Left 4 Dead: Video options tuned plus benchmarks
Left 4 Dead offers some real cool zombie action. But if your PC is going down because of the stress, our tuning could solve the problem. We explain what visual difference is cause by the individual options in the video settings.
Left 4 Dead - Graphics tuning: Introduction
Like almost any game Left 4 Dead has a video menu. Due to the Source engine many options allow an individual graphics setup according to one's preferences. PCGH explains how the options affect the visual appearance and the performance.
Left 4 Dead - Graphics tuning: Effect of the individual options
For pictures of the different Left 4 Dead graphics settings see the article Left 4 Dead: Graphics settings compared.
Left 4 Dead supports the common 4:3 and 5:4 resolutions and also offers the two widescreen modes 16:10 and 16:9. Here the field of view is increased.
Depending of the graphics card in use resolutions between 640 x 480 to 2,560 x 1,600 pixels can be applied. The offered resolutions also depend on the selected aspect ratio.
• Film Grain Amount
As know from the movie industry, this option puts a graining filter over the whole picture. This option can, depending on one's own preferences, lower or increase the visual quality.
Besides 2x to 8x MSAA the CSAA modes are available on Geforce cards. Contrary to Half-Life 2 Episode 2 the vegetation is not smoothed via Alpha to Coverage.
• Filtering Mode
The anisotropic filtering, which sharpens textures, can be set up to 16:1. Additionally trilinear and bilinear (ugly) filtering is offered, too.
• Shader Detail
Very high Shader details show off with rain effects, water reflections and Specular Maps. On low level those effects are deactivated and Left 4 Dead looses a lot of visual attractiveness.
Under this rather unfortunate name the settings for shadows and parts of the level geometry are filed. On low setting the characters and zombies don't cast shadows and details like metal girders or parts of the vegetation vanish - the atmosphere suffers a lot.
• Model/Texture Detail
Decreased model details for example result in less round objects and furthermore all textures are washy. The graphics suffer vitally from this.
