Kind of sad how the proprietor of DirectX owns one of the best Vulkan API game engine implementations in the industry.
It’d be telling if later iterations of idtech (should it continue to develop) switch away from Vulkan on desktops.
Would be a difficult move considering how ruthlessly performant it is at present.
It may be but the engine team is mostly Ex-Crytek folks carrying over from Carmack’s work with OpenGL. Even the Raytracing support is just a Vulkan Extension. They could change gears.
