This behaviour is not consistent. Sometimes it crashes, sometimes it loads. So, I went in and out of VR at the Main Menu a few times until I received this memory error.
Do you have the same issue if you follow the OP’s steps to reproduce it?
yes, exactly the same issue. Using windows 11, Ryzen 9 9500 CPU, Nvidia 3080 GPU
Provide extra information to complete the original description of the issue:
Turned on DLSS and DX12, VR worked twice but then after I restarted MSFS again and tried to enter VR from main menu, I experienced a CTD. I turned DX12 off and tried again and it worked fine. I I tried turning DX12 back on again twice but with the same effect.
If relevant, provide additional screenshots/video:

For me, for the two times VR worked when using DX12 it appeared to make a big difference. Unfortunately, after two attemps, MSFS will not enter VR when DX12 is turned on, it just crashed to desktop everytime. If i turn DX12 it’s fine. No issues at all with DLSS, although I see almost no improvement (maybe 1-2 fps). Hopefully DX12 can get sorted and maybe tweaked a little when SU10 is fully released as for me it appears to make a big difference in VR (when it worked).
I beleive I have discovered the problem. I was using OpenXR Toolkit when I had DX12 enabled but the OpenXR Toolkit isn’t yet compatible with DX12. When I turned it off, it worked fine with DX12.
I had 3 CTD crashes without any message, during a session test with VR and DirectX 12 beta
(3 tries, 3 CTDs)
I don’t have Open XR Toolkit installed.
When I went back to Directx11 everything went well in VR

I get a CTD when I activate VR in SU10 with DX12 and DLSS enabled as well. I do not have the OpenXR Toolkit mod installed. I just freezes soon as I try to activate it and then closes MSFS after a few seconds. Tried taking DLSS off and same issue. Going back to DX11 now and see if it works for me there.
yeh same here, its not consistent tho one time itll crash next it wont.
xropen toolkit turned off with DX12 so its not that, it behaves slighty better if FS is at main menu point before activating VR but does still do it now an then but if you try going to VR when games loading it crashes just about every time which it didnt do before SU10 beta.
it doesnt even give an error message either which is wierd.

Thanks folks for the reports. I’m hearing at least a few users reporting this specifically on WMR, and we (OpenXR for WMR team) are actively looking into it. Thanks for your patience.
I have found if i go into an airport before I switch to VR when I am running DX12 helps me. Once I am loaded into the sim I can go back out to the menu and everything is fine untill the Graphics glitches happen. But I have had some nice flights with DX12 and DLSS when I can get it to work.

I’m on Radeon Pro W6800X 32GB graphics card (the Apple version) on a Mac Pro 2019 workstation, so no overclocking or anything like that, also with Reverb G2. I have it connected to the Thunderbolt Port on the W6800X (via Microsoft Surface USB-C adaptor) and a USB-C port.
But I was also having non-stop CTDs any time I was switching out of or into VR mode. DX11 or DX12 didn’t seem to make a difference. I checked and nothing was overheating (which it shouldn’t anyway).
What I did was uninstall OpenXR toolkit and reset the Windows Mixed Reality Portal as well. Two flights completed today after this with no crashes and multiple times switching between 2D and VR modes.
Tonight the flight was in DX12 mode, no problems encountered. Maybe this might give you some ideas to try.
