MT. DCS crashes with SteamVR

[Sparkam]

Hi, 

Every time when I attempt to start multithreaded DCS with steamVR (--force_enable_VR --force_steam_VR) it crashes on loading to main menu.

With OpenXR no crashes.

I usually play with reprojection and 180% SteamVR resolution (1944x2424 per eye). OpenXR is too stuttery even with hiher FPS.

I run DCS on i7 8700K, 1080TI, 32GB, SSD, Odyssey+.

 

I also checked performance without VR with my current settings:

Average CPU, GPU load on the same track (used low resolution in DCS settings 1280x768 for game window)

no MT, no VR
180 fps
CPU 33%
GPU 80%

-----

MT, no VR
180 fps
CPU 40%
GPU 60%

Checked before and after slow repair, removing metashaders2, fxo, mods, disabling antivirus. No difference.
