[RESOLVED]DCS 2.5.0 Game Crash

Hello all, I am returning to DCSW after being away for a few years due to the impressive work Eagle has done and the addition of VR. 2.5 looks amazing in the YouTube videos I've seen and I'm eager go rejoin.

Situation:

+Fresh install (I removed and reinstalled the game after the original crashes)

+No external mods of any kind

+The game interface, module manager, logbook, encyclopedia, etc. work without fail

+Any simulation mode: Instant Action, Training, etc. leads to game crash

Actions Taken:

+I followed BigNewy's excellent repair guide

-Cleanup & Repair @ https://www.digitalcombatsimulator.com/en/support/faq/709/

-Crash Guide @ https://forums.eagle.ru/showthread.php?t=202214

-No effect I'm afraid

+I have both renamed and deleted the Saved Games DCS.openbeta folder repeatedly between attempts

Details:

+I've attached the log files and also added the output from DirectX's dxdiag utility to the zip file.

+I've attached a screen capture of the DCS Systems Settings screen (they are the 'low' setting)

+System details may be found in the dxdiag.txt file within the dcs.log***.zip attachment

I am very grateful for both your time and wisdom here - thank you.

This is A Driver/Hardware issue.

Thanks very much SkateZilla. Here are the details for my graphics card and driver:

Thanks again everyone,

Solved.

Noob mistake leaving default nvidia settings on the new card. Thanks again SkateZilla for putting me onto the right path.

Glad you solved your problem so quickly. I see many users with high-end Nvidia cards complaining about DCS crashes. Could you please give us details on how you got rid of the annoying crashes?

Hi ya Flappie, happy to share what I know with the preface that I am no expert. Lots of the folks here know a great deal more than me. But here goes:

Nvidia GeForce --> Verify/Update latest driver

Nvidia Control Panel:

+I borrowed settings wisdom from here: https://www.techporn.ph/basic-nvidia-control-panel-3d-settings-optimization-guide/

+The biggies were:

-Power Management --> Prefer Maximum Performance

-Virtual Reality Pre-Rendered Frames --> 1

I use MSI Afterburner to overclock the TitanX; you can find that here: https://www.msi.com/page/afterburner

I used Heaven Benchmarking from Uniengine to optimize all the Nvidia & MSI Afterburner settings. You can find that here: https://benchmark.unigine.com/heaven

JayZTwoCents has an excellent YouTube video on overclocking (although he uses Evga's software rather than MSI); you can find that here:

Once I got the Heaven benchmark to run on ultra with an average FPS > 78 DCS 2.5.0 would run without crashing. Then I snuck up on the maximum settings within DCS to ensure stability.

Hope it helps,

I'm thinking about creating a post with solutions to the many crash/performance issues players are having since DCS 2.5 happened.

Thank you for your feedback. :)

Just to add that this thread saved my day!

I recently upgraded my GPU from a 970 to an RTX2070 Super. After the upgrade all sims were working great, including P3D v4 and v5 and Il-2 COD at very high settings.

However, in DCS I started having crashes, especially in the F-14 and even on sim startup. I tried all tricks mentioned in the ED forum for crashes (repair, deleting the saved games etc.) but nothing worked. I was disappointed that I had upgraded to a better GPU and could not even fly!

The key was to set the Power Management at Prefer Maximum Performance

I had this set for the 970 but when I changed cards I decided to flush clean the drivers and reinstall them, so I lost that setting and forgot to get back to it. It seems that this caused the power supply to my card to be "optimized" exactly when it was most needed, causing a driver crash. When I did not have a crash I had terrible performance.

After setting this the crashes stopped and I was able to increase sliders to very high settings and DCS runs amazingly well. As a side note, it seems to be better to control MSAA and Transparency Antialising through Nvidia and leave the MSAA setting at 2x in DCS and no SSAA settings. Even though I have a 1080p monitor, I was also able to run at 4k through DSR with no problems.

Happy camper now after three days of grief...
