One thing that's MIA is talk about VR specific features. Looks like NV is going to be the leader in that department.
DirectX12 came to live for VR. You do not need any specific features, unless your hardware lacks compatibility with DX12 features, to run VR games.
Vulkan and DirectX12 are VR APIs. Remember this. That is all what they came to life for.
