Brief description of the issue:

Intermittent CTD when changing graphics options. Most often a change of Terrain LOD but have also had it when switching from DX11 to 12 or vice versa. Crash seems to be occurring in one of the Nvidia dlls - nvwgf2umx_cfg.dll. Not had anything like this in any previous SU

Provide Screenshot(s)/video(s) of the issue encountered:

Do you have the same issue if you follow the OP’s steps to reproduce it?

Provide extra information to complete the original description of the issue:

Got this when attempting to remove ground traffic on taxi after landing (so during a flight) at the point where I tried to resume the sim. I wonder if I’m experiencing a more general (albeit sporadic) issue when resuming after changing options during a flight.
Faulting module nvwgf2umx_cfg.dll
Latest Nvidia drivers 516.94

This is related the Nvidia driver set. Disable any GPU overclock if you have one - that’s usually the source of crashing for Nvidia drivers.

It might be worthwhile to do a clean install of your GPU drivers, just to make sure there’s nothing corrupted.

I’m not running any overclock at the moment and I did do a DDU clean up when I reverted from 516.59 to 512.77 prior to installing the latest driver set. All 3 versions gave me this crash. This issue I’m having doesn’t seem to be widespread so it must be something in my setup. Will do another full driver clean up and see
