As many of us, I was getting a lot of crashes in 2.7 beta and submitted numerous crash dumps to the automated process. 

Investigating the error log I noticed that ALL my crashes, while at different times, situations, aircraft, all shared the common message logged in the dump:

 

EDCORE: C:\Windows\SYSTEM32\d3d11.dll (this .dll would then be one of the listed below).
EDCORE: # C0000005 ACCESS_VIOLATION at 6E7F6BAE 00:00000000

 

I also noticed the Event ID 1000 pointing to these things:

 

Top occurrence would be:

Faulting application path: E:\DCS World OpenBeta\bin\DCS.exe
Faulting module path: C:\Windows\SYSTEM32\d3d11.dll 

 

Then less frequent:

 

Faulting application path: E:\DCS World OpenBeta\bin\DCS.exe
Faulting module path: C:\Windows\SYSTEM32\ntdll.dll

 

Couple of:

 

Faulting application path: E:\DCS World OpenBeta\bin\DCS.exe
Faulting module path: E:\DCS World OpenBeta\bin\Transport.dll

 

One:

 

Faulting application path: E:\DCS World OpenBeta\bin\DCS.exe
Faulting module path: E:\DCS World OpenBeta\bin\dx11backend.dll

 

Now, I prefer working DCS, so I decided to disable Windows DEP, just to check if that would help me.

 

It did. 

 

Now, as an systems person, I would not recommend disabling Windows DEP, however, since DCS is a 64-bit application and Windows DEP protects all 64 bit files by default, the only option is to disable it, one cannot make an exception for DCS only. 

 

It helped me a lot. No crashes anymore. If you want to try:

 

Open Command Prompt as administrator, then type:

bcdedit.exe /set {current} nx AlwaysOff

Reboot and test,

If you are not happy with it, you can enable it with bcdedit.exe /set {current} nx AlwaysOff command.

 

Do it if you want, don't do it if you don't want. Sharing it here as my DCS runs flawlessly now and I was struggling to run a stable 1 - hour single player mission before.

----------------------------------------------------------------------------------------------------------------------------------------------------------

 

30.04.21 - I re-enabled my DEP now, and testing the new drivers from nVidia -466.27

 

So far I had no crashes in typical scenarios, but testing in progress. 

 

06.06.21 -- good, stable beta

I would like to suggest turning DEP for just DCS. https://www.online-tech-tips.com/windows-xp/disable-turn-off-dep-windows/ look for section "How To Configure Or Turn Off DEP"

Even 64bit can be excluded, but its then an extra work to exclude all of needed applications then.

Risky!

I know. But makes my DCS run without issues. 

I always fight with SecOps teams at my workplace trying to balance security with usability...

I will just say this:

 

when you turn DEP off and it really helps with the issue that means that executing program is not using system memory in a safe manner, all kinds of issues can occur if left like that

 

Not to mention all possible exploits and security risks involved with disabling it. I wouldn't do it except for debugging purposes.

@icemaker - you probably should start your own topic. but your issue appears to me to be the following:

did a quick search for this file name and found lots of crashes for other games. this is a video driver issue.

I had those errors in my logs too, when DCS suddenly started crashing. For me it has helped to roll back Windows Update KB4589212, which was installed on my rig earlier this week:

Interesting. Further research found that this particular update was released in 2020. It was reissued. It was for Intel Microcode for some vulnerability. It appears to be a forced update. But the file itself is from NVIDIA.
