When I first started emulating wind waker (gamecube) in dolphin this morning, it ran extremely well at 30 fps. Then I started messing with some of the graphical settings, and the game ran even better. Then I tried using save states, and the game got really choppy and has stayed like that ever since. I uninstalled and reinstalled dolphin and got a new ROM, and it still runs terribly. I checked DSP HLE which did take out the choppiness, but it still runs around 18 fps. Thanks in advance.

Just fixed my own problem lol! It seems my laptop runs in a power saving mode once you unplug it, so that was the problem (just got this laptop so I didn't know). Feel free to delete this if you want, I'll leave it up in case it will help someone else.
