DX12 is less and less the default, most gamedev that I’ve seen is surrounding Vulkan now.

DX12 worked decently better than openGL before, and all the gamedevs had windows, and it was required for xbox… but now those things are less and less true.

The playstation was always “odd-man-out” when it came to graphics processing, and we used a lot of shims, but then Stadia came along and was a proper linux, so we rewrote a huge amount of our render to be better behaved for Vulkan.

All subsequent games on that engine have thus had a vulkan friendly renderer by default, that is implemented cleaner than the DX12 one, and works natively pretty much everywhere. So its the new default.
