"Please temper your expectations: even with hardware documentation, an optimized Vulkan driver stack (with enough features to layer OpenGL 4.6 with Zink) requires many years of full time work. At least for now, nobody is working on this driver full time3. Reverse-engineering slows the process considerably. We won’t be playing AAA games any time soon." From https://rosenzweig.io/blog/asahi-gpu-part-6.html
Totally non-sarcastic question: then why bother? It's an honest question. Even if someone (or a team) could somehow be paid for this work, by the time the results are usable, the hardware will be more or less functionally obsolete. And that is on top of the fact that ARM64 on MacOS will always be a small slice of the gaming pie, and ARM64 on Linux games and GPU applications virtually nonexistent.
