While I was incorrect about id Tech (and have edited my comment), I never made the point that any of the other engines didn't target Vulkan. Where else is my comment untrue?

I am confident in my assessment that the large majority of existing implementations are still running OpenGL and/or Direct3D, if on Windows.
