Movies always get brought up in framerate discussions but they are a completely different beast compared to interactive computer applications because

a) movies are not interactive so latency is not a concern, only fluidity is

b) movies come with pre-applied motion blurring to hide the low framerate (which is different from fake motion blur applied in some games)

c) 30 FPS is atrocious even for movies and I wish higher framerate movies had gotten more common

30 vs 45 fps on my steam deck feels night and day different, it's amazing how much small jumps like that can help.
