Stutter in Bully on Wii/Dolphin

Hi all,

I want to play Bully SE on Dolphin since it's one of the best versions of the game. But I'm struggling with frametime stutter.

Settings I tested:

1. Dual Core Speedhack activated/deactivated
2. Enable MMU activated/deactivated
3. Enable Write Back Cache activated/deactivated
4. Override CPU Clock Speed -> 130-180% -> Lessens the frequency of frametime stutter a little bit
5. Video Backend: Vulkan vs OpenGL -> Stutter is identical but OpenGL has graphic/color issues.
6. Shader Compilation Mode -> Not relevant I think, because I have frametime stutter, not shader compilation stutter
7. Emulate disc speed -> game doesn't start when activated
8. Game ROM on SSD (PC) and internal/SD card storage on my Odin 3.
9. Odin 3 screen Hz is calibrated.

I tested these settings on 2 devices. My PC and my Odin 3. Both have identical issues.

Odin 3 Max
16GB RAM
Snapdragon 8 Elite
Adreno a830

PC:
Ryzen 7 5700x3D
32GB DDR4 3200mHz RAM
RTX 4080 Super

It's pretty heavy framtime stutter. From videos on youtube running the game on native hardware I gathered it runs much much better on a real Wii.

Did I miss some settings or is this game just not running well on Dolphin?

Any help is appreciated! :)
