Nah, I'm running on metal, no VM. I doubt this is something in your game code (like the collision shapes issue you mentioned). Like I said, for some reason there's no GPU usage at all, the game process isn't even mentioned in nvidia-smi. I had something similar to this when I had mistakenly deleted all 32-bit nvidia libraries and turned out everything in steam is 32 bit. But your executable is clearly 64 bit, and I've got that issue sorted out in any case.
Anyways, if there was anything I can test for you in Linux do throw me a message. I'll do my best to help. Otherwise, I hope you enjoy the jam as much as I am right now!
