Star Citizen never was supported, and probably never will be. The desktop viewer workaround in the video above however should work, it’s not officially supported though.
Anyone have success getting this working for an HTC Vive? I followed the instructions word for word. When badboy says the Oculus software should launch, my SteamVR launches, but it just takes me to my VR “home” and the game continues to run on my monitor only.
