kabuto202: I'm getting only about 20 fps on medium settings. (Ubersampling is turned off, latest drivers, and no 3D drivers).
3.2 Ghz Quadcore Amd
8 gigs of RAM
Nvidia 8800 GTS 1gig
Checked CPU load during the game, it's only at %20.
Check GPU load, with something like MSI Afterburner. You'll probably see 98-99%.
That's a minimum-spec card(!) It'll do medium settings at reduced resolution, at frame rates in the 30's. It will have frame rate problems trying to do medium settings at full resolution.
