CTD in MSFS 2020 On Start-up. Microsoft/Nvidia Issue (DLL 190_E658703)

User Support Hub Crashes (CTDs)

ISSUE DESCRIPTION

MSFS 2020 will crash during startup just slightly beyond halfway on the status bar. To fix I must remove the DLL 190_E658703 from C:\ProgramData\NVIDIA\NGX\models. I realize there are other similar threads but your “How to Post” [sic] instructions are so convoluted and confusing I decided to post it myself.

FREQUENCY OF ISSUE

Always CTD if the referenced DLL above not removed prior to start.

REPRODUCTION STEPS

Double-click the MSFS 2020 icon. That’s it.

[PC ONLY] FAULT BUCKET ID

If you experienced a crash on PC, sharing your Fault Bucket ID would be extremely helpful. You can learn how to find that ID here: How to find your Fault Bucket ID after a crash [PC]

Do not experience fault bucket or error message but pulled it up anyways.

There currently is an issue with using DX11 with the latest Nvidia drivers.
Switching to DX12 or reverting to older drivers fixes the issue.

Thank you. That worked after two whole months of losing my mind and pulling my hair out. Only problem now (and it didn’t happen this time) is DX12 sometimes “ghosts” or “trails” when moving mouse, moving control surfaces and/or aircraft in general when viewed from outside, and sometimes the instruments (needles) themselves. I think that may happen however when Super DLSS or whatever it’s called is selected. I have always preferred TAA which make instruments clearer and more legible. TAA’s what I normally use. Thanks!

DX12 starts just fine. This is more of a question related to your answer. I have tuned/balanced my CPU/GPU for best performance with the frame rate counter (based a “2020 FSer’s” tutorial on YouTube). My setup works best with DX11 selected due to DX12 eating up the GPU headroom. As such I have to do the Windows+R and then delete the 190_E658703 thing every time before startup. Is there a way I can be notified when MS/Nvidia fix the DX11 bug or is it just a “surprise it works again!” sort of thing someday? Thanks for any insight.

Framegen causes the ghosting turn it off.
