So what does my CPU do when I'm running a game?

I would like to know what my processor actually does when the game is on. I mean what things does it do?

For example I would like to know what it manages and runs like AI and such.

There is no single answer.

Every game is coded differently.

Well, I don't know about your CPU, but I can tell you that mine does close to nothing when I'm running a game. It's always at like 15% or 20%, but I guess that's what happens when you have an i7-920. It doesn't have to work hard to get the job done.:P

This.

I went from a Core 2 Duo system to a Core i7 930 system but kept the same graphics card and in some games like GTA:IV, ArmA 2 and Supreme Commander the gains are huge but in others it's less noticeable.

It does everything to make the game work outside of graphics, and maybe sound (depends if the game processes sound off of the CPU or separate audio processor).

Sounds like all the GPU's doing is rendering what we see on the screen.psx_warrior

Thanks for explaining this everyone :)

Open your task manager where it shows the CPU % usage.

Now open a browser window and find a website to scroll through.

Now scroll up and down really fast. Keep repeating this and look at the CPU usage results while doing this.
