Microsoft has begun testing a new version of its Xbox program for Windows with support for mobile devices
What else is known
Although now the Xbox App will be up and runningon ARM devices, but gaming is another matter entirely. Games that have native support for ARM like a cat cried, so you have to use the built-in compiler, which can cause problems with performance or with games in general. As an alternative, it is possible to stream games from cloud services like Cloud Gaming, which also now works on Windows devices with ARM.
