Major slowdown in Fullscreen

[invelios]

For some reason, playing games in fullscreen causes major slowdown. I'm getting almost half the speeds I'm getting in windowed mode when I go fullscreen, even if I have the internal resolution set to the lowest value. I've tested this on both SMG and Monter Huter Tri, and it happens on both. Is there a reason I would be getting this slowdown just for using fullscreen mode?

What drivers are you using?

Catalysts until 12.6 have a clock stuck problem with HD7000 Series

I'm using the latest beta driver (12.7 I believe).

Here are my Dolphin Settings:

Disable full screen mode , use "Alt-tab" to switch to full screen
Edit : Typo , I meant "Alt-Enter"

Welp, that seemed to work. Thanks!
