I like how people fail to understand that a 60hz screen can only show 60 images per second, and think i'm somwhow talking about how the eye can't see more than 60fps
Some facts:
-With a 60hz monitor you won't get a "smoother" image with over 60fps, only the game itself may run better, that's engine specific. (in minecraft you see and feel every fps more for example)
-The eye has no fps, it only won't see single pictures if the gap between them is small enough. (you all know a flicker book
)
-The "gap" gets normally small enough somewhere around 20fps, but that's not true for games, as they "work differently".
-Still some games seem completely smooth with 30fps already, again that's engine specific. (WoW is smooth for me at 30fps in capitals, LoL is not)
And most importantly: 60+fps on a 60hz screen looks shit:
