I have a i7 2600k 8gb of ram a MSI twin frozr III Power Edition GTX570 the game runs max 30fps on max settings then gets worse and worse till I only run 1.7 fps then must restart my pc. I run Battlefield 3 on max settings at 55-60 fps and run Crysis 1 at max settings at 50-60 fps just fine so whats up with this mod? bad optimizing?
