[2022] Big performance issues in CK3

Aside from the raw fps numbers, what other symptoms of poor performance do you see? Jerkiness in zooming or scrolling the map? Slow time passing?

And does this happen right from the start, or only in mid or late game? Or only after playing for awhile?

The 1.5 patch was release on Feb 8, but you mention having had this problem in January 2021, is that right? If so it must be something local that changed to cause this to you, rather than a game bug as such.


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


Please report the temperatures of your CPU and video (GPU)
1/ before starting the game up and
2/ after say 10 minutes' play.
If your PC's vendor has given you no way of reading temperatures, install

Lord Victor said: I can't, because I've unninstaled the game and erase all the data files, and then reinstalled it like you've said on the other thread.

Those files will be recreated the first time you run the game again ... ?!? Except dxdiag.txt which you need to generate in the way I described.
