September 29, 20214 yr Author 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).
September 30, 20214 yr 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: https://www.avsim.com/forums/topic/606945-nvidia-47196-and-dxgi_device_hung-resolved/?do=findComment&comment=4634657 NB: I didn't change TdrLevel on my test system, but I had to change TdrDelay to solve another peculiar bug: PSA: Solution to HDD and NVidia causing Win10 System Halt with Black Screen - Virtual Reality (VR) / Hardware & Performance - Microsoft Flight Simulator Forums Edited September 30, 20214 yr by RXP
