These metal implementations are constructs, and they are constructed differently for no good reason. Is there any benefit to anyone with all these proprietary implementations? Maybe, but if so, the beneficiary isn’t the consumer and it isn’t the game developer.

So who is the graphics hardware built for? Again, not the consumer and not the game developer.

It is in the interests of these hardware manufacturers to make performance as easy as possible but none of them do. They write their own drivers which implement DirectX 12 or Vulcan or Metal or OpenGL.

So now as a game developer, if I want my game to perform on all platforms, I have to write my shaders natively for Metal, Vulcan, and DirectX 12, at least. Cross-compilers exist but they don’t do their job as well as a human can, so they’re simply not options for some.

All of this is harder for no good reason. And no one cares. No one wants to see things improve. They just make excuses for the hardware manufacturers and kill conversations which explain how things currently suck for a lot of people.
