Greetings,

My quest2 can't launch openxr in MT&ST, my DCS is OB 2.8.8.43704(in release version 2.87.42718, it can't launch openxr in MT&ST either) .

When i use"  --force_enable_VR  --force_OpenXR" with dcs MT shortcut command line. The log said:

2023-08-24 14:24:19.374 ERROR   VISUALIZER (Main): OpenXR exception: runtime is not available 
    Source: Projects\Visualizer\Source\OpenXR\openxr_program.cpp:322

 

But if I use"  --force_enable_VR  --force_oculus_VR" with MT,dcs can launch in Oculus VR runtime correctly, the log said:
2023-08-24 14:30:47.589 INFO    VISUALIZER (Main): LAUNCH IN VR OculusRift: OculusRift: Oculus Rift S

I also tried" --force_enable_VR--force_steam_VR" with ST, dcs can launch inOpen VR correctly, the log said:
2023-08-26 02:31:53.535 INFO    VISUALIZER (Main): LAUNCH IN VR OpenVR: OpenVR :

I also tried in DCS steam verion,it has the same issue.
I tried WARTHUNDER,which natively supports openxr, and it can launch in openxr correctly.
I think there is something wrong with my openxr setup. Hope you guys have some recommendations, I am out of ideas.

 

My Oculus App Version is 56.0.0.109.155,and already set openxr as active runtime.
Openxr tookit v1.3.2 is active.
Opencomposite set to openxr.

Thanks！
