120Hz monitors are a great step for LCD to catch up with CRT in regards to motion blur, but I must say I am disappointed with software support (60fps or 30fps capped
PC games), to the point that I regret my purchase, I think I should have purchased a good 60Hz IPS and purchase a 120Hz monitor later.
60fps looks terrible on my XL2411T - try playing Bit Trip Runner and you will see what I mean, it creates terrible "frame doubling" issues.
There are workarounds (namely forcing lightboost) but this is not standard at all to this day and only work with specific hardware.
=> what about a 120fps games and tweaks list ?
So far I could only find
that one, which is fairly old and incomplete.
@Water: you may want to completely disable the default motion blur in L4D, it makes 120fps less noticeable.
