Crusader Kings 3 Dev Tracker

The game did not change overnight so it's hard to see what could have caused this to you! Most likely something outside the game.

Was there a video driver or Windows update perhaps?


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, cap refresh rate at 60.


If that doesn't help, try Vulkan instead of DX11 as the renderer - any better?


If those don't help:

Do these games start from ck3.exe and stellaris.exe okay? If not is there an error shown?  

I missed something before - that systems.log shows you are on an old game version 1.4.4

Royal Court was released alongside patch 1.5 and cannot work on any version before that.

If you've chosen to stay on 1.4.4 for some reason, perhaps mod compatibility, you'll need to disable Royal Court before you run it.

Otherwise you'll need to opt into a later version, or opt out of all betas to get into the current version.

All the best!

In the cpatch log we see:

2023-03-02 01:47:17 [repository] [WARNING] failed to make metadata path repository.json world writable: failed to chmod C:\Users\Mr\AppData\Local\Programs\Paradox Interactive\launcher\.cpatch\launcher-v2-bootstrapper\repository.json: No mapping between account names and security IDs was done.

Are you sure you ran steam.exe as the Windows Admin user?  

I see. For diagnostic purposes can you please make a new Windows user on this machine and log into it with that?

If you still get this problem please attach new copies of all those files; I particularly want to see if you get those same errors in that log. Thank you.  

I see, so when you said "the game will start in the launcher" and "Now everything works as usual.", you meant it was not working?

In this folder are some .log files:

Please attach them here.  

Atumaj said: Now the launcher will be automatically installed again and the game will start in the launcher where everything is displayed with the DLC, settings and news from Paradox.

So launcher and games work okay under 2022.12 ?

Then your problem is unrelated to the one discussed in this thread. In future please make your own new thread, thanks.

There is a UI scaling slider in the game, does that not work for you?  

The power of the computer has nothing to do with games crashing at start. That can only be a game bug or a problem in the computer/Windows, and it cannot be the first option or it would crash on both your machines!

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

In general, any corrupted computer file is probably irrecoverable. But it is not impossible the corruption is relatively minor and can be edited out. The good folks in the User Mods forum here are probably your best hope for that.

However it's a huge worry that it happened to them all at once, I struggle to come up with any explanation for that! Normally only a save for the campaign that is currently open could be corrupted by, say, a game bug or a computer glitch. Save game files not currently open ought to be unaffected by anything like that.

It is probably worth making a thread in Bug Reports and attaching ALL the affected save game files there, with an explanation of the circumstances.

Sorry this happened to you, whatever the cause!  

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.

Good luck!  

That error log does look like a bad game installation, but it's hard to see how that can be after a clean reinstall.

Are there definitely no mods in play here?

CK3.exe should never be set to run as Admin, that causes problems in its own right.


Do you get this on another machine, or under a different Windows user on this machine?  

Local save files are in Documents/Paradox Interactive/CK3/save games/ folder; your save files are physically present there, are you saying? If so the only known reason why the game would not show them is if they are so corrupted the game cannot recognise them as valid save files; how that could happen to multiple saves at once I have no idea.

Also there is Documents/Paradox Interactive/CK3/last_save.ck3 , if you copy that to the /save games/ folder does that load?  

[13:14:44][include_vulkan.h:59]: Gfx error: ResultValue.result returned: ErrorOutOfHostMemory
[13:14:44][pdx_assert.cpp:612]: Assertion failed: ResultValue.result returned:
ErrorOutOfHostMemory

I see you are running in Vulkan , is there a particular reason for that? What happens if you switch to DirectX 11?

And, did you cap the refresh rate to 60? It doesn't look like it in that pdx_settimgs.txt file.  

The game is multithreaded, as are all our recent games. But not all processes gain from being split across processors, so it is common for one CPU to carry more load than the others do. That has nothing to do with your overheating issue though.

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, cap refresh rate at 60.


If those don't help:
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  

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, cap refresh rate at 60.


If those don't help, has the game ever worked on this machine? Or never yet?

What happens if you run ck3.exe directly from File Explorer?

No obvious cause of this in those logs. But was there no cpatch.log there as well?
