Actually our eyes do use frames, and even pixel-like structures. This is provable by the fact that when put under stress time seems to slow, this is our FPS essentially speeding up, to give us better control of the situation. And THAT is proven by an interesting experiment where people were dropped off a bungie jump structure, and were able to read an extra frame of time on a rapidly changing display more than they were able to see on the ground. Of course, when FPS increases in a game, the game seems to speed up. But that's because FPS in a game is realitive to the speed of the game, while real life time is not dependent on our perception of it. EDIT: But all that's off topic. Sorry.
