Hi Guys

So I tried no less than four times to fly with the FSLabs A320 in P3D V3.4 today, and every time after about 15-20 minutes I would get a CTD with the faulting module nvwgf2um.dll.

I know this is something Nvidia related. I've tried two sets of drivers, the brand new ones (382.33) and the old faithful ones that used to work well with my GTX 970 (376.33). I uninstalled with DDU and Ccleaner etc. I can't get rid of this error. This is on a completely fresh install of Windows 10 and P3D too. I've got no tweaks in the CFG file at all. Graphics card is not overclocked.

Specs if they help:

i5 3570k at 4.7GHz

16GB RAM

2 x SSD's

GTX 970

I've done pretty much everything in the Avsim CTD guide. SFC scanner shows 100% integrity, all drivers are up to date, scanned all the disks with no errors, run memtest x86 and memory is clean, stress tested the overclock for 10 hours with no errors or temperature issues. DLL and EXE startup files are as they should be. I'm completely out of ideas and it's driving me up the wall.

Crash with 376.33 drivers:

I'm all ears if anyone has any words of wisdom.

This error is most likely caused by a high overclock, cpu voltages too high or too low.  If your system is overclocked, try to go to the optimal defaults or the default setting for the BIOS.

If you are trying to overclock your GPU, remove the overclock.  GPU's should only be overclocked by the developer of the GPU or by a computer professional.

If none of the above applies, I would rename or delete your p3d.cfg and let it rebuild.  It is possible a setting is too high for your GPU to handle properly.

Best regards,

Thanks. I've found that it ONLY occurs with the FsLabs Airbus. PMDG 777 and 747 are flawless for hours of flying, FsLabs will always crash with that error after about 20 minutes. Odd. 

Odd.  Yes.  If it was a cause of FSL's, everyone would be reporting the same error.  I have not seen this.  It is most likely a setting in your config that triggers the error.

Best regards,

Jim
