You prolly have Vsync on. Assuming your monitor has a refresh rate of 100htz at what ever resolution you are running.

The simple fact is how ever is that no matter what your FPS ocunter is showing, your game is not running faster than your refresh rate.

Your counter could say 200fps, but your refresh rate could only be 60htz, so you would get about 62fps no matter what your counter says.

With this you'll also experiance clipping. Thats when the walls look like they are moving apart, or certain textures are not moving smoothly with the rest of the textures. This is because your vid card is rendering more frames than your monitor can show, so your monitor misses a few frames.
