You can only turn on dfr through openxr toolkit. The settings in pimax play (latest version with openxr integrated) do nothing, unless the software supports quad-views (which MSFS doesn’t). You can see that in pimax play, it will always say “ dfr off” in the bottom left corner of the settings screen, no matter what you select in pimax play.
Okay thanx, that I didn’t know
Turned on HAGS and, again just to try something, turned on latency mode in Nividia Control panel for FS2020 to Ultra.
Updated FS2020
Cleared DXcache and GLcache :
50FPS at 18/19 m/s , average was 48 fps at 21 m/s
This is with the Pimax Crystal resolution on 0.90 and rendering scale in FS2020 90 %.
It only took a stage dive when I got over Los Angeles ,which isn’t weird, this is, beside New York, the most hardware intensive city I have with payware and freeware add-ons, 32 fps at 27m/s
(Flying at 1500 feet with the Azurpoly OV-10 Bronco Cal Fire)
It hasn’t bin preforming this good for weeks : I ain’t touching NOTHING anymore.

That is excellent.
I do wonder what DLSS in quality mode might do for you. I just find it looks and performs better than TAA if you have to drop your render scaling. TAA looks better at 100+.
I do find it hilarious how fast machines need as much configuration as slow ones in this sim.
Is it your CPU or GPU that causes latency in LA? That might be a CPU thing.
And by all means ignore me if you are as happy with your performance as you sounded above.
What I’m seeing is that the CPU only wakes up when your near or over a big city ( going to 15 to 18+ m/s).
It’s the GPU that’s doing all the work, the only way to get it below 17 m/s is to run FS2020 without the scenery addons.
I’ve tried DLSS once, when it got supported, and switch back to TAA immidiatly : graphics, view everything look horrible.
I’m still hoping Asorbo release a update that implements decent multi core support and makes better use of availble RAM.
Currently it’s like your trying to push 300 bar’s of fluid pressure true a garden hose.
Like I said, it is all about balance between that CPU under high load and your GPU. Trying to get the latency similar betweetge two gives you the best fidelity on your system.
Configuring for 2D is a bit easier and might help you find your way around VR.
I have configured MSFS for so many systems now. 5 or so. You really can keep tweaking things and getting better and better results on a medium system or better.
But it does look like your VR slows your GPU down when run at super high resolutions.
If you use DLSS, there are other ways to sharpen from there.
But yeah, I totally get it. I tend to configure for medium cities not the big ones. It just looks so much better everywhere else in the world other than Tokyo, LA, or NYC.
But on your system, I would want that NYC smooth performance! 
DLSS has had several updates since Asobo introduced it. Not sure if they have included them in the Sim Updates, but you can do it manually. There are some threads on this forum on how to do it.
For me using TAA is a total frame killer. With a 5800x3D and a 4090 I use DLSS Quality and override the resolution above 100% plus sharpening in the Toolkit (can’t remember the exact resolution numbers). I also lock framerate at 45fps (i.e. half). I don’t use dynamic foveated rendering, as it gives me artifacts in the clouds. I can maintain 45fps in most scenarios at around 1,500 feet in GA aircraft and even over most photogrammetry cities like Rome. Things look very sharp, though not as amazingly crisp as they did when we had the Almalence digital lens plug in (I was extremely upset that Pimax opted not to adopt it).
Edit, I currently use DX11, Win 10, clouds High and shadows on Medium, ambient occlusion off, reflections medium.
