Donkey Kong Country Returns major stutters
Donkey Kong Country Returns
What's the problem? Describe what went wrong.
When I play this game, I get some major stutters in random intervals, although never back to back. I'm pretty sure that they aren't shader related, I used skip drawing and they still occurred. I also deleted the shader cache to see the shader gen stutter and they are very minor and don't come close to the random major stutters which last about 0.6 seconds.
I've tested OpenGL, DX11 and DX12 and all showed the same behavior. I also tested in single core and with gecko codes disabled and default settings.
I haven't found anything that triggers it but I think I get the stutter on average every 7 or so minutes and usually once per level but sometimes I play for 15 minutes without any stutters.
I've had this issue since I use Dolphin (1 year know I think) but never bothered to report it because it is not that game breaking or annoying.
What steps will reproduce the problem?
I get the stutter every 7 minutes on average by just playing the game.
Is the issue present in the latest development version? For future reference, please also write down the version number of the latest development version.
Is the issue present in the latest stable version?
Yes, although it seemed to be less. Hard to know due to the random nature of the issue.

Probably JIT code cache flushing. Enable the PowerPC log category and see if you get a message about that when the stutter occurs.
Yep, seems to be JIT cache flushing: core\powerpc\jit64\jit.cpp:737 W[PowerPC]: flushing main code cache, please report if this happens a lot
