The M3+ GPU is also very different. So while it may be true that the driver development for M1/M2 is now more or less complete as OP says, future work along the same lines will very much be needed.

- ykl 1y agoThis is a pretty well known thing; the M3/A17 generation GPU was a ground-up redesign that added things like dynamic caching and hardware ray tracing [1] which are highly nontrivial to simply extend an existing architecture to support. Unfortunately I can’t find where I read this, but IIRC at the time M2 came out there were expectations that M2 would have a new GPU architecture with hardware ray tracing but this wound up being delayed to M3 because it took longer than expected to do a ground-up redesign of the GPU.
