I believe 24Hz works in movies because the way cinemas are set up. The image projected onto canvas in a dark/dim room “burn” in (not sure what the correct term is) which can make it appear smoother. This is why they can get away with it in cinemas. Plus it’s also a consistent 24Hz, which in games (and Way of Water) isn’t.
People used this excuse for games, to make games more “cinematic”, but that was just an absolute horseshit excuse for games being poorly optimised. Especially if the framerate wasn’t locked to 24FPS, and because home monitors and TVs don’t work the same as cinema projectors.
I’m sure if all cinemas and media would move to a higher framerate/Hz it would eventually just feel normal though. It just often takes a lot of time getting used to, especially for cinema experiences.
It’s often weird how people don’t notice it much when you turn a setting on or off. But then I usually whip out the UFO site and they’re immediately convinced (it’s also easier to explain).
I have to say that on the PS5 the framerate differences have been quite noticeable. Especially first-party titles that support performance mode to go up to 60+ FPS instead of a usually locked 30, like in God of War and Horizon games.
