My personal battle with nvwgf2umx.dll its (for now) WIN

Hello everyone.
I’ve been battling for 2 weeks with the infamous subject dll problem.

I had never experienced this problem before the graphics card switch about 2 weeks ago.

Since then it has been impossible to carry out any flight, repeating CTD.
I thought of a buggy scenario, I thought about the drivers and changed them all, I removed all the OC profiles from CPU, RAM, removed g-sync, put it back, then removed the GPU BAR… endless drama.

I even thought about reinstalling the game.

Then one day I just used (again DDU) but this time using it with a windows restart in SAFE MODE.
After cleaning the drivers Windows restarted and automatically installed the Nvidia drivers of this version:

531.79

I started MSFS and a pop-up warned of possible driver incompatibility issues. I continued and scheduled a flight.
No CTDs.
Then a second.
Then a third.
For now I’m at 4 without crashing.

hope that this can help some of u.

Thanks for the info. I’ve been having crashes in the same module, and others related to NVidia for about the last two weeks as well. I always strip the bloat out of the drivers when I download them, so I’m going to test 536.67 as is. If that doesn’t work then I’ll start backward a bit and may end up where you are. I’ve been reading that others here have had more CTDs lately, so something is going on.

You pretty much did all the correct steps from a troubleshooting perspective. My inner IT support guy is proud of you!

It seems to be a bad component of a driver somewhere.

It might have to do with how the driver interacts with external screens, at least in my case. I tested a bit and tried the latest driver as I noted above and still had the problem. I noticed that it occured just after I had clicked on an ATC or VFR map window, which I tend to move to a second monitor. It never did it immediately, but after, I’d guess, about twenty interactions.

I moved the ATC window to my main screen and used LNM instead of the VFR map, and I’ve had five flights with no CTDs. So at least it’s working… for now.

BTW I did IT support way back in the day when 20 mb hard drives were more than you would ever need in a PC. :smiley: I still love tearing apart IT problems - just not in MSFS… I just wanna fly!

I kept on getting an Nvidia DLL error message after getting a CTD a couple of years ago and taking out my graphics card and disconnecting the cables then putting it back in solved the problem. Whether it was the same DLL error as yours I cannot remember.

Hello, still having this problem. Did this 100% fix all your nvwgf2umx.dll errors?

Since a couple days also having nvwgf2umx.dll after about 30 min into a flight

If you have this problem and have ReShade, uninstall it, it solved it for me

What’s the solution if you want to use reshade?

I’ve started with nvwgf2umx.dll crash recently and don’t use reshade. I have found that having reBar enabled with the frame generation mod active brings it on quite quickly say within 10 mins of starting a flight, but it still happens occasionally without this set in NVidia Inspector also. Anybody have any other clues to what might be triggering it?

Try removing all mods/add-ons one by one to see when it starts working again maybe

Thanks for the suggestion but from what I gathered, this is an NVidia issue, so I’ve cleared the driver with DDU and re-installed it, I’m now going to test whether it has any effect at all. If that fails then yes I suppose the next logical step would be removing add-ons. :wink:

Edit: Test one of a 50minute flight around the Philippines after DDU and re-install and NO CRASH, I even gained 10fps, so something must have gone wonky on my end with the installed driver (546.33) while I was testing different graphics settings the other day. So far so good.

Edit 2: the second test was a bust, I’m still getting crashes, totally at random with the same faulting module.

I don’t know, I have made a post in the Reshade forums to inform the devs, if you have an NVidia GPU you could maybe try NVIDIA Freestyle

You are or are not on ReShade?

I’m not using reshade

Actually i’m suffering the same crash to desktop caused by nvwgf2umx.dll

It’s quiet frustrating because i’m having these crashes with a completely new PC built with:

i9-14900K
MSI RTX 4080 Gaming Trio X
32 GB RAM Corsair Vengeance
3 SSD 4th generation 2TB

Actually i’m running 546.33 Nvidia Driver and crash occured with various different MSFS settings (both TLAA or DLSS, both frame gen or frame gen off)…

So please …do you remember which MSFS settings you was running before rolling back to default Windows Nvidia driver ??
And actually, after rolling back to oldest driver, are you running the same MSFS settings you use when you had the crashes ??

Thank you so much

Best regards

Enrico

i’m again on 531.79 and no more crash for me.
4090

Could you please share with me your MSFS video settings and your nvidia control panel settings?

Best
