Gierasimov Posted April 27, 2021 Share Posted April 27, 2021 (edited) 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 Edited May 6, 2021 by Gierasimov Status update 1 1 Intel i7-13700KF :: ROG STRIX Z790-A GAMING WIFI D4 :: Corsair Vengeance LPX 64GB :: MSI RTX 4080 Gaming X Trio :: VKB Gunfighter MK.III MCG Ultimate :: VPC MongoosT-50 CM3 :: non-VR :: single player :: open beta Link to comment Share on other sites More sharing options...

silverdevil Posted April 28, 2021 Share Posted April 28, 2021 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" 1 AKA_SilverDevil AKA Forums My YouTube “It is better to keep your mouth closed and let people think you are a fool than to open it and remove all doubt.” — Mark Twain Link to comment Share on other sites More sharing options...

XPACT Posted April 28, 2021 Share Posted April 28, 2021 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. Link to comment Share on other sites More sharing options...

silverdevil Posted April 29, 2021 Share Posted April 29, 2021 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.
