VR Error when Trying to Use Multithreading Exe

[utexgrad]

Good morning, one and all. I am having a devil of a time with the multithreading and VR. I can get the non-MT .exe to work just fine and it immediately goes into VR with my Varjo. But when I try to launch it with my Varjo hooked up and running, it never fully launches into VR and I get loads of "XR_ERROR_RUNTIME_FAILURE" and "XR_ERROR_CALL_ORDER_INVALID" messages in the log. 

I don't have the kneeboard item in the registry like I've seen mentioned in other posts, so that isn't the issue. I've also disabled OpenVR in the Varjo Base with no success.

Interestingly, though, when I try to use the " --force_OpenXR" flag in both the regular and MT .exe, then DCS fails to load. I have to launch the non-MT .exe file clean in order for it to use VR.

If anyone has any thoughts, I would love to hear/read them as I would really love to put the MT through its paces.

Make sure you have the appropriate files saved on your main drive https://github.com/mbucchia/Varjo-Foveated

Only use the MT executable for DCS. No need to disable Open VR in Varjo Base, but definiltey have Open XR enabled in Varjo Base. I think you just need to correct nomenclature for your DCS-MT.exe shortcut. Below is mine (installed on my D drive).

"D:\Eagle Dynamics\DCS World OpenBeta\bin-mt\DCS.exe" --force_OpenXR

I have my Varjo Foveated files installed on my regular C drive.

God bless you, sir! I am not using the open beta (yet), so I installed the OpenXR extension wrapper Mr. Bucchia so kindly provided and that fixed the issue. 

Much obliged for your quick reply and suggestions.
