Hey guys,

I am trying to get DCS running while with my Quest 3. After watching a handful of videos, it seems that using OpenXR is the best way to run VR, especially the Quest 3. After initial setup, I was able to get the game setup and running well with OpenXR, however, the game now crashes everytime I try to launch with OpenXR.

I am using the MT launcher with the following in the Target: 

--force_enable_VR --force_OpenXR

I will post the files from my most recent crash.

One interesting note, it doesn't always crash if I launch DCS thru the oculus software. However, I then don't have access to the OpenXR tools in game.

Also, I did find some threads discussing crashes on startup in VR, and they solved it by changing the Paging File Size. I did try that, did not work for me.

Thanks!

The crash is caused by a function called "try_get_HMDcontroller_pos". It's like DCS is not able to determine your HMD device(s) position or status and crashes as a result.

Thank you for the suggestion. I seem to be getting the same error.

I do think I am going to complete a fresh install of DCS and see if that helps. Do you have any other suggestions?

Wait, have you at least tried the solution in the linked post?

Hey Flappie,

Haha, I did! Sorry if that wasn't clear in my last message, I sent that a little late last night a may not have been fully awake!

I have DCS reinstalling right now and will try it out soon. For now, here is the list of things I have tried to do:

  • Ran a DCS repair
  • Deleted MissionEditor and bin-mt folders and then ran the repair
    • I found these suggestions somewhere on the forum
  • Launched DCS without OpenXR
    • This worked the first time, but hasn't since
  • Ran OpenXR in safe mode
    • This actually got me in the game briefly!
    • Allowed me to reset my OpenXR settings, assuring that Turbo Mode is not activated
  • Tried changing my Paging File Size
  • Deleted the regedit key as suggested by Flappie

Symptoms I am having:

  • More times than not, the game does not launch and just crashes to desktop
  • If launching with OpenXR, sometimes the game will launch and appear like it is working. Then, I pickup my headset, and the second the headset recognizes that I am putting it on, the game will crash. This then leaves me in a black 3D space with the OpenXR menu floating in the corner of my eye. I can move my head around at this point, but can't navigate the menu.
  • If launching thru Oculus app, similar to what happens with OpenXR, but in my headset I just see an hour glass in the bottom right

DCS launches just fine in 2D. When I performed my initial setup with OpenXR, DCS launched, and I got it running quite well. I was able to relaunched the game multiple times, dialing in my settings. I then was able to fly a brief SP mission in the F-5. For no perceivable reason, the game started crashing on launch during this process. Maybe I enabled Turbo mode?

Another thought, the SSD that I have DCS installed only has about 20 gb left on it (nothing else on this drive). Could having a nearly full drive cause issues like this?

There's something strange in your last log: 

2023-12-03 16:46:19.367 INFO    APP (Main): Command line: "D:\DCS World OpenBeta\bin-mt\DCS.exe" "D:\DCS World OpenBeta\bin-mt/DCS.exe"

And even in the former log: 

2023-12-01 00:43:35.066 INFO    APP (Main): Command line: "D:\DCS World OpenBeta\bin-mt\DCS.exe"

You said you were using --force_enable_VR and --force_OpenXR but they are absent from your log files.

Can you show us how you use these two parameters to start DCS?

Hey Flappie,

Sure, I have them in the "Target:" field in my shortcut to the exe. Check the logs I have attached here, you can see that it is operating correctly. Since I have been getting the same crash reason for every method (OpenXR, Oculus, SteamVR), I was a little careless with which logs I posted.

In my most recent test, I did get DCS to launch using SteamVR. However, it did not run correctly at all. I loaded into the Apache and I while I could see the cockpit and my head moving around in the VR preview on my desktop, my headset was just stuck with the hour glasses spinning, occasionally flashing frames from in the game.
