I'm not aware of a general issue like this, no. has it always been the case for you? Or it was okay up to some point?


DXDIAG is a program you run from a command prompt or the Windows start menu 'run' dialog box (or 'search programs' in Windows 7 or later). 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 your Documents/Paradox/CK3/pdx_settings.txt .
From your Documents/Paradox/CK3/logs/ folder, attach system.log , error.log

Please update that nVidia driver:
Download Drivers | NVIDIA
If that doesn't help, try putting the game in windowed mode in the launcher.
