On the contrary, if you ask a random person how fast the fps needs to be before it doesn’t really matter, the vast majority will say either 60 (because that’s usually the cap) or 24 (because it’s what movies use).

If it wasn’t generally accepted, the world wouldn’t use it in well over 9 out of 10 cases.

You’re correct that the rest of my comment was mistaken; see the sibling comment that presents a paper from nearly a century ago showing that humans can perceive up to 2,000 Hz.

60 comes from the electrical grid - 20th century TV used the electrical grid to sync rather than forcing every TV to have a perfectly synced clock. Regions that didn't have 60Hz electrical grids used other standard framerates.

24 comes from the first "talkies" that had syncronized sound - it was the lowest framerate that sounded good. Before that, silent films were often at lower framerates to reduce the cost of film.

This is driven by standardization, not any kind of human perception limit.

Doesnt matter for enjoyment of a product Vs is some sort of threshold of noticeability are very different.
