Yep. Pop on WMR headset. See Cliff House (I changed my to the Loft, as they used a picture of the Vancouver mountains as the world sphere, so I liked that) and then either press the Windows button on your controller or if you don’t have those around then just press the keyboard Win key and the blue ‘shortcuts’ window appears. Use the mouse to find the ‘Desktop’ entry and click that. You now have a big desktop widget in your house. Use the mouse to click into it (drag it closer, resize it if you like) and now find your desktop DCS icon you’d usually use on the Desktop within this VR widget view. Double click it to start DCS.
SteamVR will start up, you’ll see rushing white dots, and now everything should be ok. You might need to reset your WMR settings if you’ve turned anything off. You can press the hamburger (three lines) on a controller to do that, and find WMR in the SteamVR dash.
I guess having WMR initialized properly before DCS starts up via SteamVR is the key thing to stop reprojection from crashing perhaps?
