Did you make sure that motion reprojection in OXRTK is disabled too because your frame rate is very close to 30 FPS which is what motion reprojection could be targeting? Make sure it is set to default and also go into and out VR a couple of times because sometimes the change doesn’t stick until the second go.

Yes it is set to default.

Also, check with Windows task manager performance view that your CPU is running at the correct speed. Here’s what mine looks like while in a VR flight in MSFS and you can see that my CPU is running at over 4GHz. If yours isn’t, check whether there is a newer BIOS for your motherboard that you should install.

It usually runs at 4.45 GHz (PBO undervolting in bios to -25) at around 60-65°C

If you want I can load up a flight somewhere more complex of your choosing in the FBW (I don’t have the Fenix sorry) or the A310 (which is heavy on CPU like the Fenix is) and see what I get. I can also try your exact settings if you want, which you would obviously have to let me know. For reference, my settings, which are the same as I was using with my 4080 except custom render scale was 150%, are:

That might acutally help a lot to see how the CPU behaves… I have read a few times, that the Fenix is heavy on CPU and that could add to the MainThread limitation.
My test scenario is LSZH (with FSDT Scenery, but the Gaya Scenery that came with a World Update will also do the job) and broken clouds.
