•
Aspect RatioLeft 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.
•
ResolutionDepending 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 AmountAs 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.

Anti-Aliasing Mode 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 ModeThe anisotropic filtering, which sharpens textures, can be set up to 16:1. Additionally trilinear and bilinear (ugly) filtering is offered, too.
•
Shader DetailVery 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.

Effect DetailsUnder 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 DetailDecreased model details for example result in less round objects and furthermore all textures are washy. The graphics suffer vitally from this.
