[2022] Game crashes seemingly at random.

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, refresh rate 60.

Is that any better?  

The only difference between the Steam and MS versions is the MP code, so I don't think that's the issue here.

Did you try it in fullScreen mode as I described? I'm not clear from what you say.


If so please attach new copies of all these files:
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  

Definitely a video issue:

[22:00:39][gfx_dx11_fence.cpp:32]: D3D error: hr returned: The GPU device instance has been suspended. Use GetDeviceRemovedReason to determine the appropriate action.


[22:00:39][pdx_assert.cpp:612]: Assertion failed: hr returned:
The GPU device instance has been suspended. Use GetDeviceRemovedReason to determine the appropriate action.


[22:00:39][gfx_dx11_master_context.cpp:746]: Failed creating fence

There's a slightly newer video driver now so let's do a clean reinstall of that:

- uninstall it and all other nVidia software
- reboot
- install August 2022 https://www.nvidia.com/Download/index.aspx?lang=en-us
- reboot again

And test with a new unmodded campaign - any better?
