I won't accept my pasta at anything lower than 120Hz.

The human eye cannot see more than 24Hz, so why bother

I don't understand the basis of the 24Hz limit rumor. My monitors are 144Hz, and if I limit them to 60Hz and move my mouse around I see fewer residual mouse cursors "after-images" than I do at 144Hz. That's a simplified test that shows that the eye can perceive motion artifacts beyond 60Hz.

The eye can perceive LEDs that are rectified at 60Hz AC, it's very annoying.

Your eyes are not digital. Nothing physical really is. Think about a camera flash. They can get well under 3.33ms, meaning over 300fps, and you can still see it clearly (and painfully). Same for a monitor, it also has a "response time". It is how long it takes for a pixel to transition color. (Usually "gray to gray", as in one shade of gray to another. Black to white would be longer, as is for eyes.)

So ofc you would see all the mice.

It's also why motion blur is a thing, even though it was usually implemented incorrectly. Seeing every motion on a tv or monitor in perfect sharpness feels weird, because they are pictures not actual movements.

Your brain makes movements out of it all.

Anyway: 16 is minimum, 24 is good for most movies, 30 for slower games, 60 minimum for fps (75 and above for faster fps, even though i played xonotic on 45), 120 for vr.
