The game did not change overnight so it's hard to see what could have caused this to you! Most likely something outside the game.

Was there a video driver or Windows update perhaps?


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 that doesn't help, try Vulkan instead of DX11 as the renderer - any better?


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

As Vulkan didn't help, you can go back to DX11 .

Looks like you have an issue with the nVidia driver or card:

+++ WER9 +++:
Détecteur d'erreurs LKD_0x141_Tdr:6_IMAGE_nvlddmkm.sys_Pascal_SCG3D, type 0
Nom d’événement : LiveKernelEvent

Please try this:

- uninstall that driver and all other nVidia software
- reboot
- install late Feb 2023 https://www.nvidia.com/Download/index.aspx?lang=en-us
- reboot again

THEN check for an update for that Intel HD Graphics 630 driver from Lenovo, failing that from Intel https://downloadcenter.intel.com/


Good luck!
