You're welcome Aniuk.
Not that I really did anyting.
Playing games at 60fps or higher also gives you a bit of a buffer for framedrop without introducing stuttering. Say you're playing a first person game and you're getting low 30s fps. You quickly turn around, the video card quickly needs to render an entire new scene and the fps drops. Not always desirable.
Just that little bit extra can make sure it's smooth all the way. fps above 60 won't make any visual difference, but it can smooth out the general experience.
Personally I can't resist cranking up the quality. I don't play games where that "super-silky-smooth" stuff is needed anyway. (like a first person shooter)
