It's better to download it from the Oculus store, the windows store version just installed the 3d/2d version so i had to install it again for 3d/3d.
Available on the GearVR and Rift (and DK2) .. hopefully the Vive will follow.
I can't speak for windows 7 or pirated copies of either. I can say, it's bloody brilliant, no ghosting or latency or lag of any kind. truly immersive.
I think MS are trying to cash in on texture packs but im sure there will be a way around that if there isn't already.
