Alien Swarm low-end config2010-07-25
On my Intel X3100 GMA, it’s still unplayable. I hit peaks of 20 FPS. The fog and particle systems really seem to bog things down, dropping the FPS to 3 areas like on the first level. Unfortunately, you can’t disable them; Valve has them marked as “cheats.” Never mind completely disabling the lighting system would be much more of a cheat in this game, and you can already do that.
Launch options: -dxlevel 90 -w 480 -h320
Paste these options into a file. Save it as autoexec.cfg in C:\Program Files\Steam\steamapps\common\alien swarm\swarm\cfg
