So go into the game and try this.. disable vsync but when it asks click no and see it if that doesn't boost your fps by about 10-30. I got some screens of my stock i7 2600k with gtx 570 sli doing 75-99 fps with vsync on. Also a slight over clock from 732 to 785, mem 1950. It won't do this unless I do what I just said, other wise it sits right at 60-59 ish.
Man I hate to be a conspiracy theorist but... I hope cyrtek and nvidia arent messings with ppl's systems.. and making it appear to run better or worse for sales sake.
