People good with PCs

I could be wrong, but I believe that there's a single engine refresh per frame drawn. So the higher your FPS count is, the less mouse input lag you get (for high FPS players: try capping your FPS at 100 and then 1000 and you'll notice the difference).

Unfortunately, this is true.

However, what you can actually do (which I recommend and have done for ages) is to cap your framerate at a multiple of your monitor's refresh rate, so you get the same amount of visual change with each refresh cycle and there are no "half-frames" being drawn. For anyone saying they or others "hit better" with high FPS, they are wrong. The only difference is simply that your mouse is (much) more responsive with 200fps or more than if you were stuck at 60 fps.

This is a good idea. If you will actually detect a change is another matter completely.

EDIT: Also screen tearing is never as bad as Krayce's picture suggests.

Never as bad in one frame, but if you have it happening every other frame, it gets quite annoying.
