Exactly the same problem here so I contacted support@flightsimulator.zendesk.com… hope they can help me. If they come with a solution, I will inform you here.
My configuration is:
motherboard: AORUS x570 elite
Chipset: AMD Ryzen 9 3900X 12-core
Video card: Nvidia Geforce RTX 2080 Super 8 GB
Windows installed on: Samsung SDD 980 PRO partition 1
MSFS2020 installed on: Samsung SDD 980 PRO partition 2.
The situation is as follows:
If I switch to VR mode in MSFS2020 I experience no problem in the menu of MSFS2020.the moment I actually start flying, I see (in the VR glasses) the cockpit in VR for a short moment, then the image immediately switches back to the image of the villa of WMR. Then the image (and sound) gets into a loop of the “exploding ball” and I return to the villa every time. On monitorscreen, however, I do see a VR image of the cockpit, but I do not see this in the glasses and I keep hearing the sound of the starting VR mode.
The weird thing is that it worked in the past, but suddenly it doesn’t work anymore. I even completely reinstalled both Windows 10 and MSFS2020 (clean install) but this did not work either, so I turn to you for advice. I hope you can help me.
