Swager if you cap out at 60 fps and don't have the framerate cap on, check your monitor refresh rate IN game...
If you use Windows2000 you NEED a prog called nvreffix to set your in-game refresh rate higher. This is due to a bug in nvidia drivers, the desktop refresh rate is not transmitted to 3d like it should!
You can choose from 60hz to whatever your monitor supports. Usually it's possible to play 1024x768 with at least 85hz. I would not suggest playing with anything less than 75hz refresh because that really kills the eyes.
