You forgot to post a face picture.
This isn't 4chan, you idiots, so stop trying to >greentext shit or use mfw or tfw. You look retarded.
On-topic: It varies from human to human. Some can't see the difference past 24 fps, some can see the difference with 100 fps.
In games it's a bit different, because they don't use motion blur, every frame is played instead. Pause a movie and pause a game: the movie screen will be blurry and the game screen will be not (depends on what you were doing though).
But honestly, no need for it to be above 50 fps.
