I'm bumping this because I'm having the exact same problem and it started for no apparent reason. I downloaded Dolphin 2 days ago, played MarioKart Wii for atleast 4-5 hours with no problems. I set the graphics settings to the best possible for my rig and get above 60fps. Yesterday I changed some settings like using the JitIL experimental recompiler, however I've since restored all my settings to what was working 2 days ago. I do have a Nvidia 275GTX however, and it seems to be a consistant theme amongst people with this problem. I use DirectX because OpenGL does not run fast enough or at all.
Anyone come up with a solution to this, I see above a link to another thread which did not help me at all.
