when you're used to play on 130-200 fps you will see 60fps as a lag, i remember i did with half life 2, when the fps reaches above the refresh rate the screen is running on then you will see tearing but it will look a lot more "smoother", its all up to you if you want the tearing or to have a constant 60fps.
It gets really choppy. Even portal for example
vsync off I get solid 300fps, screen tears
vsync on solid 60 fps , gun and game lags and is really choppy.
Is their a really good monitor I could get so I can play full fps and not have lag?
