Some more progress with Mario 64 on the EOS R5
The camera has a GPU hidden away with OpenGL.
Software rendering is out. Mario is now rendering on the GPU which means the Nintendo 64 of cameras just got a significant hardware bump. The previous version ran only in software (ARM CPUs), the GPU version looks identical at the moment but with much more headroom to go gangbusters on frame rate, resolution and 3D rendering techniques.
It would wind up being useful for photography and filmmaking apps if it had OpenGL general compute capabilities, still exploring that bit.
Meanwhile I have my film emulation app that started on the 5D Mark II working on the EOS R5 (and soon R8). They are beasts of a camera, let's hope it doesn't over heat
