High refresh rate makes people feel sick. It's "too real", such that the brain can't synchronize what it's seeing to what it's feeling motion wise. Ultimately a 2d plane is not optimal for a realistic experience. By it's very nature, film is impressionist.

Do you have a citation for that? Lots of people play video games on big screens for hours at a time and don’t get motion sickness.

There were lots of reports of this with the hobbit, e.g. https://theweek.com/articles/469863/why-isthe-hobbit-making-....

Being on a big screen probably makes it much worse.

Also I’d conjecture video games are different. It’s like driving a car. Since you are directly controlling the camera usually, I think this helps your brain avoid nausea. Although there’s plenty of people who can’t play FPS either because it makes them feel sick.

Those reports were about the imax version though, and I have personally seen that happen in imax theaters showing 24fps content. That’s field of view, not framerate.

People who play games typically don't typically feel sick during cutscenes, even long ones, even when they're running at 60/120/144 FPS.

Sorry, but my personal experience with motion sickness and games says it's triggered by too-low framerates. Early 2000s laptops were particularly unbearable.
