Google Cardboard has made it so that even videos that aren’t designed for virtual reality can be viewed in virtual reality as a sort of simulated cinematic experience, and now Valve wants to do the same thing for video games. The company teased this new feature, called SteamVR Desktop Theater Mode, on Saturday, saying that it’s currently in early beta, but didn’t go into further detail. Naturally, the feature will support the Vive virtual reality headset that Valve developed with HTC, and will support other headsets as well, but Valve didn’t name any specific ones. It’s safe to assume the Oculus Rift will be one of the supported headsets, though.
