take a note that the plugin is configured to monitor ping to www.guru3d.com by default, it is up to you to specify target server name or IP address in the plugin properties
• Improved skin engine:
  • Optimized skin rendering performance for skins using multiple overlapped animated indicators
  • Added position smoothing support to skinned indicators
  • Now skinned applications can forcibly disable indicator animation if necessary
  • Skin format reference guide has been updated to v1.8 to document these changes
• Updated IO driver provides more secure MMIO and MSR access interface
• RivaTuner Statistics Server has been upgraded to v7.2.3
• Added new MSI Steampunked skin by Drerex design
• Improved skin engine:
  • Optimized skin rendering performance for skins using multiple overlapped animated indicators
  • Added position smoothing support to skinned indicators
  • Now skinned applications can forcibly disable indicator animation if necessary
  • Skin format reference guide has been updated to v1.8 to document these changes

Notes on Animated Steampunk Skin - 4.6.2 is optimized to improve performance of background animation rendering of new Steampunked skin, however, skin animation can still be rather performance hungry on old slow CPUs. So keep your eyes on CPU usage when using this skin, and if it is too high for you, you may try to do the following things to reduce it:

• Set skin composition mode to "layered with colorkey" (the fastest one) if you were using "layered with alpha" mode. Layered skin composition mode with alpha channel is the slowest one and the most CPU hungry due to using per-pixel transparency
• Reduce skin scaling factor in UI properties of MSI AB, higher skin scaling values cause higher CPU load
• Disable animation completely, currently there is no dedicated option for it in GUI, however you can do it via editing the config and setting EnableAnimatedIndicators to 0

Changelog Version 4.6.1

• Added new MSI Touch of Modern skin by Drerex design
• Added asynchronous dual fan control support for reference design NVIDIA GeForce RTX 20x0 series graphics cards. Please take a note that only 100% NVIDIA reference design dual fan control implementations are supported, third party proprietary asynchronous fan control solutions (e.g. EVGA iCX series asynchronous fans) are not supported and will not be supported in future versions. The following asynchronous fan control functionality is available:
  • Added new "Synchronize fan speeds" button, which is allowing you to switch between synchronous and asynchronours fan control modes. Please take a note that new fan speed controls are available in v4 skins only, v3 and v2 skins are deprecated and no longer receive new functionality
  • When fan speeds synchronization is enabled, MSI Afterburner's fan control functionality behaves exactly like in the previous version, i.e. both fans are running asynchronically in default hardware automatic fan speed control mode but become linked synchronically if you enable manual or software automatic fan speed control mode
  • When fan speeds synchronization is disabled, you may select and adjust each fan speed independently. For software automatic fan speed control mode independent temperature curves are also adjustable for each fan
• Improved hardware monitoring module:
  • Inverted hotkeys handling approach for multiple selected hardware monitoring graphs. Previously single graph settings mode was active by default, but you could apply some settings (e.g. "Show in On-Screen Display") to multiple selected graphs with <Ctrl> hotkey modifier. Now such settings are applied to multiple selected graphs by default and <Ctrl> hotkey modifier is used to apply settings to single focused graph
  • Group operation notifier has been moved to hardware monitoring graph properties header
  • Improved backward compatibility with monitoring profiles created in the previous versions of application. It is no longer necessary to recreate the profiles having monitoring settings without On-Screen Display layout
  • It is no longer necessary to click <Apply> button inside the On-Screen Display layout editor after changing current layout, now the changes are applied properly on closing the editor
  • The progress of saving multiple graphs' settings is now displayed in the caption of the application's property sheet
  • Optimized handling of "dirty" flag for settings decreases saving time for multiple graph's settings when using multiple subsequent group operations
  • Added new "Hide attached monitoring panel" command to the context menu of hardware monitoring window. You may use it to toggle visibility of monitoring window when it is attached to the main application window
  • Now you may press <Ctrl> + <M> hotkeys to toggle monitoring window attachment
• Improved voltage/frequency curve editor for both AMD and NVIDIA GPUs:
  • Now you may hold <Shift>and press left mouse button on initial desired horizontal position in the editor window to begin fragment selection, then drag mouse cursor to desired final horizontal position and release left mouse button to select a fragment. The following functionality is available for selected fragments:
    • You may double click the editor window to reset fragment selection
    • You may adjust the offset for any point inside the selection with mouse cursor to apply the same offset simultaneously to all selected points
    • You may adjust the offset for any point inside the selection with keyboard cursor keys, <Enter> or <Shift>+<Enter> keys to apply the same offset or specify the same target frequency or voltage for all selected points
• Improved skin engine:
  • Skin engine no longer crashes when switching between the skins having the same site with and without alpha channel
  • Added thumbless skinned slider controls support
  • Added alpha path threshold support for skinned slider controls
• Improved skin cross-compatibility layer:
  • Extended list of applications supported by skin cross-compatibility layer
  • Various compatibility fixes for third party skins supported by cross-compatibility layer
  • Fixed issue with GUI stopping responding during adjusting skin scaling ratio on the fly in high DPI mode when skin composition mode was set to layered mode with alpha
• Updated third party hardware database:
  • Added new third party voltage control capable graphics cards to the database
  • Added new third party graphics cards with multichannel GPU, memory and VRM temperature sensors to the database

Changelog Version 4.6.0
- Added NVIDIA Turing GPU architecture support:
o Added voltage control for reference design NVIDIA GeForce RTX 20x0 series graphics cards
o Advanced GPU Boost control for NVIDIA GeForce RTX 20x0 series graphics cards. Extended voltage/frequency curve editor on GeForce RTX 20x0 family graphics cards allows you to tune additional piecewise power/frequency floor and temperature/frequency floor curves. Control points on those new curves allow you to control GPU Boost power and thermal throttling algorithms more precisely than traditional power limit and thermal limit sliders
o Hardware abstraction layer has been revamped to provide support for multiple independent fans per GPU due to introducing dual fan design on reference design NVIDIA GeForce RTX 20x0 series graphics cards and due to introducing native dual fan control in NVAPI. Both fans of NVIDIA GeForce RTX 20x0 can be monitored independently in hardware monitoring module now and can be controlled synchronically in manual mode
o Added NVIDIA Scanner technology support
- Added Monolithic Power Systems MP2884A and MP2888A voltage controllers support
- Added core, memory, auxiliary PEXVDD and auxiliary 1V8 voltage control for custom design MSI RTX 2080Ti Lightning series graphics cards with MP2888A + MP2884A +uP1816 voltage regulators
- Added VRM and VRM2 temperature monitoring for custom design MSI RTX 2080Ti Lightning series graphics cards
- Added AMD Vega 20 GPU architecture support:
o Added Overdrive 8 technology support for AMD RADEON VII series graphics cards
o Added extended thermal monitoring for RADEON VII series graphics cards. Extended thermal monitoring includes dual-channel GPU temperature monitoring (edge and junction temperatures), memory temperature monitoring and quad-channel VRM temperature monitoring (core, SOC and two memory VRM temperatures)
o GPU usage monitoring filtering algorithms are reenabled for AMD ADL based GPU usage monitoring implementation to minimize fluctuations in monitored GPU usage on AMD RADEON VII series graphics cards. Please take a note that filtering algorithms make GPU usage graph more inert and smooth, so you may disable them via configuration file if necessary
- Added fan control support for AMD Adrenalin 2019 drivers family. Please take a note that AMD Adrenalin 2019 drivers adjust fan speed in PWM duty cycle mode but fan speed monitoring is provided in RPM only, which means that you cannot read back exact programmed fan speed in percents. Due to this limitation, MSI Afterburner is reporting fan speed as percent of maximum RPM instead of real fan duty cycle when default AMD auto fan control is in use. So monitored fan speed can slightly mismatch programmed fan speed curve if you're using default AMD automatic fan control
- Added new MSI Gaming Z skin by Drerex Design
- Improved hardware monitoring module:
o Added thermal offset for CPU temperature monitoring on AMD Ryzen 7 2700X processors
o Similar CPU temperatures are now cloned for all cores on AMD CPUs to provide more convenient and unified On-Screen Display layout between Intel and AMD CPUs
o "Pagefile usage" graph in hardware monitoring module has been renamed to "Commit charge"
o Added group operation notifier to the caption of active hardware monitoring graphs list in "Monitoring" tab in the application properties. The notifier is informing you that you can apply a setting to all or to multiple selected hardware monitoring graphs when you hold group operation key (i.e. <Shift> or <Ctrl>) and hover mouse cursor over the setting that can be applied to multiple hardware monitoring graphs at once (e.g. "Show in On-Screen Display")
o Added "Select by group" and "Select by type" commands to context menu of active hardware monitoring graphs list in "Monitoring" tab in the application properties. New commands allow selecting the graphs of exactly the same type (e.g. CPU1-CPU8 usage graphs on eight core CPU) or the graphs with the same OSD/LCD group name (for example, GPU clock, GPU power, GPU usage and the rest graphs with "GPU" group name). Such commands allow you to show similar items (e.g. all CPU usages) in On-Screen Display with a single click or rename a group for all child graphs in the single pass
o Multi group edit mode is automatically selected now for group name edit field when you enable "Override group name" option while holding <Ctrl> key. You may still manually toggle this mode with <Ctrl>+<M> hotkey anytime when editing the group name
o On-Screen Display item type (i.e. text, graph or combination of both) is now displayed in "Properties" column of active hardware monitoring graphs list in "Monitoring" tab in the application properties
o Added programmable hotkey for clearing monitoring history
o Added "Apply" button to application properties window. Now you may iteratively customize monitoring module without closing the properties to see the result on each step. Please take a note that some properties (e.g. application language) cannot be applied until you completely close properties window by design of application
o Application properties dialog window is now displayed with topmost style when the properties are activated from detached monitoring window and "Always on top" mode is enabled for it
o Now "Mark minimum" and "Mark maximum" commands are available in the context menu of monitoring window even when a fragment of history is not selected. In this case the commands result in setting tracking marker in a global extremum position. You may still use <Shift> key and mouse cursor to select a fragment of history then use the context menu to set tracker marker in local extremum position
o Now you may press <F11> key in monitoring window to capture print friendly screenshot of hardware monitoring history graphs. The screenshot includes MSI Afterburner watermark by default, you may customize it by replacing overlay.png file located in .\Graphics folder. This feature can be useful for hardware reviewers
o Now you may hold <Del> key then click unwanted graphs in hardware monitoring history viewer mode to hide them. This feature can be useful before capturing print friendly screenshot, if you want to exclude unnecessary graphs from it
o Improved On-Screen Display layout editor:
- System reserved variable slots 250-255 are now displayed as system variables in the layout editor
- Added embedded graphs support. Embedded graphs can be displayed directly in the text in a separate column, it can be convenient for displaying per-core CPU usages
- Added embedded graph width adjustment variable to the "Graph" property node
- Added new "Graph placement" property node. You can use it to place each graph on top of text, on bottom or make it embedded in in text column
- Added new variables to "Separators" property node. Now you may define independent separators for the graphs located on top of text part, for the text part and for the graphs located on bottom of text part.
- Slightly altered interpretation of prolog and epilog separators. Please take a note that prolog separator is no longer automatically appended with new line symbol, so you must specify it manually when necessary and epilog separator is now displayed below the bottom group of graphs
- The list of hardware monitoring items in "Add item(s)" dialog window is alphabetically sorted now
- Added macroses for embedding any data from monitoring module into OSD text (e.g. prolog). You may use macroses to display anything available in the monitoring module, e.g. %CPU temperature%
- Improved On-Screen Display hypertext formatting performance due to more optimal macro replace strategy
- Revamped "modern web" layout. New layout is demonstrating new text formatting features including big custom framerate counter, custom embedded background and On-Screed Display header, custom benchmark and system time indicators and embedded CPU and GPU usage graphs
- On-Screen Display layouts are saved in monitoring profiles now
o Improved HwInfo plugin:
- Added UPS load, power, input voltage and charge level data sources to default plugin configuration
- Improved voltage/frequency editor:
o Voltage/frequency editor window is now available on AMD GPUs. On AMD platform it allows you to edit core frequencies and voltages independently per each P-State:
- Similar to NVIDIA GPUs, you may either adjust each point frequency or voltage independently with both mouse and keyboard (<Up> / <Down> or <Ctrl>+<Up> / <Ctrl>+<Down> keys), hold <Shift> key and drag single point to apply similar frequency or voltage offset to all P-states or hold <Alt> key and drag single point to add the same offset to each P-State frequency or voltage offset
- You may press <PageUp> / <PageDown> keys to switch between frequency or voltage keyboard input focus for selected P-State
- Read only P-States are currently not tracked, which means that you can try to adjust the frequency and voltage for locked states but changes will be ignored when applying the curve
- P-States locking functionality is not implemented yet
o Now you may press <Tab> / <Shift>+<Tab> keys when a point is selected to switch to the next / previous point. This feature can be useful if you're fine-tuning the offsets from keyboard
o Now you may press <Enter> key when a point is selected to type in desired frequency or voltage offset for it
o Now you may press <Shift>+<Enter> keys when a point is selected to type in absolute desired frequency or voltage explicitly and let the editor to calculate the offset automatically
o Added undo/redo support:
- Now voltage/frequency curve editor is saving up to 1024 last states of the curve during editing and allows you to undo/redo changes with <Ctrl>+<Z> or <Ctrl>+<Y> / <Ctrl>+<Shift>+<Z> keys
- Undo history is discarded when you apply the curve
- Number of recorded undo/redo steps is displayed in square brackets in the editor window caption
o Slightly increased default voltage range for voltage/frequency curve. Now you may lock voltage to lower values if you're using voltage/frequency editor to downvolt and reduce power consumption on your NVIDIA GPU. Power users may customize the range further, the voltage and frequency limits are fully adjustable via the configuration file
o Now you may press <F5> key in the editor window to reread the curve from hardware. This feature can be useful when adjusting the curve in changing thermal environment
o Voltage and frequency axes are dynamically scaled now, so the captions do not overlap when window is too small
- Improved hardware control shared memory interface. During the past years, external applications like MSI Remote Server were using this interface for tuning GPU hardware settings remotely from external applications. The improvements are intended to allow connecting external stress testing and automatic overclocking related applications to MSI Afterburner via this interface:
o Now voltage/frequency curve on NVIDIA Pascal and newer NVIDIA GPU architectures is accessible via hardware control shared memory interface
o New hardware control shared memory interface command allows MSI Afterburner to load hardware settings from external application without immediately applying new settings to GPU
o Added notification message, allowing external applications to notify MSI Afterburner about new command written to hardware control shared memory. Without the notification, MSI Afterburner is executing external commands on each hardware polling iteration like before. Please refer to SDK and MACMSharedMemorySample source code to see notification message usage example
o Added hardware identification info to GPU entries in hardware control shared memory. Hardware identification info allows external applications to reconcile own enumerated devices with logical GPUs enumerated by MSI Afterburner
o Now hardware control shared memory is refreshed on delayed fan speed readback events
- New bundled MSI Overclocking Scanner application in now included in MSI Afterburner distributive:
o MSI Overclocking Scanner is currently supported on NVIDIA GTX 10x0 and NVIDIA RTX 20x0 series graphics cards under 64-bit operating systems only. On such systems you may activate the scanner with dedicated button from the main application window or directly from voltage/frequency curve editor window
o MSI Overclocking Scanner is powered by NVIDIA Scanner technology, which is using proprietary algorithms to quickly and reliably test manually overclocked GPU stability or find the maximum stable GPU overclocking in automatic mode with a single click. The scanner is using embedded NVIDIA test load to stress GPU. The scanner provides you two functional modes:
- In test mode MSI Overclocking Scanner is stress-testing your manual GPU overclocking settings during approximately 5 minutes. The result is returned as GPU stability confidence level (0% - unstable, 100% - stable)
- In scan mode MSI Overclocking Scanner is stress-testing and slowly increasing clocks on voltage/frequency curve points and this way automatically detecting the maximum stable GPU overclocking. The result is returned as modified voltage/frequency curve and average GPU overclocking in MHz
- Added framerate limiter compatibility settings group to "On-Screen Display" tab to the application properties. The settings include programmable hotkeys for globally disabling, enabling or toggling framerate limiting techniques of RivaTuner Statistics Server. The settings are intended to provide a way to dynamically enable or disable scanline sync technology based framarate limiting without altering application profiles, however you may use it to toggle traditional framerate limter as well
- Now CPU topology info (i.e. each logical CPU mapping to physical CPU package and core) is displayed in system info window
- Fixed kernel mode hardware access interface fix for AMD Vega GPUs. HBM temperature, GPU power and GPU voltage are no longer returning bogus values when kernel mode hardware access interface is enabled on AMD Vega series graphics cards
- Fixed low-level GPU usage monitoring for AMD Polaris GPU family. Software SMC registers offset is no longer hardcoded, offset detection algorithm is more future proof now. Please take a note that it will not fix zero GPU load issue when "Enable unified GPU
usage monitoring" option is enabled. This option implementation is based on low-level DirectX performance counters, which require OS and display driver WDDM versions to match. Current AMD drivers are WDDM 2.5 so this performance counter is only working when you're under WDDM 2.5 OS (Windows October Update). If you're under older OS version, this performance counter won't work unless you downgrade to WDDM 2.4 driver (18.9.3 or older)
- Hardcoded voltage/frequency curve clock multiplier implementation has been replaced with heuristic multiplier detection in order to provide unified voltage/frequency curve control implementation for NVIDIA Pascal and newer NVIDIA GPU architectures
- Improved realtime voltage/frequency curve editor GUI scaling. Now GUI is scaled property when adjusting skin scaling with open voltage/frequency curve editor window
- Improved report window, fan curve editor window, monitoring window and voltage/frequency curve editor scaling for scaling ratios greater than 100%
- Now mandatory MSI Afterburner installation option is greyed out and cannot be unchecked during installation
- Now 64-bit Visual C++ 2008 runtimes are also installed by MSI Afterburner installer. 64-bit runtimes are required for proper functionality of bundled MSI Overclocking Scanner application
- Multilanguage user interface library is DPI aware now. Main window skinned interface is no longer being scaled by OS and no longer looks blurred by default when greater than 100% DPI is selected. Now main skinned window interface can be manually zoomed with
skin scaling slider in "User interface" tab, and the properties are automatically scaled by OS according to selected DPI
- Added new skin scaling mode for power users. New mode provides better scaling performance at the expense of some scaling image quality loss
- Skin scaling implementation is now asynchronous, so increasing skin scaling ratio doesn't increase GUI update time and doesn't decrease GUI response time
- Skin scaling slider range has been extended from 75%-150% to 75%-200%
- RivaTuner Statistics Server has been upgraded to v7.2.1

RivaTuner Statistics Server v7.2.1

- Fixed issue with the latest NVIDIA Adaptive Shading update of Woflenstein II: The New Colossus locking on startup. Please take a note that now Woflenstein II: The New Colossus is presenting frames from compute queue in NVIDIA codepath similar to AMD codepath. Due to that reason, On-Screen Display rendering is performance expensive and disabled by default in such environment.Experienced users, understanding and accepting On-Screen Display related performance penalty, may reenable it with PresentFromCompute profile switch
- Fixed black screen issue in Vulkan applications on NVIDIA Kepler GPU family under 4xx.xx series drivers family
- Fixed multhithreaded active busy-wait loop based frame capture implementation, which could prevent desktop videocapture from working in the previous version
- Improved compatibility with multithreaded Direct3D1x applications, using multiple DXGI swapchains and concurrently accessing them from different threads (e.g. Microsoft Photos UWP application)
- Improved On-Screen Display hypertext formatting implementation:
o Variable slot 250 is no longer used to define own On-Screen Display statistics format, now it is allowing the client applications to redefine default text format. Such implementation allows the client applications like MSI Afterburner to edit default text color and size directly inside the On-Screen Display layout editor
o Improved subpixel precision for raster fonts provides better font scaling quality and improves rendering quality for small superscript/subscript-styled text
o Improved font baseline positioning. Now subscript-styled text is aligned on the baseline of maximum sized font symbol in the line instead of the baseline for 100% font size
o Improved font scaling implementation for large fonts. Now requested font size is scaled from the closest reference prerendered font size instead of 100% font size
o Changed set of prerendered font sizes from 40%, 50%, 80% and 100% to 50%, 100% and 200%. Prerendered font sizes can be used as is without scaling and with the best possible rendering quality, any different font sizes are interpolated
o Added background fill flag for embedded objects. Background fill is intended to simplify maximum value visualization with barchart-styled embedded graphs
o Now it is allowed to use zero width or height in bar embedding tags to specify whole text extent
o Embedded objects are now affected by text size and alignment tags
o Added backspace symbols support. Backspaces are intended to be used in conjunction with bar embedding tags. Inserting backspace symbol immediately after the bar embedding tag results in returning the cursor position back to embedded bar origin. Such implementation provides simplified way of embedding custom background in the hypertext. Please take a note that backspace sequences are currently not supported, so the cursor cannot be moved beyond the previous position
o Added new tag for displaying benchmark time
- Added suspending support to VTable hook handlers. Suspending is used to improve reference counter tracking implementation and make it more future proof
- Graphs are no longer displayed in On-Screen Display when Vector2D On-Screen Display rendering mode is selected
- Slightly refactored Direct3D and Vulkan On-Screen Display rendering codepaths due to implementation of optional offscreen rendering mode. This mode is currently disabled by default, it is reserved for future versions as a codebase for asynchronous On-Screen Display rendering implementation
- Multilanguage user interface library is DPI aware now. Main window skinned interface is no longer being scaled by OS and no longer looks blurred by default when greater than 100% DPI is selected. Now main skinned window interface can be manually zoomed with skin scaling slider in "User interface" tab, and the properties are automatically scaled by OS according to selected DPI
- Added new skin scaling mode for power users. New mode provides better scaling performance at the expense of some scaling image quality loss
- Skin scaling implementation is now asynchronous, so increasing skin scaling ratio doesn't increase GUI update time and doesn' t decrease GUI response time
- Skin scaling slider range has been extended from 75%-150% to 75%-200%
- Some profile settings are treated as power user oriented and they are locked by default at global profile level now. Such settings include "Enable Custom Direct3D support" compatibility option and Vector2D On-Screen Display rendering mode selection. Context help was not recommending enabling those compatibility related options globally, however many users tended to enable them blindly then blamed the product for inappropriate performance or reduced 3D applications compatibility. Such settings are now ignored and locked for enabling in global profile unless you manually unlock them
- Added "Enable framerate limiter" option to general application properties. This option allow controlling RivaTuner Statistics Server's framerate limiting support globally, so you may temporarily disable it if necessary without modifying generic framerate limiter or
scanline sync related settings in the profiles. The client applications like MSI Afterburner can also distantly control this option via hotkeys
- Now RivaTuner Statistics Server validates DirectX runtimes installation at startup and displays warning message if required DirectX runtime components are missing. Power users may disable this warning message as well as any previously existing diagnostic warning messages displayed at RivaTuner Statistics Server startup and enable silent startup mode via the configuration file if necessary
- Added user extendable exclusions list for desktop windows notification performed during installation and uninstallation of system CBT hooks. Currently the only exclusion in the list is Microsoft Outlook process, which previously tended to display help popup window on closing RivaTuner Statistics Server
- Now RivaTuner Statistics Server hides own frametime history overlay when framerate or frametime is displayed by the client On-Screen Display application
- Now RivaTuner Statistics Server hides own benchmark statistics when benchmark time, minimum, average, maximum, 1% low, 0.1% low framerate is displayed by the client On-Screen Display application
- Added On-Screen Display compatibility profile for Splinter Cell Chaos Theory
- Updated profiles list

Changelog Version 4.5.0
· Minimum, average, maximum, 1% low and 0.1% low framerates are now displayed in On-Screen Display with special text formatting tags introduced by new RivaTuner Statistics Server. The tags are allowing On-Screen Display clients to display independent benchmark statistics simultaneously for multiple running 3D applications instead of displaying foreground 3D application statistics only
· Improved default MSI Cyborg White skin. Monochrome on / off states of fan speed auto button were hardly identifiable before, they are more contrast now
· Added power user oriented restore points system. Experienced users may use new /backup and /restore command line switches to create multiple named restore points containing full backups of MSI Afterburner's settings (including hardware profiles and custom hardware monitoring plugin configurations) and restore settings from any previously created restore point if necessary
· Improved hardware monitoring module:
o Improved built-in performance profiler. Now you may enable "Show profiler panel" option is the context menu of hardware monitoring window to see additional panel with detailed per-sensor polling statistics in hardware monitoring window status area. Polling statistics visualizes information about the slowest polled sensors with maximum polling time, so power users can easily identify problematic sensors eating most of CPU time on each polling period (e.g. abnormally slow GPU power sensor in some versions of NVIDIA drivers)
o Improved correction formulas support. Now in addition to "x" variable representing current data source the formulas may also use sibling data sources. For example, you may use "x - "RAM Usage"" correction formula for "Pagefile usage" (commit charge) data source to subtract RAM usage from displayed value
o Fixed incorrect tracking markers rendering on the graphs dynamically added to hardware monitoring module
o Fixed incorrect tracking markers rendering when monitoring ring data buffer is full
o Added experimental support for Intel i7 and i9 7XXXX LGA2066 CPUs
o Added CPU package power monitoring for Intel CPUs
o Minimum sampling interval for CPU usage calculation has been reduced from 1000ms to 100ms
o Original RivaTuner's monitoring history fragment selection and selected fragment processing functionality is back! Now you may hold <Shift> and press left mouse button on initial desired position in hardware monitoring window to begin fragment selection, then drag mouse cursor to desired final position and release left mouse button to select a fragment. The following functionality is available for selected fragments:
§ When the fragment is selected, minimum and maximum displayed values are estimated within selected fragment only. This feature can be used if you don't need the global minimum and maximum values, estimated during whole monitoring session, and wish to see local minimum and maximum values estimated within some shorter period of time (e.g. during benchmark application runtime only)
§ When the fragment is selected you may use the context menu of any graph to set tracking marker into the local minimum or maximum position within the selection. This feature can be used to automate the process of identifying and visualizing the moments of reaching peak values (e.g. peak GPU temperature) on desired fragments
o Improved monitoring plugins architecture:
§ Added plugin descriptions to plugins selection window
§ Added new SetupSource API function allowing you to configure the plugins. This function is allowing you to customize the plugins either globally from plugin selection window (e.g. configure whole list of data sources exported by each plugin) or customize desired data source only directly from corresponding graph properties window (e.g. change network download rate units from MB/s to KB/s). SetupSource function usage is demonstrated in SDK in updated AIDA64 and PerfCounter plugins
§ Added new GetHostAppProperty API function allowing the plugins to retrieve various properties from the host application (i.e. MSI Afterburner), e.g. retrieve GUI color scheme specific to currently selected skin. GetHostAppProperty function usage is demonstrated in SDK in updated AIDA64 and PerfCounter plugins
o Improved monitoring plugins:
§ Now the plugins store user customized and built-in default configurations in separate files, so your custom plugin settings won't be lost on new version install
§ Added configuration GUI for AIDA64, HwInfo and PerfCounter plugins. Each plugin's user interface is allowing you to edit the list of sensors exported by each plugin, export full list of available sensors to a text file, customize each sensor's properties or reset plugin settings to defaults
§ Improved PerfCounter plugin:
· Added support for performance counters with non-localized names (e.g. "GPU Engine" under Windows Fall Creators Update)
· Added support for dynamic data sources. Dynamic data sources are not validated during creation, such sources are allowed to export no data until some condition is met (e.g. "CPU usage" performance counters specific to some target process export data only when the process is running)
§ Improved SMART plugin:
· Added airflow temperature SMART attribute support for Intel/Samsung SSDs.
§ Added new CPU plugin:
· The plugin fully duplicates MSI Afterburner's built-in CPU temperature monitoring implementation (with the only exception of AMD Ryzen codepath, which cannot be open sourced due to NDA) and shows third party plugin developers how to implement low-level CPU specific sensors in plugins using CPU MSR registers and PCI configuration space access API
§ Added new GPU plugin:
· The plugin shows third party developers how to extend MSI Afterburner's GPU monitoring functionality and implement own GPU specific sensors in plugins using GPU enumeration and identification API. The plugin is demonstrating implementation of D3DKMT GPU performance counters providing unified vendor agnostic per-engine GPU usage, dedicated and shared memory usage monitoring
· Fixed issue in context help system, which could cause the tooltip to flicker when it was displayed below mouse cursor
· RivaTuner Statistics Server has been upgraded to v7.1.0

RTSS v7.1.0:

· Added On-Screen Display locking mechanism for third party On-Screen Display client applications. The mechanism is aimed to eliminate unwanted On-Screen Display flickering effect when some client application is performing risky two-stage On-Screen Display refresh while On-Screen Display is being actively refreshed by another client. Please take a note that third party On-Screen Display clients must be also updated in order to use this mechanism and get rid of flickering
· Added new text formatting tags support for displaying minimum, average, maximum, 1% low and 0.1% low framerates in benchmark mode. The tags are allowing On-Screen Display clients to display independent benchmark statistics simultaneously for multiple running 3D applications instead of displaying foreground 3D application statistics only
· Now it is possible to adjust frametime history graph size via RivaTuner Statistics Server properties. Please take a note that you may use positive values to specify the size in pixels or negative values to specify it in symbols
· Now it is possible to toggle benchmark mode state from RivaTuner Statistics Server properties. However, third party benchmark client applications like MSI Afterburner are still required to toggle benchmark mode state with hotkeys during 3D application runtime and to save benchmark results to a text file
· Now it is possible to toggle between averaged or instantaneous calculation modes for peak (i.e. minimum and maximum) framerates for benchmark mode via RivaTuner Statistics Server properties
· Fixed issue in context help system, which could cause the tooltip to flicker when it was displayed below mouse cursor
· Fixed screen capture feature in On-Screen Display preview window when RivaTuner Statistics Server is installed in UAC-protected folder
· Updated SDK:
o Now RTSSSharedMemorySample sample code is demonstrating the implementation of On-Screen Display locking and flickering filter
· Updated profiles list

• Improved voltage offset calculation accuracy for AMD Fiji, Ellesmere and Baffin GPU families
• Improved voltage offset programming reliability on AMD Ellesmere and Baffin GPU families
• Minimum voltage offset has been extended to -200mV for AMD Fiji and Ellesmere GPU families
• Fixed stuck GPU usage and memory controller usage monitoring on AMD Radeon RX 500 series under 17.6.1 and newer drivers
• Revamped voltage control layer gives additional freedom to extreme overclockers with new custom design MSI graphics cards with Quad Overvoltage™ technology support. Now MSI Afterburner is able to control up to 4 independent voltages on custom design MSI graphics cards
• Improved 5-channel thermal monitoring module architecture provides support for up to 20 independent thermal sensors per GPU (up to 5 independent GPU, up to 5 independent PCB, up to 5 independent memory and up to 5 independent VRM temperature sensors) on future custom design MSI graphics cards

• New cached I2C device detection algorithm improves application startup time on the systems with multichannel voltage controllers or multichannel thermal sensors
• Improved third-party voltage control mode functionality. Now third-party hardware database can also include extended thermal sensors calibration and mapping info for third-party custom design graphics cards
• Added AMD Overdrive Next X2 overclocking API support for AMD Crimson 17.7.2 display drivers
• The unofficial overclocking mode is currently broken in AMD Crimson 17.7.2 display drivers, so MSI Afterburner is forcibly disabling unofficial overclocking mode and always using official ADL overclocking codepath on 17.7.2 and newer drivers. However, unofficial overclocking mode can still be manually unlocked via configuration file on 17.7.2 and newer drivers if AMD decides to provide a fix for unofficial overclocking mode in the future
• Improved PCI bus scanner provides support for low-level GPU access for the secondary graphics cards in Crossfire configuration on some platforms
• Fixed system freeze issues when starting MSI Afterburner on AMD Hawaii GPU while playing hardware accelerated video
• Fixed issue with opening wrong graph properties under certain conditions when right clicking a graph in hardware monitoring window and selecting "Properties" command from the context menu
• Improved voltage/frequency curve editor for GPU Boost 3.0 capable NVIDIA graphics cards:
  o Toggling locked curve point state with <L> key is working properly now and no longer resulting in setting a lock to a minimum clock/frequency point
  o Now you may hold <Alt> key while adjusting the offset of any point with mouse to move the curve up/down. That's equal to adding fixed offset to each point's offset
• Various parts of the hardware monitoring module have been pumped up to improve hardware monitoring usability and flexibility. Some new portions of old hardcore functionality from original RivaTuner are now available in MSI Afterburner:
  o Added clock monitoring for Intel CPUs
  o CPU temperature graph is now displaying data from dedicated package sensor on modern Intel CPUs instead of maximum core temperature. On older Intel CPUs with no dedicated package sensor the graph is still displaying the maximum core temperature
  o Added temperature and clock monitoring for AMD Ryzen CPUs
  o Added new "benchmark" tab allowing you to use hidden RivaTuner Statistics Server's benchmarking engine, which was previously available to reviewers only. The engine is providing you the following features:
  • You may define a hotkey for beginning framerate statistics recording. Once the recording begun, it stays active for all subsequently started 3D applications, even after rebooting the system
  • While recording is active you may enable showing own statistics in RivaTuner Statistics Server to see minimum, average and maximum framerate in the On-Screen Display
  • While recording is active you may press "_egin recording" hotkey one more time to restart the recording and reset the statistics
  • While recording is active you may press "End recording" hotkey once to end recording and save benchmark results to a text file, but keep the results shown in On-Screen Display. You may press the hotkey one more time to hide the results from the On-Screen Display
  • Statistics saved to a benchmark results file includes per-application total benchmarking time, total rendered frames number, global average, instantaneous minimum and instantaneous maximum framerates. Benchmark statistics file can be optionally either overwritten or appended on each recording session
  • Per-frame frametime statistics is being pushed to a named pipe so reviewers can use their own client software to collect and display it in realtime while any benchmark is running without system slowdown, which is typical for traditional per-frame frametime logging approach o New flexible On-Screen Display customization features powered by RivaTuner Statistics Server's text formatting tags and embedded objects:

• Added On-Screen Display layouts support. Layouts allow you to change On-Screen Display formatting and appearance style. Now you may switch between traditional classic On-Screen Display layout or new modern column-oriented On-Screen Display layout. Built-in layout editor allows you to customize pre-defined layout parameters in details
• New On-Screen Display item type selection settings allow you to display each item in On-Screen Display as a text or graph. The graphs displayed in the On-Screen Display can be useful to visualize frametime history and GPU usage history, and so on
• The maximum text length for "Override group name" setting is no longer limited by 8 symbols. Now you may embed new RivaTuner Statistics Server's text formatting tags directly into your custom group name, e.g. "<C=FFFFFF>GTX 1080<S=-50=1<S=<C=" to display it in On-Screen Display in white color and with 50% size subscript index
• Now it is allowed to override group names for "Framerate" and "Frametime" graphs, so you may append default application 3D API <APP> tag with some custom text or replace it completely if necessary
• Exactly the same flexible level of On-Screen Display customization output is available to any other RivaTuner Statistics Server client applications like AIDA, HWiNFO and others and will be available shortly

• Original RivaTuner's task scheduler functionality is back! Now you may define optional minimum and (or) maximum thresholds for any graph in hardware monitor module to track the most critical hardware health parameters, to be notified on reaching a critical threshold and to program some emergency actions (e.g. system shutdown) to be performed in this case:
  • User-defined thresholds are displayed on each graph to allow you to control each parameter safety zone visually
  • When the threshold is reached blinking warning icon is displayed in top left corner of monitoring window and in Logitech keyboard LCD if graph LCD display mode is selected
  • When the threshold is reached you can see the name of graph triggering the alarm in hardware monitoring status line
  • When the threshold is reached background of the graph triggering the alarm is highlighted with color to allow you to identify it visually
  • When modern On-Screen Display layout is selected, parameters triggering the alarm are highlighted by color in On-Screen Display to allow you to identify it easily
  • You may enable option alarm sound notification to be played when the threshold is reached
  • You may configure MSI Afterburner to launch any external application when the threshold is reached. This feature allows you to implement many different scenarios, e.g. perform emergency system shutdown or apply safe profile with reduced overclocking, maximized fan speed etc. In addition to selecting any custom external applications, built-in predefined applications browser allows you to select some common typical usage scenarios, such as command line based MSI Afterburner profile activation or system shutdown
    o Original RivaTuner's user extendable hardware monitoring plugins architecture is back! Now you may extend the list of hardware monitoring data sources with built-in or third party plugin modules, develop your own plugins to provide support for custom hardware sensors and share your work with community, and many more:
• The plugins can use full set of MSI !fterburner's low-level hardware access functionality: enumerate GPUs, access GPU registers, enumerate GPU I2C buses and access I2C devices, access CPU MSR registers, access IO ports and PCI configuration space registers. This way you can easily create your own plugins providing hardware monitoring functionality for any custom hardware. You can also create the plugins for importing OS-specific or third-party software specific performance counters into MSI Afterburner
• Open source SDK, demonstrating hardware monitoring plugins development principles to third party programmers.
• The SDK includes the following open source plugins:
  • SMART.dll - demonstrates HDD SMART attributes readback and HDD temperature monitoring
  • PerfCounter.dll - demonstrates the principles of importing native OS performance counters into
    MSI Afterburner. The list of imported performance counters includes but not limited to hard disk usage, hard disk read and write rates, free disk space on system partition, network download and upload rates. You may also add any other performance counter visible to OS (e.g. disk queue size or some specific process CPU usage) via editing the plugin configuration file
  • AIDA64.dll - demonstrates the principles of importing sensors from AIDA64 application via shared memory interface. The list of imported performance counters includes but not limited to motherboard temperature, CPU socket temperature, CPU fan speed, CPU voltage, CPU package power, +3.3V, +5V and +12V voltages. You may also add any other sensors available in AIDA64 via editing the plugin configuration file
  • HWInfo.dll -imports sensors from HWiNFO32/64 application via shared memory interface. The list of imported performance counters includes but not limited to motherboard temperature, CPU socket temperature, CPU fan speed, CPU voltage, CPU package power, +3.3V, +5V and +12V voltages. You may also add any other sensors available in HWiNFO32/64 via editing the plugin configuration file. Please take a not that the plugin is not open source per HWiNFO developer request
• Improved profiles architecture. Now MSI Afterburner can store hardware monitoring module settings in the profile slots. This allows you to switch between different On-Screen Display configurations on the fly with hotkeys bound to profile slots. You may configure desired profile slot contents in new "Profile contents" settings group in "Profiles" tab
  o Added experimental interleaved hardware polling mode, aimed to reduce hardware polling time on the systems with multiple polled I2C devices. When interleaved polling is enabled, just a part of hardware monitoring data sources is being polled on each hardware polling period, so it takes multiple periods to refresh all monitoring data sources. Power users may enable interleaved hardware polling mode via the configuration file if necessary
  o Added ability to define a hotkey for hardware monitoring logging start and stop
  o Now the path to hardware monitoring logs supports macro names:
• You may use new %ABDir% macro in the path to specify relative path to current MSI Afterburner installation directory. This macro allows you to use logging if you are using portal installation and start MSI Afterburner from removable drive
• You may use new %Time% macro in the path to make hardware monitoring sessions to be stored in unique timestamp-named log files instead of single multi-session log file
• Changed hardware monitoring properties layout, the controls have been reordered a bit to give more compact and convenient look to the properties
• Changed default hardware monitoring graphs order. GPU related graphs have been reordered a bit in order to provide more convenient layout on multi-GPU systems. "Framerate" and "Frametime" graphs have been moved to the bottom of the list
• Now you may right-click the list of active hardware monitoring graphs and select "Reset order" command from the context menu to restore default active hardware monitoring graphs order
• The maximum limit for "Frametime" graph has been decreased to 50ms (20 FPS) by default
  Improved drag and drop implementation for the list of active hardware monitoring graphs. Now it is possible to drag and drop items below the bottom edge of the list to move the graphs to the end of the list
• Improved multiple selection functionality:
  • Now you may hold <Shift> key when clicking a checkmark next to a graph name in the list of active hardware monitoring graphs to enable or disable all graphs at once
  • Now you may hold <Shift> or <Ctrl> keys to select multiple items in the list of active hardware monitoring graphs. The following functionality is available for multiple selected hardware monitoring graphs: • Multiple selected graphs can be dragged and dropped when rearranging the graphs • When multiple hardware monitoring graphs are selected, you may hold <Ctrl> key when changing
    graph specific On-Screen Display, Logitech keyboard LCD and tray icon related properties (e.g. "Show in On-Screen Display" property) to change it synchronically for all selected graphs
  • When multiple hardware monitoring graphs are selected, you may hold <Ctrl> when clicking a checkmark next to a graph name in the list of active hardware monitoring graphs to enable or disable all selected graphs at once
  • When multiple graphs are selected you may press <Ctrl>+<M> inside group name edit field to apply group name changes synchronically to all selected graphs Now "Override graph name" and "Override group name" checkboxes are also affected by multiple selection functionality, so you may hold <Shift> when toggling those options to toggle it synchronically for all graphs or hold <Ctrl> when toggling those options to toggle it synchronically for all selected graphs.
• Improved system information window. Now 3D API usage info, x64 and UWP application architecture attributes are displayed for each currently running process in the list of active 3D applications
• Now the installer is preserving installation path
• RivaTuner Statistics Server has been upgraded to v7.0.0

Changelog Version 4.3.0 Final

• Added AMD Ellesmere and Baffin graphics processors families support
• Added Overdrive N (Overdrive 7) technology support for AMD Polaris architecture based graphics cards
• Added core voltage control for reference design AMD RADEON RX 460, AMD RADEON RX 470 and AMD RADEON RX 480 series cards with on-die SMC voltage controller
• Added memory controller usage graph to hardware monitoring module for AMD graphics cards. Currently memory controller usage monitoring is implemented for AMD Ellesmere and Baffin graphics processors families only
• Added GPU power draw graph to hardware monitoring module for AMD graphics cards. Currently GPU power draw monitoring is implemented for AMD Ellesmere and Baffin graphics processors families only
• Added "Erase autosaved startup settings" option to "AMD compatibility properties" section in "General" tab. Starting from AMD Crimson drivers family, the driver is automatically saving hardware settings (e.g. overclocking or fan control settings) in the registry and apply it at Windows startup. It makes settings of any third party hardware overclocking tool virtually permanent, meaning that applied settings stay in the system even after rebooting or powering down the system. However, such implementation is unsafe and even potentially dangerous, because you're no longer able to undo unsafe overclocking with system reboot or even driver reinstall. To prevent such situations, MSI Afterburner can now optionally erase AMD driver's autosaved startup settings after applying new settings to hardware
• Added GPU Boost 3.0 technology support for NVIDIA Pascal graphics cards:
  • Added percent based overvoltage support
  • Added voltage/frequency curve customization support. You may use traditional core clock slider on NVIDIA GeForce GTX 1070 and 1080 graphics cards to apply fixed offset to all voltage/frequency curve points as well as use brand new flexible voltage/frequency curve editor window for more precise per-point curve adjustment. The editor window can be activated either with "Voltage/frequency curve editor" button in the main application window or with <Ctrl> + <F> keyboard shortcut and it provides you the following features:
  • You may independently adjust clock frequency offset for each point with mouse cursor or <Up> / <Down> keys
  • You may hold <Ctrl> key to set anchor and fix clock frequency offset in minimum/maximum voltage point and adjust the offset of any other point with mouse to linearly interpolate the offsets between the anchor and adjustment points
  • You may hold <Shift> key while adjusting the offset of any point with mouse to apply the same fixed offset to all points. That's equal to adjusting the offset with the slider in main application window
  • You may press <Ctrl> + <D> to reset offsets for all points
  • You may switch between traditional core clock control slider in the main window and voltage/frequency curve editor window to see how they affect each other in realtime
  • You may press <L> after selecting any point on the curve with mouse cursor to disable GPU dynamic voltage/frequency adjustment and lock the voltage and core clock frequency to a state defined by the target point. This feature allows you to test graphics card stability independently for each voltage/frequency point of the curve using real 3D applications or any stress test of your choice. In addition to stability testing usage scenario, MSI Afterburner allows you to save a curve with locked point setting to a profile, so you may easily switch between dynamic voltage/frequency management and fixed voltage/frequency settings in realtime (e.g. to achieve the maximum performance during benchmarking). Please take a note that fixed voltage and frequency settings do not allow you to disable power and thermal throttling
• Increased default maximum limits for "Core clock", "Memory clock" and "Memory usage" graphs to improve graphs readability on NVIDIA Pascal series graphics cards
• Added configuration file switch, allowing you to toggle the source for "Power" graph on NVIDIA graphics cards. Normalized total power draw (i.e. normalized value from multiple power sensors installed on the graphics card) is selected by default per NVIDIA recommendation, however you can configure MSI Afterburner to display power draw from GPU sensor only
  • Improved representation of performance limits graphs for NVIDIA graphics cards per NVIDIA recommendations:
    "Voltage limit" and "OV max limit" graphs have been merged into single "Voltage limit" graph
  • "Utilization limit" graph has been renamed to "No load limit" graph
  • "SLI sync" graph is now hidden on the systems with single NVIDIA GPU
  • Improved representation of performance limits graphs in On-Screen Display or in Logitech keyboard LCD. Now the names or currently triggered performance limits are being displayed in On-Screen Display or in Logitech keyboard LCD instead of previously used binary limits representation form

- RivaTuner Statistics Server has been upgraded to version 6.1.0First, ensure that your hardware supports QuickSync Video technology. The following hardware is required:

• Intel CPU with QuickSync Video technology support (SandyBridge, Ivy Bridge or Hawell core). You may use this link into to see if your Intel CPU supports this technology.
• Mainboard with integrated Intel HD graphics support (refer to your mainboard specs to see it)
• To use QuickSync on such platform you must:
• Enable Intel HD graphics in your mainboard BIOS. If it is enabled correctly, you must see Intel HD graphics active in your device manager next you your discrete AMD/NVIDIA graphics card
• Install the latest Intel HD graphics driver. QuickSync works via Intel HD driver so using outdated driver may degrade encoding performance drastically
• There are 3 QuickSync acceleration modes available in MSI Afterburner:
• Disabled acceleration - uses CPU software emulation. It is left for performance testing/debugging only and it REQUIRES additional Intel Media SDK installation. It is not recommended to use this mode.
• Direct3D9 acceleration - uses Direct3D9Ex accelerated encoding. This mode is only available under Windows Vista and newer OS. This mode REQUIRES connecting monitor to Intel HD graphics output or forcing monitor detection for Intel HD graphics. Detailed instructions on forcing monitor detection for enabling QuickSync can be found here.
• Direct3D11 acceleration - uses Direct3D11.1 accelerated encoding. This mode is only available under Windows 8 and newer OS. This mode doesn't require any monitor detection tricks so it is strongly recommended to use it if it is available (i.e. if you're under Windows 8).

To verify that everything is set up properly just hit the button. It will try to encode some short video in your current desktop resolution and show you the results. If you system is not configured properly, benchmark won't start.

Note: some of you have been wondering about the new skin in the screenshot. You can download these below, located at Dragon Army Skins. Enjoy.

Changelog Version 3.0.0 Beta 18
• Added low-level I2C access driver for AMD Bonaire, Curacao and Hawaii graphics processors. Low-level I2C access driver provides much faster access to I2C bus than ineffective native AMD ADL I2C access interface and addresses issues with GPU clock throttling when enabling voltage monitoring on AMD RADEON R9 290 series graphics cards
• Improved AMD ADL access layer with Overdrive 6 support to provide compatibility with future AMD GPUs
• Regular and SE versions of MSI Afterburner are now merged into single installer. Added voltage control mode selection option to the "Compatibility properties" section in "General" tab. Now you can toggle between reference design, standard MSI and extended MSI voltage control modes

or for prerecording videos with low compression ratio (e.g. lossless Lagarith video)
> Prerecord to RAM. This mode suits best for prerecording short videos (e.g. a couple minutes of H.264 video) and it
provides a bit better performance than prerecord to file. Also, unlike prerecord to file, prerecord to RAM minimizes
writes so it can increase the lifetime of SSD if you plan to use the prerecording frequently
• Improved muxer architecture with better extendibility makes it much easier to add new video containers support in future versions
• Fixed incorrect minutes being shown in video capture timer in On-Screen Display for videos longer than 1 hour

• Added Turkish localization

RivaTuner Statistics Server 5.3.2:
• Improved encoding plugins architecture:
> Now the plugins can be optionally loaded either in host 3D application address space or in dedicated encoder server application address space. Dedicated encoder server usage reduces the peak encoding performance a bit, however it may give you the following advantages in conjunction with Intel QuickSync H.264 encoder plugin:
- Minimization of different Direct3D synchronization/multithreading related issues. Host application 3D engine NVIDIA/AMD Direct3D device and encoder Intel Direct3D device are now isolated from each other and run in different address spaces and have much less chances to affect each other. Multithreaded optimizations no longer being forcibly disabled when capturing videos in Direct3D9 applications via Intel QuickSync H.264 plugin working in Direct3D9 mode with dedicated encoder server
- Now it is possible to use hardware accelerated Intel QuickSync H.264 encoder plugin to capture video from the games using modified Direct3D runtime libraries
- Now it is possible to use software emulation mode for Intel QuickSync H.264 encoder without installing Intel Media SDK. Intel software emulation libraries are distributed with encoder server
> Now the plugins can optionally provide extended error reporting info
• Improved Intel QuickSync H.264 encoder plugin:
> Added dedicated encoder server support
> Added extended error reporting support
> Recompiled under Intel Media SDK 2013 R2

Changelog Version 3.0.0 Beta 14:
• Add MSI new card supported
• Added NCP4206 voltage regulators support to provide compatibility with future custom design MSI graphics cards
• Improved voltage control layer architecture provides better compatibility with automatic voltage control on NCP4206 voltage
regulators
• RivaTuner Statistics Server updated to version 5.3.0 with the following improvements:
• Added external encoding plugin modules support. Plugin modules architecture provides an easy way to implement different hardware accelerated video encoders in RivaTuner Statistics Server.
• Added benchmark mode for external encoding plugin modules. Benchmark mode allows you to verify if hardware encoder is configured and working properly as well as estimate expected hardware encoding performance.
• Added external QSV.DLL encoding plugin. The plugin provides you high-performance hardware accelerated H.264 encoding on Intel QuickSync Video capable platforms. Intel QuickSync H.264 encoder is able to compress 1080p video at 60 FPS with no major CPU performance hit. Hardware accelerated Intel QuickSync H.264 encoder was introduced special to compete with NVIDIA's ShadowPlay hardware accelerated H.264 encoder. Free hardware accelerated H.264 video capture and encoding is no longer an exclusive selling point of NVIDIA Kepler GPU family, now the same functionality is available on much wider range of hardware platforms on both AMD and NVIDIA GPU based graphics cards absolutely for free!
• Tweaked encoder queue depth. The queue depth is no longer hardcoded to 32 frames, now it is equal to recording framerate
• Decreased server startup time on OS versions with no any service pack version installed
• Improved function offsets cache validation algorithm in hooking system
• Added proxy Direct3D library protection system. Now RivaTuner Statistics Server forcibly disables application hooking and blocks OSD, screen capture and video recording functionality if application is running via the proxy Direct3D runtime library (various game mods based on hacked D3D DLLs). Compatibility with most of such applications can still be improved by enabling custom Direct3D runtime libraries support in the application profile

changelog version 2.2.0 beta 11:

• added memory voltage control for reference design amd radeon 7970 graphics cards with chl8228 voltage regulators
• now msi afterburner displays target vid instead of real voltage sensor reading on "gpu voltage" graph on graphics cards equipped with chl8228 voltage regulators. these changes are implemented to avoid confusing the beginners and prevent the hysteria about voltage drop on amd radeon 7970 series graphic cards spreading across different discussion forums. experienced users, understanding the difference between target and real voltages, may still unlock the previous real voltage monitoring mode via editing the hardware profiles
• core and memory clock limits have been extended to 180% on amd radeon 7970 graphics cards in unofficial overclocking mode
• now msi afterburner's startup daemon routine precaches vrm i2c registers state at the first windows startup. precached vrm state is being used to detect default voltage instead of hardcoding default voltages into the database. please take a note that you may forcibly perform precaching later with command line switch or disable the precaching at all via configuration file if necessary and force msi afterburner to use the previous hardcoded database based default voltage detection
• msi on-screen display server has been upgraded to version 4.3.1. new version gives you the following improvements:
- added workaround for amd opengl driver context switching issues causing abnormally low framerate in id software rage when osd is enabled

changelog version 2.0.0 final:

# voltage control layer has been seriously revamped to give additional freedom to extreme overclockers with new custom design msi graphics cards. now msi afterburner is able to control up to 3 voltages on custom design msi fermi and other future custom design msi graphics cards. new adjustable voltages include memory voltage and special multi-purpose auxiliary voltage feeding either memory bus (also known as vddci on amd graphics cards) or pcie bus and crystal (pexvdd on nvidia graphics cards)
# added core, memory and auxiliary pexvdd voltage control for custom design msi n480gtx lighning series graphics cards with up6225+up6262 voltage regulators
# added core, memory and auxiliary pexvdd voltage control for custom design msi n470gtx twin frozr ii ov3 series graphics cards with up6218+up6262 voltage regulators
# added core, memory and auxiliary pexvdd voltage control for custom design msi n460gtx hawk series graphics cards with up6262 voltage regulators
# added core voltage control for custom design msi n460gtx cyclone series graphics cards
# added auxiliary vddci voltage control for reference design amd radeon hd 5870 series graphics cards
# added fan tachometer monitoring for nvidia graphics cards. please take a note that not all graphics cards are tachometer reading capable. so depending on graphics card and cooling system fan tachometer monitoring can be unavailable
# optimized nvidia driver-level clock frequency monitoring codepath
# minimum clock limits for all graphics cards have been reduced from 75% to 50%
# dynamic overclocking, voltage and fan speed limits. msi afterburner no longer uses static slider limits calibration and adjusts the limits dynamically when some external factors affect it (e.g. overdrive clock limits on amd cards or vga bios fan speed and voltage limits on nvidia geforce gtx 400 cards)
# new temperature hysteresis settings for software automatic fan control mode gives you additional way to improve cooling system thermal and acoustic parameters
# now fan speed limits (i.e. minimum and maximum fan speeds accepted by vga bios and display driver) are displayed in custom fan speed curve editor window
# built-in skin sizes have been reduced due to optimized internal skin panels representation and optimized compiled bitmap cache
# optional skin compression ability in the built-in skin compiler. skin format reference documentation has been updated to document new compression options
# minor built-in skins appearance tweaks
# now msi afterburner uses previously undocumented power user oriented startup mode via the task scheduler under windows vista / windows 7. msi afterburner launch no longer requires uac confirmation at windows startup. please take a note that microsoft visual c++ 2008 runtime libraries must be installed to get new startup mode working
# now msi afterburner automatically fixes startup link if [start with windows] or [apply overclocking at system startup] is enabled but the registry or task scheduler startup entry is missing
# startup profile is now displayed in [apply at windows startup] option floating tooltip instead of the main window
# now power users can enable optional directinput based hotkeys handler via the configuration file. directinput based hotkeys processing can seriously reduces hotkey response time in the applications heavily loading cpu (mostly 3d games) and leaving not enough time for processing standard keyboard input message queues. please take a note that enabling such sophisticated hotkeys handling mode can cause some system security applications (e.g. pro-active application behavior analysis module of kis) to warn you about possible keylogging threat
# improved skin engine, now skinned controls support horizontal and/or vertical centering. skin format reference guide has been updated to document these new alignment modes
# msi on-screen display server has been upgraded to version 3.7.2. new version gives you the following improvements:
# now screen capture events are identified visually by text message flashing in on-screen display during 0.25s
# built-in skin sizes have been reduced due to optimized compiled bitmap cache
# added on-screen display profile for startcraft ii : wings of liberty
# added configuration file switch allowing sending msi afterburner to system tray instead of closing on button click
# [start the task only when computer is running on ac power] option is no longer set in the startup task settings to allow automatically starting application via the task scheduler on laptops or on some ups models
# added optional data filtering mode for all hardware monitoring graphs. now it is possible to enable special math data filtering algorithm independently for each hardware monitoring graph to reject misreading spikes caused by sensor access conflicts when running multiple hardware monitoring tools at the same time
# now it is posssible to use both core and shader clock as the primary clock when adjust the clocks in linked mode
# fixed videomemory usage monitoring for non-primary nvidia graphics cards
# application restart is no longer required to apply new user interface language
# updated localization engine. now floating tooltips based context help system supports macro definitions
# localization reference guide documentation has been updated to v1.1
# various typo fixes in different language packs

changelog version 1.6.1 final:

bisher noch nicht veröffentlicht. support für die geforce gtx 460 liegt nahe.

changelog version 1.6.0 final:

• added nvidia geforce gtx 400 series graphics cards support (including voltage control!)
• added voltage control for msi n240gt low profile series graphics cards
• changed marketing name for msi r5670-pd512 in hardware database
• added basic screen capture support by means of built-in screen capture engine of msi on-screen display server. now it is possible to assign the hotkey for capturing screenshots in bmp,png or jpg formats on desktop, in directx or in opengl applications
• added hardware monitoring history logging support. now msi afterburner is able to save history in native rivatuner hardware monitoring log file format. the log files captured with msi afterburner can be viewed in any text editor like notepad or in graphics form in rivatuner's hml file viewer (rivatuner must be installed for viewing log files in graphics form)
• added new safety option allowing forcring constant voltage on some cards with voltage regulators supporting programmable dynamic voltage management (e.g. vt1165 or up6266). new safety option may improve stability on some systems a well as provide power state independent voltage control on the systems with non-standard voltage control implementation
• screen capture and on-screen display hotkey events are now being processed via direct connection to the on-screen display server instead of command line. due to this change screen capture and on-screen display visibility control hotkeys are being processed faster now
• msi on-screen display server has been upgraded to version 3.7.1. new server gives you a lot of improvements including:
• directx11 on-screen display and screen capture support
• directx screen capture engine is no longer using directx runtimes to capture and compress screenshots. screen capture and compression to png/jpg formats in directx applications is now handled by own more effective libpng/jpeglib based library
• png and jpg screen capture support for desktop and opengl applications
• adjustable jpg screen capture quality for experienced users
• screen capture support for directx10 and directx11 applications using multisampled antialiasing or non-standard frame buffer formats (e.g. srgb)
• optional on-screen display 3d rendering mode. new mode uses 3d accelerated directx functions to emulate previously used 2d framebuffer access functions and render 2d text. new rendering mode provides on-screen display support in directx10 and directx11 applications using multisampled antialiasing and can also drastically reduce osd related performance hit on the systems with badly optimized 2d acceleration in display drivers
• simplified on-screen display coordinate space settings. rarely used desktop and window coordinate space modes have been merged into single framebuffer coordinate space mode
• now the server automatically selects framebuffer coordinate space instead of viewport coordinate space when viewport is not accessible (e.g. if pure direct3d8 device is in use)
• improved application notification scheme during runtime profiles adjustment. now runtime changes in osd application profiles (e.g. osd zoom ratio change on the fly) are reflected in affected application almost immedaitely instead of approximately 1 second delay in the previos versions
• reduced runtime skin engine memory footprint due to dynamic skin storage unloading
• improved race condition protection system for multithreaded 3d engines (e.g. age of dragons : origins and arma ii)
• improved race condition protection system for the systems running multiple osd applications simultaneously (e.g. osd server, fraps and steam in-game chat)
• improved floating injection address hooking technology. due to more advanced built-in code analyzer hooks can be injected deeper into 3d application code if stealth mode is enabled. these changes improve stealth mode compatibility with third party tools using similar stealth injection technologies (e.g. fraps v2.9.8 and newer)
• now stealth mode cannot be toggled during 3d application runtime to reduce the risk of crashing 3d application
• removed single screen capture per second limitation
• updated profiles list

• added button for locking profiles modification
• now voltage control is also locked by default in safety options in advanced msi afterburner properties
• added accessibilitycheckingperiod configuration file switch for improving the compatibility with amd ulps power saving technology on crossfire systems. the switch allows low-level monitoring module to use amd driver api to check gpu accessibility and detect and display gpu sleep state properly. please take a note that amd api implementation is ineffective and hardly suits to realtime monitoring due to high cpu stress resulting in periodic stuttering in games.
that is why the compatibility switch is disabled by default, enable it only if you absolutely need to see slave gpu sleep state on the graphs and accept side effects like performance drop and stuttering resulting from ineffective amd api implementation
• added nvidia gt240m pci deviceid range to the core to provide more efficient hardware monitoring via low-level core on mobile nvidia gt240 based systems (bonus feature, official mobile systems support is still not declared)

• added voltage control for custom design msi r4770 cyclone graphics cards series with up6204 voltage regulators
• ineffective and slow temperature, clock, gpu usage and fan speed monitoring implementation provided by native amd's adl sdk has been replaced with own more effective low-level codepath. due to new codepath hardware monitoring related cpu performance hit has been reduced drastically on the systems with amd graphics cards and drivers.
• on-screen display and logitech lcd monitoring modules no longer explicitly read displayed data from hardware and retrieve cached data from monitoring graphs instead. due to this change cpu performance hit is reduced when osd or lcd monitoring features are enabled.
• fan speed slider position and numeric fan speed input field are now being refreshed in automatic fan speed mode only when msi afterburner window is active.
• added configuration file switch allowing power users to unlock unofficial overclocking codepath in amd display drivers (similar to amdgpuclocktool, atitool and rivatuner overclocking implementation on amd graphics cards).
unlike amd's official adl sdk overclocking ways, unofficial ones are not limited with ccc clock limit but have some alternate disadvantages (e.g. powerplay support limitation).
please take a note that unofficial overclocking methods are not supported either by amd or by msi, so unlock and use it at your own risk.
• now it is possible to toggle performance profiler status info visibility in hardware monitor window via [show status] option in the context menu.
• fixed l6788a database entry for amd radeon hd 4770 series graphics cards
• gpu voltage monitoring feature is now locked and not available by default.
unfortunately some inexperienced users don't understand the risk of running multiple tools accessing voltage regulator at the same time and tend to use helper voltage monitoring features in everyday hardware monitoring sessions in conjunction with third party vrm monitoring tools, intensively writing data to vrm and periodically causing it to enter wrong state due to write collision. unfortunately such issues are wrongly treated by certain users as instability of our product. to prevent such rumors, since this version voltage monitoring feature is no longer available to beginners by default.
experienced users understanding these specifics and accepting these risks may unlock voltage monitoring features via new safety option in [general]tab
• amd rv8xx i2c microcontroller is now being forcibly reset prior to starting new i2c transaction to minimize the risk of i2c collisions with third party tool without i2c synchronization protocol support (e.g. amdgpuclocktool)
• added safety option allowing users to disable voltage control feature if it is not needed
• now afterburner forcibly changes memory clock for all performance levels at once on amd graphics cards with equal default memory clocks defined for all performance levels to bypass flickering issue caused by incorrect powerplay dynamic memory clock changing implementation on some cards
• added catalyst driver family version detection for amd graphics cards
• added option to display system time in the on-screen display
• added red and blue editions of default skin
• various minor user interface and skin tweaks
• added configuration file switches allowing power users to tweak afterburner startup process and define startup delay or force the startup to be handled by windows vista / windows 7 task scheduler to bypass uac evaluation window (additional microsoft visual c++ 2008 runtime libraries installation is required for task scheduler based startup way)
• msi on-screen display server has been upgraded to version 3.6.0. new server provides improved desktop windows notification mechanism and also features optional power user oriented task scheduler based startup way
• added skin format reference documentation. now third party skin designers may use this local offline documentation to create their own skins for msi afterburner. official msi afterburner skin creation contest is approaching!
do you feel that you can design nice skins for msi afterburner? stay tuned and don't miss your chance to win the prize!
