I have reviewed the link and checked the registry values.  The are the same as in your post.  I did take a simple test flight with the GTN750 and it appeared to work properly (fp, proc, terrain, ...). But, when I attempt to undock the window, the sim immediately crashes with a DXGI error?  I do have the latest NVidia dirvers (RTX 2080 Ti) and Prepar3D v5.2 HF.  This all remains a mystery--I appreciate your help--

P.S. I checked also the EventViewer (nothing unusual) and dxdiag (no problems identified).

The DXGI error is something out of our control and seems to be only related to P3D.

There has been a discussion lately with a solution which I believe is good:

NB: I didn't change TdrLevel on my test system, but I had to change TdrDelay to solve another peculiar bug:
