High FPS config for Left 4 Dead 2

left-4-dead-2

A friend of mine is having a little trouble running Left 4 Dead 2 because of a weak graphics card. He consistently gets around 10 FPS. I've been looking around for a high FPS config for this game, but I haven't found any. I had the same trouble running TF2 on my netbook once, and using one of these configs was amazingly effective.

Is there any config file (autoexe.cfg) out there to minimize all possible settings and maximize performance for L4D2?

Note: I did find 2 configs. But the first one doesn't really minimize settings (it only optimizes stuff), and the second is just a TF2 config copy-pasted.

Have you tried running in software mode? You have to edit the shortcut to L4D2 and add the option -soft as listed here. It's horrible to look at but if he has a faster CPU it may increase performance. We used to play Unreal and Half-Life this way at my workplace using our crappy onboard graphics cards.

Alternately, try OpenGL -gl or Direct3D -d3d modes to see which works the best.

-autoconfig option might also be worth checking out:

Restores video and performance settings to default for the current hardware detected. Ignores settings inside any .cfg files until this parameter is removed.
