ALVR - Air Light VR

ALVR is an open source remote VR display for Gear VR and Oculus Go. With it, you can play SteamVR games in your standalone headset.

English | Japanese

Description

ALVR streams VR display output from your PC to Gear VR / Oculus Go via Wi-Fi. This is similar to Riftcat or Trinus VR, but our purpose is optimization for Gear VR. ALVR provides smooth head-tracking compared to other apps in a Wi-Fi environment using Asynchronous Timewarp.

Now, we have Gear VR / Oculus Go Controller support!

Note that many PCVR games require 6DoF controller or multiple buttons, so you might not able to play those games. You can find playable games in List of tested VR games and experiences.

I have started crowdfunding about support for AMD GPU on this page. Also refer issue #33.
