Many thanks to everyone for their comments and advice. I’ve ended up spending a lot more time, several days, working through the various tuning options that have been suggested. For consistence during testing I employed the TBM 930, including the Working Title G3000 V3.4 upgrade, and my local airport (EGHH).
At the end of the first day, having tried many of the recommended settings, I almost gave up; performance was poor, and the simulator became very unstable; with very frequent CTD.
As I was clearly getting nowhere, the following morning I went back to what might be considered first principles. I uninstalled OpenXR Dev Tools and loaded the Nvidia 457.30 driver and set everything to default. I chose 457.30 as it had previously worked well with my 3090. I also employed Process Lasso Pro to allocate 2 CPU cores exclusively to WMR and the remaining 30 cores to FS2020 and general housekeeping.
Fortunately, these changes resulted in an immediate improvement in both performance and stability. I was then able to gradually adjust the in-game settings to achieve a good smooth judder free experience in VR For reference, the fps is now running consistently between 32 & 38 fps in all the locations around the world that I’ve tested so far. Please refer to the list below. I’ve also noticed a slight overall improvement by using the same in-game settings for both the PC monitor and VR headset.

My in-game settings are as follows, I have settled on 100% render scaling and have avoided motion reprojection as this setting provides by far the best image quality.
I still have a performance problem with the Flyby wire A320NX, a firm favourite of mine, but which I believe is hampered of poor processor optimisation. The main thread appears to be disproportionately loaded which is bottlenecking the rest of the system.
