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.
Idk man. Cloud and air efficiency seems higher, even with the added propeler and magnetism step in there. Then again lost panel energy goes into air.
