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 :

========== END OF STACKTRACE ===========
**** 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.
