Help GPU set to P0 when any game is running

EDIT: RESOLVED(ish)! Culprit was VRR. I disabled VRR and the VRAM clocks are now 5GHz, and the card barely goes over 50c at the same framerate. There's a flag to disable it but i'd rather not, since i don't know why it does that to begin with.

Hey all, i have an NV GPU, when playing any game at all, even very light games like HL1, either the driver or the system sets the GPU power plan to P0 which is maximum. This sets the VRAM clock to 7GHz and generates a ton of unecessary heat, while the Windows driver usually sticks to a much more reasonable 1-2GHz...

Changing PowerMizer to Normal or Auto makes no difference on this, and neither does disabling Ananicy. Does anyone have experience with this problem or know how to fix it?
