Lol, I'm getting like 50fps windowed. What I'm saying is the human eye sees at 24 or so fps, so having more is completely loving useless.
That is simply not true; our ability to perceive the changes in an image varies from person to person, just as our perceptions of taste, sound, and color can vary. Gender, ethnicity, age, and a variety of other factors can affect our ability to notice certain effects. An example of this is the "mosquito ringtone", a sound whose frequency simply can't be heard by most adults, but can easily annoy younger people whose ears are still sensitive enough to hear it.
Thus whilst 24 FPS may be sufficient for some people, others do notice the difference and find that a higher FPS is more desirable (or necessary) for enjoyment.
