I dun' jitterd.

If you want to keep the smooth gameplay and not jitter, you can always leave vsync off and use dxtory to cap your FPS at something well below 180.

How do I turn vsync off? I downloaded Dxtory, capped FPS at 120, but it's still 60.

Why do you want it to be 120?

Try to download DXtory and cap fps at 120

Why not just Vsync on?

@ Cata: Higher FPS can eliminate the mouse lag, which shoudn't exist above 100 FPS.

Or maybe just try normal ways of getting rid of mouse lag no? By adjusting windows mouse settings?
