I am using a Reverb G2 headset with a Microsoft Store copy of MSFS 2020. I have a problem where the VR display will get stuck in a dimmed mode. I can successfully have a couple of flights, in between which I will switch to the computer monitor (Ctrl-Tab) to set up the next flight. At some point, when I switch from the PC screen to the VR headset, the VR presentation is dimmed. When in on the PC screen, the presentation is a bright clear sky day. When I Ctrl-Tab switch to VR mode, the VR image is briefly bright on the PC and then dims. The appear is as if it is dusk. I don’t have a clear formula to correct the problem however getting out of MSDS and ecitting WMR generally resolves the problem.
