Between XBox, PSVR and AMD GPU users, I don't see FDev investing the resources to cater to niche group of a niche group of users for NVidia on VR. If they have spare funding for graphics resources they'll spend it on the myriad improvements which could be made to support the entire user base e.g. fix rotating smoke, space legs or something above the Honker to show how many times I honked this system already.
That said, if they did it, I'd have so much fun discovering the benefits to my display settings.
