So, in a nutshell:
The few GameCube games I have for testing are happy up to 6x/4K resolution with all other settings at default. I believe they should be fine with 7x and 8x resolution, I just didn't test them.
Setting SyncOnSkipIdle = False, Rogue Squadron 2 keeps a steady 60fps even on Hoth. Although it does get hiccups occasionally when compiling shaders but is a lot better with transitions/cutscenes. I haven't tried the Death Star II missions yet, if it gets that same level of performance I have serious doubts my reflexes could keep up.
Rogue Squadron 3 is impressive to say the least. SyncOnSkipIdle = False and turn off Synchronize GPU Thread definitely brings speed improvements on the M1. With this, Revenge of the Empire bumps up to 20-30 FPS w/ 50-60 fps on the cutscenes. Once you start getting into later stages you get between 40-50 FPS on actual gameplay. The downside is that you will have trouble with CPU & GPU out of sync crashes on some stages.
Wii games seem to have a sweet spot between 3x/1080p and 4x/1440p with all other settings at default. With tweaking possibly could hit 5x native resolution, but I think 6x/4K would be pushing things too much currently.
