Is it normal for Desktop Windows Manager to use a lot of GPU?

GTurbo 1 Reputation point

I believe my PC specs are still good... So I'm not sure why DWM.exe is such a resource hog. I've done a clean install of NVIDIA driver and updated my drivers several times but this seems pretty consistent. I'm just not sure if it should be using so much GPU, it seems like my games & programs run fine either way. Could this be a sign of an undetectable virus?
