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?

Answer 1

Because the computer has a clock that runs at a set speed independent of the processor.

This wasn’t always the case, some older software and video games did time their actions based on the processing speed, so if the software was ran on a faster computer then the game would also appear sped up.
