Nice story, except DirectX owns the PC market, period.
pjmlp I have been on this forum long enough to know you would eventually move the goalposts. Your claim was about the merit of extensions, I'm not sure why you're talking about marketshare now.
If you want to target PC, you have to deal with hardware fragmentation. You can pretend this is a Vulkan issue, but it's just a reality of the platform.
