[2022] CK 3 : Screen will go black, but everything still running

That system.log show you still on patch 1.5.1 . In Steam opt out of all betas for this game so 1.6 applies.  

Please do a full **clean** re-install:

- move any valued save games elsewhere
- "uninstall" in Steam-CK3
- manually delete both the Steam/SteamApps/common/CK3 AND Documents/Paradox Interactive/CK3 folders
- re-install game in Steam, run a Steam Verify when done.
- add CK3.exe to the exceptions list of your antivirus app; ESPECIALLY if you have Windows Defender, add it to the Ransomware "Apps Allowed Through" list.
- start the game with no mods active and test with a new campaign, NOT any existing one.

In particular make sure there are no files or folders left under either the Steam CK3 or Documents CK3 locations, before installing again.




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  

We see several Windows errors at thje end of that dxdiag. Are you having issues outside this game, would you say?

Does the Windows Update utility find anythign to apply? If so do that and reboot.

In the launcher Game Settings menu select display mode fullScreen, Vsync off, refresh rate 60. Is that any better?  

Can I get new copies of dxdiag.txt and pdx_settings.txt please?


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

That will be the problem, for sure. I'm surprised capping the refresh rate to 60 has not helped that. What fps are you seeing in the game?  

I don't know thenn. Does reducing resolution from 3440x1440 help at all? Disasbling character animation?
