DCS lockup/Crash “black screen” in VR.

[NBee]

I have problems with DCS generate black screen in VR headset and freezes game in WMR.

 

Using HP G2, Windows Mixed Reality + OpenXR + OpenXR Toolkit and DCS native settings

"F:\DCS World OpenBeta\bin\DCS.exe" --force_enable_VR --force_OpenXR

 

System spec:

Lates DCS-beta, Win 11, AMD Ryzen 7 5800X3D, Nvidia RTX4090, 32 Gb RAM

 

See attached 3 x log files.

Crasch 1 dcs.log Crasch 2 dcs.log Crasch 3 dcs.log

Did you change the launch method? I had a similar issue after trying to use SteamVR, the shortcut with the - -force_OpenXR argument caused a crash. SteamVR had messed up the dll-s. I managed to clean that up but not quite to get a good performance. Same headset, 5800x (no 3d) and ram but AMD GPU.

First I located the problem for the blackout/crash.

It seems like DCS don’t like Turbo mode on in OpenXR Toolkit ver. 1.2.3 when its on DCS locks after some time in VR.

Launch method: I use DCS native support for OpenXR no Steam or OpenComposite app installed.

Did you resolved the problem? I have similar experience. Game freezes and turns black screen for some seconds once in a while usually while in busy places. In multiplayer it often and crashing to the ground. Very annoying.

As I wrote earlier, this problem was the result of turbo mode in an old version of OpenXR Toolkit ver. 1.2.3.

But I also had the problem afterwards as a result of a headset that was defective, The headset freezes for 1-2 seconds, then it wakes up again for about 10 seconds, after which it freezes again for 1 second, after which it works without problems.

I had the headset replaced under warranty via Hp. which solved the problem temporarily but unfortunately the "new" headset has developed a "black screen" problem and won't boot so I don't think this problem is DCS related but a result of of, two a row faulty, headsets from HP.

So I have decided to replace my headset with a Varjo Aero instead.

Always; always do any troubleshooting at all without any third party software running.

Unbelievable, the same day Don posted this he posted a farewell in Chit-chat, falling victim to cancer, and he was gone ~10 days later.  Great guy, always there with advice and help, he will be missed..

Devastating info about paasing away...

 

My VR black out solution was fixed by my RAM settings in BIOS. My computer was using only half of my RAM becuase of my faulty settings in BIOS.
