eli5: What does a GPU do when you play a game.
In: Technology
For your computer at home, games are harder to run fast than the other things you’re probably asking it to do. There’s a lot of math the computer does in the background trying to figure out where all the stuff in the game is and how it should look on your screen. If your computer can’t do all that math test enough, the game will run too slowly to play and it might not even run at all.
The GPU is an assistant that does all that extra math for your computer. It’s really good at doing geometry – calculating angles and stuff, which is the kind of math that games need. So it does as much of the extra math involved in figuring out what goes on the screen so the rest of the computer can keep doing the rest without getting overloaded.
