Crashing on Startup *Access Violation*

[SwollenPickle42-]

Hello everyone,

DCS is non stop crashing on me. Sometimes one thing works, then it crashes again after getting it going. then the fix won't work. Search for hours on forums and you tube videos and sometimes find another solution that works once or twice. One of the last crashes, I noticed, that I changed resolution to my projector and the game crashed. Changed the resolution back and the game work for a little bit. I have played with that resolution setting for hours before and had no issue. If its not one thing is another with DCS. I tried numerous things including reinstalling DCS, Windows (back and forth between 10 and 11), Drivers. I have set my page file, run as administrator, set DCS app to high performance in windows and nvidia control panel. Spent more time probably trying to fix DCS and get it working then flying at this point. This game is so awesome and I love flying, but its getting close to wanting to give up on DCS altogether. The these crashes are on start up, never while playing. It never gets past the LOGO on startup. Doesn't go black, just Logo pops up and then after 5 - 20 secs crash advisory window pops up.

I know DCS is a delicate game and seems numerous people have so many of the same problems while others no problems at all. 

I'm not sure if its the same issue or a different one at this point but can someone take a look at these crash files and let me know if anything sticks out to them or something I should try. 

info on my pc:
RTX4090, AMD Ryzen 5950x, 64gb of ram, ROG Crosshair VIII Formula MOBO, 1200watt PSU, 5 virpil hotas and panel devices (powered by USB hub), Winwing MIP( consisting of 4 devices and 3 MFD screens. Powered through USB HUB). TrackIR w/pro clip. DCS open beta (i had numerous crashes when on stable too)

Thanks everyone,

Cheers.

Hi. It seems DCS is having trouble detecting your GPU. You should see this:

2023-02-15 22:01:27.080 INFO    GRAPHICSVISTA (Main): renderer: 'dx11backend.dll'
2023-02-15 22:01:27.155 INFO    DX11BACKEND (Main): DX11Renderer initialization (w:2560 h:1440 fullscrn:0 vsync:0 adapter:0 monitor:0 shaderErrors:1)

but you're seeing this:

2023-02-14 23:01:29.457 INFO    GRAPHICSVISTA (Main): renderer: 'dx11backend.dll'
2023-02-14 23:01:29.972 INFO    DX11BACKEND (Main): DX11Renderer initialization (w:2560 h:1440 fullscrn:0 vsync:0 adapter:0 monitor:0 shaderErrors:1)
*CRASH*

It makes me think of two possible issues:

• an internal GPU popping its head at an inappropriate moment
• a GPU driver issue

If your motherboard has an internal GPU and you have no use for it, the easiest thing to do is to disable it in the BIOS. If you don't want to change your BIOS settins, you need to tell both Windows and your NVIDIA drivers that you want DCS to use your RTX4090 and nothing else.

Follow this guide: https://www.addictivetips.com/windows-tips/force-app-to-use-dedicated-gpu-windows/

If your issue persists after this, uninstall your GPU drivers using DDU, then install a fresh NVIDIA GPU driver.

Hello Flappie,

Thanks for the reply, I appreciate any help on the matter. I have some updates from trying out your suggestions. First a little info.

After posting this thread, I was in the process of numerous windows resets and  subsequent installations of DCS and drivers. After a few attempts, everything seem to work fine. An interesting issue popped up on the last two installations which was the SimApp Pro application used to configure and output game MFDS to the MIP MFDs had an error on start up which was a bunch of gibberish to me but a quick search on Winwings support page showed that I just needed to reinstall Microsoft Visual C++ Redistributable (x86) & (x64). which is weird only because that was one of the first problems I had with DCS popping up a cruchtime. error message on start up. That has yet to be a problem with DCS for sometime now and even though the Sim app pro app was not working requiring the reinstall, DCS was. 

So, after all that DCS ran fine for yesterday afternoon. I went to work shutting down my computer, and when i woke up this afternoon DCS crashed on startup. I checked this thread and noticed your reply so I checked the BIOS and could not find a option for internal GPU, I also did a google search and skimmed the manual for any sort of reference to an internal gpu/discrete graphics. I could not find any. The Motherboard I'm using is a ROG Crosshair VIII Formula with a 1200w PSU. I downloaded DDU and preformed a Clean & Restart while in windows safe mode.

Game still crashes on start. I opened up the installer for Microsoft Visual C++ and preformed the repair function. Still no change. I deleted the DCS saved games folder. Still no change.

I have attached the new logs, and crash files through out the mentioned troubleshooting, after seeing your suggestions. I have loaded them in the order I have been starting DCS.

I'm going to see if I can get a computer tech to confirm if my motherboard, RAM etc has been compromised. 

Thanks again for for your help and any continued support.

Cheers,

I confirm your motherboard has no internal GPU.

Here's a list of solutions that might help:

Add DCS main path as an exception to your antivirus software.

Ensure Windows power plan is set to default or high (anything but low energy mode).

Uninstall Dolby DAX Atmos driver if you have it on your PC.

If you're still stuck after this, open a support ticket: log into DCS website, click "Support", then "Create a new ticket".
