[2020] Random game crash

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:
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.

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  

"setting_framerate_cap"={
version=0
value="off"
}

Did you try to set the framerate cap? If not please do that.

If so, what fps are you seeing in the game before it crashes?


LOTS of mod errors in those logs - please do ALL testing on this issue with all mods disabled, and use campaigns that have never had any mods used in them. Thanks.

And make a new dxdiag.txt for me please, but this time wait until it has finished loading before making the text file. Thanks.
