This is the sort of thing that to me highlights the inherent inefficiency of proprietary software and processes.

"Oh sorry, you'll need our magic hardware in order to run this software. It simply can't happen any other way."

Turns out that wasnt true which of course it isn't.

Imagine instead of everyone could have been working together on a fully open graphics compute stack. Sure, optimize it for the hardware you sell, why not, but then it's up to the "best" product instead of the one with the magic software juice.
