If a computer is powerful enough, how does it know not to play videos or perform logic for games at a faster speed?

Question

I don’t know if I’m explaining this right…
A computer can run logic at some speed based on how powerful the components of it are, so if it can perform the logic of something, for example, movement in a game, how does it know how much should be done based on its power, instead of essentially running in “fast-forward” or conversely in slow motion?

Computers have a clock that, surprise, measures time. Older games often didn’t implement time checks and used to run as fast as the cpu could cycle. Nowadays, every frame is rendered against a ‘delta’ variable that’s basically the time difference from the previous one
