Dolphin runs like a <slur>, why?

[Carsomyr]

I LOVED Star Wars: Rogue Squadron on the N64, and then 2 and 3 on the cube. In trying to play both of those again here on dolphin, I am running into all sorts of problems. I get a lot of opcode errors, or dolphin stops working and needs to close, or when it runs it just generally runs horribly. Changing backends and audio configuration has no effect. For giggles I ran GPUZ alongside Dolphin:

Can someone explain to me why my GPU is essentially idling while Dolphin is running? And then also why these 2 games have an incessant need to crash?

And until I can figure out why there is nowhere to create my sig in user cp....
