Okay, I fixed my ReVive problem. It was an IUE. (Idiot User Error.) I’d read that having the Oculus service running when using a WMR/SteamVR headset could confuse DCS, so I set it to manual startup.
If you’re gonna run Oculus games, you kinda need the Oculus service… Ooops. Set it back to Automatic Startup and proceeded to load Vader Immortal II with no problems, and play a round of the Oculus version of Beat Sabre with no issues. Even checked out the cityscape scene in Oculus Dreamdeck. (Which is even scarier with such a clear view.)
