%description
Stream VR games from your PC to your headset via Wi-Fi.

ALVR uses technologies like Asynchronous Timewarp and Fixed Foveated 
Rendering for a smoother experience. Most of the games that run on 
SteamVR or Oculus Software (using Revive) should work with ALVR.

ALVR is an open source remote VR display which allows using head mounted
displays (HMDs) via networking.
