It seems (wasn't really that clear?) that Maya was running emulation? (as in, x64 binary). I don't think Maya's viewport on MacOS actually runs with Metal (it's still OpenGL), so I doubt it's a native port.
Did it do any CPU-intensive stuff (skinning, deformation), or was it just GPU-intensive viewing?
High-end VFX will be interesting for this with Apple (Maya, Houdini, Nuke) - already there was quite a lot of anger at OpenGL being deprecated and Vulcan not being officially supported. Another instruction set into the mix for highly-optimised apps (lots of SIMD code) is going to be quite annoying, especially for the CPU renderers (Arnold, Renderman, etc)...
As Apple's own GPUs do not run full OpenGL, does this in turn mean they didn't only create a x86 to ARM translation layer but also a full OpenGL implementation running on top of Metal? Similar to other projects implementing OpenGL on top of Vulkan? Or did they actually invest the time to implement OpenGL directly in their graphics drivers?
That seems a bit weird considering OpenGL has been deprecated in macOS already. I would have expected a full removal once the first ARM Macs ship.
