\ development could have looked like if it was a backwards compatible hardware architecture instead of an API compatible driver world.
X86 bucked conventional wisdom about committing to an imperfect instruction set limiting performance; interesting to consider what GPU \

though this seems somewhat analogous to how HW vendors handle DX byte code, itself like a backwards compatible ISA

IMO part of the problem here is that a huge hole has been dug: too many features, all conflicting

and the fact that performance on PC is, for many applications (not VR!) "solved", trades get different values.

Don't think NVIDIA/AMD/Intel would ever settle on common GPU instruction set.

x86 changed instruction set and embedded internal registers all the time. The instruction set is a minor part of GPUs.

Ouch. I'm alternate-history-ing here, not making an actual engineering suggestion. :-)

With Moore's Law dying will get a clean slate CPU design that tries optimizing for gains instead of shrinking the die?
