[2023] game crashes every 30 minutes

Update that nVidia driver to June 2023 https://www.nvidia.com/Download/index.aspx?lang=en-us

THEN Right click on ck3.exe , properties, compatibility. Tick "disable fullScreen optimisations" untick every other box in that dialog, Apply and exit.
Then in the launcher Game Settings menu, select fullScreen display mode, Vsync off, cap refresh rate at 60.


If those don't help:

Please attach here your Documents/Paradox Interactive/CK3/pdx_settings.txt .
From your Documents/Paradox Interactive/CK3/logs/ folder, attach here system.log , error.log , exceptions.log

Oh, is this all in one campaign? What if you start a new test one, does it happen there too?

Any mods involved in it?

Is the crash repeatable from its saved game, or when you reload it goes past the point where it crashed before?

What fps do you see in the game?  

I am sorry, I see no reason for these crashes in any of those files.

These crashes are only happening during a save game operation, are you saying? What antivirus app do you use? Make sure ck3.exe is in all its exceptions lists, AND that it is not doing realtime scans of Steam/SteamApps/common/CK3 AND Documents/Paradox Interactive/CK3 folders.  

It is hard to understand how video settings could cause a crash when you go to save a game, they are really unrelated things!  

You are getting two kinds of crashes now? One on save and a separate one related to video settings?  

That seems to be saying it is running out of Vram, which seems unlikely with your hardware!

If you select Vulkan instead of DX11 in the launcher-game settings menu, do you still get this?  

What errors does the log show now?
