VR Freezes immediately on launch of DCS

[brodie4598]

Since the last update, When I start DCS MT, the VR only works about 20% of the time. What happens is the displays in the headset are black and the preview screen is frozen in whatever position the headset was when the game initialized. Only thing I can do is kill the process and restart over and over - it usually takes about 3-5 tries to get it to run correctly. 

I have a reverb G2.

No errors in DCS.log

Same. Reverb G2. Can see game on the monitor, but headset is black. Running MT beta. I did a clean and repair. No help.

Have you tried using SteamVR as the OpenXR runtime?

Once - and it worked. But SteamVR performance is garbage for me so I didn't test it a lot.

Personally I find OpenXR using the SteamVR runtime rather than the Microsoft one smoother. Not to be confused with SteamVR OpenVR which DCS use to use just for the avoidance of doubt.

Had that Problem yesterday with the F-14. Start of the Mission, press the Fly Button and that's it. Dark Screen with bouncing Balls. The Mirror stuck with a dark lower Half. Had to kill the Thread. Next Try and a little longer Wait before the Fly Button Press all was well. Shortly before that i had a Slow Repair and deleted the FXO and Methashader Folders. The Textures are also a little slow loading.

Reverb G2. OpenXR.

I think I was able to figure out the issue although I am not sure if this is a problem in DCS or not. However, it doesn't happen with any other games and it did start after a DCS update.

I have found that the issue is I am not putting the VR headset on my head before starting the game. In the past, my usual process was to start DCS but not put the headset on because it takes a good few minutes for DCS to start up. 

To get around this, after starting WMR I put the headset on to wake it up, then I set it back on my desk and start DCS. I have not had the issue recur since.

I've had this problem repeatedly, along with a really long load time (3+ mins).  When i kill the task and restart DCS, it loads in <30 seconds and loads the headset correctly.  Seems to be an initial load issue/compatibility issue.   Nothing odd shows in the log.

G2, OpenXR (updated), 10600k/3080/64Gb ram.

I get the same problem (multiple aircraft) ,runs for a short while then the VR hangs. It will runs for hours in MSFS on same VD settings.
