The game runs fine on my secondary machine. I get like 40FPS with the settings on high on 1024x768. Im running a AMD Athlon XP 1600+, 1GB PC2100 RAM, GeForce4 Ti4200 with AGP 8x on a Gigabyte GA-7VAX-A Motherboard. My main machine gets about 60 FPS with alot of peeps around but its an Athlon XP 3000+, 1.5GB PC3700 RAM and an ATI Radeon 9800PRO 256MB on the same board as the other machine. If people are having performance problems and they are running a better system then my secondary one, they must be doing something really wrong. I think the game just frustrated them so much they are exagerating on how it runs. I havent enountered a bug or problem in this game in the last 3 days.
