Answer 1

A frame in a video game must render in 0.017 seconds on a machine that costs $500.

A frame in a movie can render in as long as it takes, on a machine that cost tens or hundreds of thousands of dollars.

To get the video game output that fast for that cheap, enormous computational shortcuts have to occur and the motions and physics are greatly simplified.
