Build Crash : DirectX 11 & Unity 5.6
After a whole day trying to understand why my build randomly crash during loadings (any loading) after upgrading to Unity 5.2, I finally found something quite odd.
We tested builds on several configurations :
Windows 10 with Nvidia GPU : crash
WIndows 8 with Nvidia GPU : crash
WIndows 7 with AMD GPU : OK
Windows 8 with AMD : OK
Seems Nvidia related...
Log files have more or less validated this hypothesis :
The crash log :
**nvwgf2umx.dll caused an Access Violation (0xc0000005)**

**** Crash! ****
To have a build running fine once again, here is what I did :
Updating Nvidia Drivers : Still Crashing
upgrading to Unity 5.6 : Still crashing
Enabling x86_64 bits : Still crashing
Enabling / Disabling GPU Skinning, Graphics Job : Still Crashing
Removing some dlls, removing some plugins : Still crashing - Disabling DirectX 11 : no more crashes...
So I found my problem, but the solution is quite odd, and is not really a solution. Cause I'm not really sure that disabling DX11 is a really good idea..
Does anyone have a proper solution or know why do I have this issue ?
Thx by advance.

Can you take a look at my post and see if yours is similar? There are posts all over the web about NVidia's nvwgf2umx.dll crashing games. I'll try disabling DX11 for our projects...
thanks
The link you"ve posted yesterday doesn't seem to be the one you wanted to :)

Sorry - the forums had a security breach and my post was nuked in the restore. I created a new one...

PS: If you have your error.dmp from your crash, load it up in Visual Studio, set the symbol path to something like this and hit play to get a better stack...
$$anonymous$$icrosoft Symbol Servers C:\Program Files\Unity\Editor\ C:\Program Files\Unity\Editor\Data\PlaybackEngines\windowsstandalonesupport\Variations\win64_nondevelopment_mono\ C:\Program Files\Unity\Editor\Data\PlaybackEngines\windowsstandalonesupport\Variations\win64_development_mono C:\Program Files\Unity\$$anonymous$$onoDevelop\bin\ [and path to your .exe/.pdb]
thanks

Some of our users are reporting the same crash with the dll causing an access violation.
What did you mean with "Disable DirectX11" ? Did you mean to say DirectX12?
@Paul_Bronowski did you find a fix?
