VR in MSFS2024

Its a mixed bag… Some things broken entirely such as no ability to complete career mode in VR. I have had better and worse performance and visuals and just trying to work out cause so I can get a better experience. Last night I got things running well with everything medium settings in dev mode with about 52fps switched on half refresh in pimax so locked to 45fps and everything was smooth for about 30 mins then just fps crash to 30fps and could not get higher again even reducing to minimal settings and low res??? It doesnt make sense something weird is going on with it. someone elses opinion on performance. https://youtu.be/YeN3UPfjXXY?si=MWYsHve_dnxRa8hk
