I've tested Puter on Oculus, seems to work pretty well; however, I think very soon I'm going to do very specific optimizations for XR, it's a new, emerging form factor that deserves its own design.
I don't mean in a browser on a VR headset, I mean on a texture on a game asset in a Unity scene in a Webxr space in a browser on a headset.
This way you have the experience of sitting in front of your computer while wearing a VR headset anywhere in the world.
