My integrated and dedicated GPUs is fluctuating in-game now. FPS is shit and this is a relatively new issue. It'll do this when I'm hosting raids, with more fluctuations when there are more people in the party and less when the party is smaller. It seems to have stopped fluctuating when I'm not the host or when I'm in town, for the most part. It also fluctuates when it's not in use (only integrated). Not sure what is wong.

When hosting a full 8-person party:

Dedicated GPU fluctuates between different values 450-835 MHz (hosting 8-person party). The end shows 135 MHz because I alt tabbed, so it wasn't in use.
