Performance Tweaks
From The DarkMod Wiki
Valid for all Releases
- Run Doom3 in fullscreen
- Turn the video resolution down
- Turn down anisotropic filtering (in DoomConfig.cfg), because it defaults to 8
- Turn off "High SFX" in the graphic settings
Releases after Thief's Den
- set the "Ambient Rendering" to "Fast"
- rename /darkmod/glprogs/interaction.vfp (e.g., interaction.bak.vfp) so that it is not used; ambient lighting will not look as good, but you may gain a few frames per second
- enable image downsizing: at the console, set "image_downSize" to "1" and then set a limit with image_downSizeLimit, e.g., "image_downSizeLimit" "128". This reduces texture memory requirements and may completely alleviate hard drive thrashing. There are similar cvars for bump and specular maps as well.
