ALVR - Air Light VR

Badge-Discord

Stream VR games from your PC to your Oculus Quest via Wi-FI.
ALVR uses technologies like Asynchronous Timewarp and Fixed Foveated Rendering for a smoother experience.
All games that work with an Oculus Rift (s) should work with ALVR.
This is a fork of ALVR that works only with Oculus Quest.

  • High-end gaming PC
    • Windows 10 May 2020 update is recommended. If you are on an older version, you need to install Chrome or another Chromium based browser.
    • Minimum supported OS version is Windows 8.
    • NVIDIA GPU that supports NVENC (Supported GPUs) (or with an AMD GPU that supports AMF VCE) with the latest driver.
    • Laptops with an onboard (Intel HD, AMD iGPU) and an additional dedicated GPU (NVidia GTX/RTX, AMD HD/R5/R7): you should assign the dedicated GPU or "high performance graphics adapter" to the applications ALVR, SteamVR for best performance and compatibility. (NVidia: Nvidia control panel->3d settings->application settings; AMD: similiar way)
  • 802.11ac wireless or ethernet wired connection
    • It is recommended to use 802.11ac for the headset and ethernet for PC
    • You need to connect both the PC and the headset to same router (or use a routed connection as described here)

Install

Please uninstall any other VR streaming software on your PC. This includes versions of ALVR prior to v12.0.

If you didn't already, install SteamVR, launch it and then close it (this is to make sure SteamVR executes its first time setup).

Install the latest Visual C++ Redistrubutable x64 package. Do this every time you install a new ALVR version!

To install ALVR download alvr_server_windows.zip from the releases page, unzip it and launch ALVR.exe (the folder path must contain only UTF-8 characters and must be editable with user privileges). The first time you open ALVR.exe you may have to allow it in the SmartScreen prompt and allow the network access to alvr_web_server in another popup window (it could be behind the actual ALVR window).
It's important not to move the folder after the first launch. To keep settings from a previous installation of ALVR (>=v12.0) you can unzip over the old installation folder.

Install the client on your headset through SideQuest.

To make the Oculus Quest microphone work you need to install the VB-CABLE Virtual Audio Device.

Usage

  • Launch ALVR.exe (ALVR dashboard). The first time a setup wizard will guide you through the installation.
  • Launch ALVR on your headset. While the headset screen is on, click Trust next to the client entry (on the PC) to start streaming.
  • If you trusted a client, you can start streaming by just launching ALVR on your headset, then SteamVR or the ALVR dashboard on PC.
  • To change settings, open the dashboard on the headset with a long press of the menu button (on the left controller), change what you want and then press Restart SteamVR. The current playing game could shutdown so any unsaved progress could be lost.
  • To shutdown ALVR you need to close both the ALVR dashboard on PC and SteamVR.

Notes

  • You can access ALVR dashboard from your smartphone. On the browser you need to type the local IP of your PC followed by :8082 (for example: 192.168.0.3:8082 ).

Troubleshooting

  • To reset ALVR, delete the file session.json from the installation folder.
  • Please check the Troubleshooting page. The original repository wiki can also help.
  • You can find some setup advice here.

Uninstall

Launch ALVR.exe, go to Installation tab, press Remove next to the current ALVR installation path, then Remove firewall rules. Close ALVR window and delete the ALVR folder.

If you have a version prior to v12.0 you need to launch remove_firewall_rules.bat and driver_uninstall.bat in the installation folder.
