Alien Swarm low-end config

Alien Swarm logo Alien Swarm looks really pretty. It's also unplayable if you have an integrated graphics card. I'm tried to make a low-end configuration file akin to this [Half Life 2 netbook config](http://netbook-gaming.co.uk/hl2.php).

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
