DCS crashes to desktop on startup when using VR.


Recommended Posts

Hi All,

Starting a few days back, When I start DCS MT using the following parameter "--force_OpenXR —force_enable_VR" as I always have, it starts and when it gets to the black screen, it then crashes to desktop. It also does it with STEAMVR as well. Starting DCS in nonVR is fine. I don't believe I installed or changed anything that would triggered this issue when it first started. All other VR software that uses OPENXR or not works fine. i.e. IL2

Since the is problem has started  I have uninstalled-reinstalled Pimax software, PimaxXR, OpenXR toolkit, Quad-views-Foveated utility and Nvidia Drivers. I ran safe mode in OpenXR toolkit with no change.

Finally, I reinstalled DCS  (separate folder), same thing. I have attached the DCS.log

Doe anyone have suggestions to what next to try. Any help would be appreciated.

System: AMD 5900X, 32GB RAM, RTX4080.

Thanks in Advance.

I see that you using PimaxXR v0.4.4

Perhap try different earlier version of PimaxXR.

I remember sometimes I do get black screen on my Pimax 8kx.. going back to earlier version .. from memoy v0.2.x .. always worked.

DCS now supports OpenXR natively, see 

Also, why do you have Windows Mixed Reality selected in PimaxXR? Give it a try without the force option and the WMR.

Only for the controller which is not used in dcs. I had it before and it worked as a setting and I have tried it blank with no success.

tried removing force on the openxr and still no go

Just tried 0.4.2. Still the same.

0.2.8 is still the same.

please double check your shortcut 

OK that worked.

I did have --force_OpenXR —force_enable_VR

and I used your suggestion 

--force_enable_VR --force_OpenXR

which worked. I am sure I swapped these around to see if it would fix the issue.

Anyways.. problem solved. Many thanks.

I think it is because you are using a minus here and not --

Yes.. Most probably. It would be useful if ED gave us a launcher with options like this as tick boxes. Included also to do integrity checks etc.

 

Just an idea.
