Please go here:
support.microsoft.com

Latest supported Visual C++ Redistributable downloads

This article lists the download links for the latest versions of Visual C++ Redistributable packages. support.microsoft.com And run the x86 and x64 installers there.

IF that doesn't help, 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

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 , exceptions.log

You ran both those VC++ installers? Any issue doing so?

May as well update that nVidia driver to August 2022 https://www.nvidia.com/Download/index.aspx?lang=en-us


If that doesn't help, 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, refresh rate 60.

Is that any better?

iAura said: Sidenote I can't even get into the game to change the refresh rate.
This is done in the launcher, not the game, as I mentioned. Please try that.

This problem is nothing to do with .NET as the game does not use it (only the launcher does).

So far we have 0 clues as to what is wrong on this machine to affect our game this way. Clearly something changed between when it last worked and first had this problem, but I cannot see what.

What if you make a new Windows user on this machine and log into it with that, any different?

Running ck3.exe does bypass the launcher completely. Your problem is nothing to do with the launcher.

Is the Documents/Paradox Interactive/CK3/logs/ folder still empty?
