Mirror's Edge: Physx effects benchmark review
DICE's Mirror's Edge is the first big title that, due to Physx, displays additional effects exclusively on the PC. PC Games Hardware checked how visualization and gameplay are effected and also tested the required performance.
Mirror's Edge - Physx effects reviewed: Introduction
Mirror's Edge is a visually and technically unique title: Besides the Unreal Engine 3 and lighting renderer Beat from Illuminate Labs Developer DICE (Digital Illusions Creative Entertainment) also utilizes the Ageia's Novodex Physics Engine - better known as Nvidia Physx. The latter one is a middleware that is used in combination with the UE3.
Compared to the console version the PC counterpart shows off with additional physics effects, which can be switched on/off in the video options. If those are activated, bursting window panes, the interactive fragments of which can wound or even kill an opponent, create a more realistic atmosphere and a obviously better visualization. Furthermore there is dynamic, environmental reactive smoke and a Cloth Simulation that makes cloth interact with bullets or the wind.
Mirror's Edge - Physx effects reviewed: Processor or Geforce?
There are two possibilities to have the additional effects calculated: Either the processor does it (for Radeon graphics cards or Geforce 7 and older Nvidia cards) or a GPU Physx compatible Geforce graphics card (Geforce 8 or better). IF you choose the GPU accelerated Physx you also can use a second Geforce card and have it calculate nothing but the Physx workload. To do so you select the card intended for Physx in the driver panel. It doesn't matter if you are using Vista or XP since Physx work on both operating systems. And because Mirror's Edge is a D3D9 game the graphics look the same on XP and Vista, too.
