Sometimes while playing a game or something like that I'll look at how my computer is running and it tells me that my CPU is running at 100%. Sometimes it will only tell me a couple of percent. What's with this?
That's your CPU usage percentage. The more you have running, the more load on the CPU, the higher the CPU usage percentage. Depending on what you have running at the time, it can vary from 1% or 2% to 100%.
I know what it is, my problem is that it'll tell me I'm running 100% for a game and then like 2-3 a minute later. I donj't think it should be making drastc changes like that while running one game.
