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

Answer: computers follow instructions regardless of their techno-horsepower. An internal clock is running, and the instruction set dictates the pace of play. Many old emulators come with ‘hyperspeed’ or whatever they wanna call it, but it plays the instructions at 2x, 3x, or even 4x speed. It’s not the processing power that determines the speed, it’s the instructions (which are often set to an internal clock)
