Valve's new VR headset, Steam Frame, can play games in various ways, including streaming PC VR games, emulating PC VR games on its own Arm-chip, or playing native Arm games in the form of .apk files. There is a possibility that if you purchase a game for your gaming PC, you may also be offered the .apk version for free to use on the Steam Frame. The addition of OpenXR support may make it easier to get virtual reality games working on different devices.
