This is more exciting for me than 3d. I remember thinking this when I first noticed that counterstrike didn't feel right at <60fps while watching action films with 24fps
That is because a game's frame is rendered at one absolute time point, while a movie's frame is like a photograph taken with a shutter speed of 1/24th: it includes the motion data of that whole time interval, it contains motion blur, and it's smooth from one frame to the next. That's why a game at 24fps looks bad, but an (action) movie at 24fps looks good.
"Looks good"? Maybe passable. And that's only because of a century of experimentation with camera techniques allowing to eschew the limitations of the format.
E.g. try giving an amateur a 24 fps camera and ask them to shoot a sequence that involves a lot of panning. The result is going to look like junk.
Even in the hands of a professional it still doesn't look good. But we've all trained our brains to shut up and accept it, because we've all watched so much 24 fps content. It's 100% pavlovian conditioning, nothing else.
To someone coming from a universe where all motion pictures are shot at 60 fps or above, our movies would look excruciatingly bad.
