Whats the point of more than 36 Fps?

[Kaynin]

specifically while fast turning, the eye can see up to 100, perhaps even more for the individual here and there.

It's still a minor increase tho and the difference would hardly be noticable, but if you can get 100ish fps, try it out and turn fast in wow. I'm positive you should see the difference. (I do!)

But is it needed? Nah. :P 20ish FPS is already playable enough really.

As pointed out already, eyes (and brains) don't process all at the same speed, so there is no magical perfect FPS number for all humans. People also claim to see a difference all the way up to 120 MHz, which is only kind of true.

To explain as simply as I can, if you're not processing the images at the same exact frequency as they are being presented, then you will notice disparity. If you process images at 30 FPS, and they are generated at 34 FPS, then you're going to be processing more transitional images (one image morphing into the next) than clean images. Your eye is taking a "snapshot" of what you see more often at times when the image is in the process of changing to the next one, because you're not perfectly synched up with the rate they are delivered.

Higher FPS means the transitions from one image to the next happen much faster, and less likely to be caught by the eye. So, in theory, there is no FPS threshold that can be claimed to be perfect. But there's theoretical thresholds where you'll stop seeing any difference at all (which will be somewhere in the hundreds if not thousands of MHz).

I'm not a video editor or a film maker, but I can tell you this. 9 years ago, when Quake Deathmatch was all the rage, I was initially averaging about 30 frames per second. I had a "slower" machine at the time. A full rebuild about a year later yielded no less than 60 frames per second. Wow, what a difference. My response time improved, my scores improved... it was like night and day.

So from that alone I can say this:

There is a noticeable difference, improving frame rate beyond 30, at least until 60.

Though I can't say about going above 60... while you are less likely to bottom out to a noticeable frame rate if you are running higher than 60 (120? higher?) you probably wont notice any actual improvement while you are up that high.
