Rift (or Quest) with P3D 5.3 DEVICE_HUNG on exit

Hello, 

I recently set up a new rig (11900k, Gigabyte RTX 3080, 32MG DRAM)  and installed Prepar3d 5.3 and my Oculus Rift VR.   Every time I disable (exit) VR (from within P3D menu) it crashes with DXGI_DEVICE_HUNG.  Every single time.  I'm not overclocked, no Enh Atmos, No HDR.  Still crashes.  

I also tried it with the Quest 2 headset via Link cable (which works fine otherwise), same result.  Crash when exiting VR.  I am monitoring the state of the GPU (a not cheap RTX 3080 card) with task manager performance tab, and I see a huge spike in GPU usage when the exit VR command is given.  

this is always with a PMDG bird of some type, so far either 737NGXu or a 777.  thats really all I fly in P3D.  Any suggestions ?  I'm lowering settings but this feels ridiculous with this much compute power.
