[2021] CK3 keeps randomly crashing to desktop

As you can see from that error log there is a problem in the video/graphics area.

DXDIAG is a program you run from the Windows search box on the task bar. After running it will open a window and start collecting info with a progress bar in the lower-left corner. When it completes click the 'save all information' button and save it to a file then attach that file here.  

There are several LiveKernelEvent entries in there. They happen when the machine is forcibly downed or rebooted. Are you seeing those yourself? If so are they related to this game or something else?

The nVidia driver could stand updating so let's go a clean reinstall of it:

- uninstall it and all other nVidia software
- reboot
- install the latest from here:
Download Drivers | NVIDIA - reboot again

Good luck!  

That error log looks much better , we've definitely fixed a video driver issue.

I see a mod error though - you are doing all this testing with no mods at all enabled, is that right?

After it crashes can you start right up again? Or do you need to reboot, or wait a while, before the game will run?


Please report the temperatures of your CPU and video (GPU)
1/ before starting the game up and
2/ after say 10 minutes' play.
If your PC's vendor has given you no way of reading temperatures, install
SPEEDFAN http://www.almico.com/sfdownload.php  

Not an overheating issue then.

But some of those video errors have come back, which is very disappointing. Not sure what to make of that, to be honest.

Let's try running the ame in other modes. Edit that pdx_settings.txt:

"renderer"={
version=0
value="DX11"
}

Please try DX9 and then OpenGL in that section - to be honest I'm not 100% sure what the right format for either is, if neither of them work I'll have to run this past my Manager in Paradox.  

Apparently there is no DX9 option any more, but OpenGL has been tested to work. It is case sensitive so paste that in exactly.  

Is performance acceptable?

Whether there is some obscure bug in the game vs DX11 that affects you, or some Windows issue here, is not at all clear to me I have to admit.  

gtigers55 said: I've been having the exact same issue as the guy above. I tried what you did with his to fix it but that didn't work (actually worked worse) Attaching my dx diag.

EDIT: Added error log.

In future please start your own thread - similar symptoms do not necessarily come from the same root cause.

Your problem comes from your nVidia driver:

Windows Error Reporting:
+++ WER0 +++:
Fault bucket 1777952510989485488, type 5
Event Name: BEX64
Response: Not available
Cab Id: 0

Problem signature:
P1: ck3.exe
P2: 1.0.0.0
P3: 60d4415a
P4: nvoglv64.dll

and it is not up to date. Please try this:

- uninstall your nVidia driver and all other nVidia software
- reboot
- install the latest October 2021 from here:
Download Drivers | NVIDIA - reboot again

Then test with a new unmodded campaign. Please us know if that helps or not.
