Thats good. I kinda got depressed after playing bioshock lol.
If it's stuck at 60 fps, crank it up more. You're can eye sees images at about 32 fps (at it's sharpest of something).
Man I don't have the "high" I used to get playing games anymore (anyone understand). Now if I play a game I don't mind, but if I don't play, I don't mind too. I'm not enthusiastic about them as much as I used too. I don't know why.
Edit: you're telling me that will run good on a 6600gt? (I just saw the pic)
