Only the view mask is used as input, and since we do not use MultiView, it is always 0

I'm assuming MultiView refers to VK_KHR_multiview. Does DirectX 11 have anything similar that would benefit VR performance via multiview? All I can find is OpenGL's version and view instancing in DirectX 12 (allegedly benefits single pass VR rendering but I don't see mention of VR in documentation)

Recently NVK gained support for multiview. RADV also supports it. Not sure about Nvidia's proprietary drivers.

D3D11 does not support Multiview, no. There's vendor extensions for it, but they are poorly documented and incompatible with each other as well as with how Multiview works in Vulkan, so we don't have any plans to support that.

Not sure if the average VR game even uses those.

Thanks! Sounds like it's more for games built for the Quest and other standalone systems that use Vulkan.

Nothing extracted yet.
