You switched to DX9 plugin which is more likely, also framelimit on off or auto would provide stable gameplay. Yes dolphin can play any game just fine on 1080p resolution.
Use same resolution in game as in desktop. Don't use OpenGL. Panic handlers doesn't affect speed, it will just show the error message if you crash or encounter errors. Copy EFB to texture. With those settings you would already get full fps
