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

Delete that system.log and run the game again. Does it make a new one, and populate it now?

We se no crash in this game in that dxdiag, unfortunately.

From that settings file the frame rate cap is not set - please set it to 60.

If the problem still happens then, what fps are you seeing in the game? What CPU and GPU temperatures just before it crashes?
