To be honest the only game I have tried is Legend of Zelda: Wind Waker. During the display of the Nintendo/Dolby logos I get 60 fps, but at the title screen it drops to about 15-17 fps. Then at the file select screen it hops back up to 50-57 fps. Finally, in-game I get a measly 7-10 fps. I have attached a System Information Report taken from Advanced System Cares System Information utility. Hope it helps. If you need a screen of my settings within Dolphin let me know I will attach one a.s.a.p. Thanks in advance for any help you may be able to provide
