Is it true that if you max out the GPU part of an Intel processor at the

other place this could happen is a game that multithreads on all the
cores and also uses the graphics.

Are you using a standalone GPU? If not, the CPU will be used to do
on-board/in-chip graphics.

On two of the machines, yes I have a standalone GPU. Two don't. And one has no GPU whatsoever (no monitor just a server).

I know the CPU is used to do graphics, but I'm interested in why it refuses to do that and all the main cores at once without one of the tasks slowing down. It's not overheating.
