Sonic and the Black Knight freezes constantly

[PTRGamer]

I have been playing the game for a while, and i finally succeeded in getting the performance around the 90-100% for most of the time. For some reason, the game still crashes every 2-10s, which kinda makes it unplayable. I have tried multiple solutions, but it didn't work. I'm using the latest beta build and almost every other game I play with dolphin works fine (80-100% performance) so why does this game not work? Might it have something to do with the fact that i converted the iso to a .rvz file?
Furthermore, when saving or loading savestates the game freezes for at least 15s which is also kinda annoying. Sometimes it even crashes dolphin. Any workaround for that issue?

Have you tried redumping your game? I would defiantly recommend trying the normal .iso format as well.
