Dolphin has up to version ~3.2, and glPatchParameteri (and tessellation shaders) come with 4.0. But the Dolphin's OpenGL headers don't have glPatchParameteri.It's often very difficult to generate a complete cache for large games, and will not completely eliminate stuttering. You can go to /r/Cemucaches and search for the ones you want. Cemu accepts other shader caches that can be traded online. This can cause a lot of stutters and slow the game down. Shaders are normally cached as you play the game.
