70 fps? Is that with 2x AA or 4x AA. I run the game with Vsync on but run the timedemo with it off. If its 4xAA, then I'd be very happy. If its 2xAA, it could still be a little higher. Have you tried using Catalyst AI? Also, depending on your hard drive, you could have to run it a second time to get your real results. Run it once, and run it again without exiting the game, and tell me what you get on it the second time.
