dcs.20231021-175426.logdcs.20231021-175426.dmpdcs.20231021-175426.crashAfter the update to 2.9 i can´t use my VR-Goggle anymore. When I open DCS after a short period of loading,  the game crashes back to desktop.

When I delete the options.lua file in the dcs savegamefolder the game load in 2D into the main menü, when i go to the VR Optionsmenue and activate the Enable Virtual Reality Headset, the game reload and chrashes again.

I use SteamVR beta 2.0.6, Valve Index, Nvidia Game Ready Driver 545.84, Zotac RTX 3080, Win 11,

I have an 2.5.6.Version of DCS World on my PC and there it works fine.

3. post your issue in the appropriate forum section with your dcs log

 

C:\Users\yourname\Saved Games\DCS\Logs

 

Thank you

 

Just zip the entire logs folder upload here.

It could be another "out of memory" issue, You can try increase your pagefile size to 32GB

but we need your logs and crash file to be sure.

Did you try repair and verify the game?

Some of the mod's scripts were broken. textures is also unable to load. weapon date is all wrong

you said you have a 2.5.6 version; it seems something is mixed up? 

We need you temporarily remove all the mods and settings:

1.Cleanup and repair the game

2.Rename the "DCS" folder as "DCS_BAK" in C:\Users\yourname\Saved Games\

then restart the game

 

the crash relates to Visualizer.dll HMD render error. But so many other thing goes wrong in the log. We may need @Flappie to trace the dmp.

Hello, thank you for your help. I have now deinstall dcs 2.9 beta and deleted also the savegamefolder of dcs 2.9 beta. There are now no mods installed.

But the outcome is the same. After the fresh installation dcs load into the menue, and when i activate the VR Device the game crash. 

In the new crashlog there also many errors and warnings. I have cleaned my ssd from dcs files and downloaded dcs from the eagle dynamics side. Maybe its something with the nvidia driver. I will check out, but as i wrote the DCS World 2.5.6. works fine.

Do you have your VR device on and ready to go when you choose VR mode in DCS?    If my goggles are not on and I load up DCS my game will crash....  So I always have my goggles on before I load into DCS..

[Schwede150]

Yes, SteamVR and the Index are on, before i start DCS. 

I had no problems with the 2.8 version, after the update vr crashes.

[Insonia]

In that cases, most of us unable to track the dmp file, so only ED can investigate this issue.

We dont know how long they will notice your problems

If you are in urgent, you can contact dev team directly and upload your dump and logs to,

Thank you for your help, i have installed now dcs world 2.8... and it works fine. Maybe i try 2.9 later again.

This Topic can be closed, thank you.

DCS 2.9 MT was crashing every time right after loading the 15 year logo. I found that disabling Quad-View resolve the issue and I'm able to run in VR again. The production version 2.8 have no problem with my Quad-view.

FWIW I have been experiencing random crashes on startup with the MT version since one of the later 2.8 updates around the end of July. I am on a G2, but my Aero is en route right now.  I seem to have better luck starting WMR first, and then the game with the forceVR flag. Some days it works every time, other days I turn on the system and it's several crashes in a row. Whatever it is, I don't think it's headset-specific.
