I find that interesting and I'm sure anyone attempting celestial navigation will also, since that does affect them also... sadly, the days of the DirectX v9.0c games are coming to an end... everybody wants an FPS instead of fps... sorry, bad pun...
From what you describe with your new card though, it seems that the anti-lag utility and the nVidia inspector both use a "multiplier" instead of actually limiting the frame rate. On this laptop I'm on right now, a 40Hz driver, with anti-lag set to "30fps" actually yields about 24-25fps, whereas with it set to 60Hz, I do get 30fps...
- math... sheesh! Not my strong suite.
