Has vr ever worked with New Vegas? I don't have the equipment myself so I'm just curious.

With VORPX it works, here's a recent video that gives a full rundown on how it performs. https://www.youtube.com/watch?v=8Mo7ET7pFj4
Head movement is tied to aiming which makes it a pain. If there was a mod that would make New Vegas work as well in VR as Fallout 4 I'd buy a VR headset ASAP.
