Less input lag with V-sync turned off... help!

Hi,

Why do I experience more input lag when I have V-sync turned on in the game? If I have it turned off, I cant notice the input lag at all.

I have tried forcing it on with triple buffering in the graphic card settings in windows turning it off in the game but it didnt seen to help.

Its clearly noticable playing online, but less noticeable offline.

Is there a way to fix this? Why is this happening?

VSync by its very nature creates input lag because it buffers pre-rendered frames… triple-buffering makes this even worse by buffering extra frames. You can use VSync with no added lag if your PC can run SF4 at 60+fps all the time, and you set your “prerendered frames” to 0 in the nvidia control panel (not sure if ATI has an equivalent).
