So I was playing Super Paper Mario, and I changed the Graphics Settings. Then I switched my game to Mario Kart Wii, and it worked fine. But once I selected "1 Player", it slowed down to about 7 FPS and wouldn't go back to normal no matter what I did. Can someone please help?
What are your computer specs (you didn't give enough details), have you tried the latest development version of dolphin?
So I'm running Dolphin 5.0 on my Mac, and Mario Kart Wii worked fine. Only when I changed the graphics setting it started to slow down. I've even tried the latest development version of dolphin, and the result got was a black screen. And I also found out that Mario Kart Double Dash wouldn't work either.
Never mind, I fixed it by reseting all Dolphin settings to default.
