My dad told me to look into something called "parallel computing" but I don't really understand what it is or how to put it into practice.

I have a raspberry pi 4, and two windows computers.

I can wipe the raspberry pi and one windows computer, but I am looking to run games (that can't currently run with just the one computer) on the other windows computer.

I apologize if I'm being dumb, I don't know as much about computers as I'd like.
