and TURN OFF VSYNC, although it's only supposed to limit fps to the refresh rate it's been known to be a little screwy and you'll often see an immediate 20+ fps jump as soon as you turn it off, you can make sure it's off by watching the fps during title screens (where no 3d scenes are being rendered) the fps can reach into the hundreds and thousands, with vsync on it will stay at 60

This may help clarify what vsync does and doesn't do.

Tearing
It is an unfortunate fact of computer graphics that if you disable VSync, your graphics card and monitor will go out of synch. Whenever your FPS exceeds the refresh rate (e.g. 120 FPS on a 60Hz screen), or in general at any point during which your graphics card is working faster than your monitor, the graphics card produces more frames in the frame buffer than the monitor can actually display at any one time, so the end result is that when the monitor goes to get a new frame from the primary buffer of the graphics card during VBI, the frame may be made up of two or more different frames overlapping each other. This results in the onscreen image appearing to be slightly out of alignment or 'torn' in parts whenever there is any movement - and thus it is referred to as Tearing.
