Would 60fps give the same visual quality of a human eye, if that makes sense?
It would be pretty difficult to estimate the eye's function in terms of FPS, since that's not how it operates at all. If I was pressed about it, I would say that the human eye is capable of seeing in excess of 90 fps, probably up to the 200 fps mark or beyond. The brain is very, very fast. More frames would always be smoother and better, but 60-90 seems to work fine with our present technology.
