I had this all setup and working for a few months now. I missed a few weeks flying and now after the usual intervening update when I run things up I get a 10FPS with higher theoretical. I am setup to use the Varjo Open XR but it does not seem to be working and I am not sure why. I can set SteamVR as the OpenXR runtime and it works but capped at 45FPS. Not sure what has changed that Varjo OpenXR doesn't seem to work anymore I have tried changing all permutations of the DCS command line settings but I normally run it with "-force_enable_VR --force_OpenXR". I don't have the OpenXR toolkit installed but did previously. I uninstalled it as part of ditching my Quest 2 for the Varjo Aero. Has anyone else experienced this? Any advice appreciated.

Same problem in Mission 8 Cheers, Headroom
