Crusader Kings 3 Dev Tracker

Is this a Steam or some other edition?

How exactly did you move them?  

Did you cap the framerate too 60 as I suggested? Because that settings file says not!

Once you've done that, what fps do you see in the game before it crashes?


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
SPEEDFAN http://www.almico.com/sfdownload.php   ...

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 , exceptions.log  

If that campaign has been saved under a new patch, you won't be able to play it under an old patch, no. You'd need to use the save game file from before, if you still have it.  

I take it that second video adapter is an integrated Intel one, as its common? What you could do is enable it again and connect the monitor to that, see if it still happens.

And, unload GeForce Experience before starting the game, if it is running.

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.

Does your monitor support G sync or any of that kind of function? If so what is its setting in that regard?


Any of those make any difference?  

You mean a campaign that you started two years ago real-time? If so, you will certainly be having compatibility problems, you would have been on patch 1.3.x or 1.4.x at that time - we're up to 1.9.2.1 now - more than 20 patches later!

If you know what patch you last played it under, you could revert to that game version in the Steam Betas tab for the game.

Otherwise you'd really need to start a new campaign.

All the best!  

Never noticed that option in Steam before, perhaps it is new with their new client. Odd that muuting the Steam webhelper in Windows does stop this problem.

Did that in fact help?  

TuxedoPenguin79 said: That explains a bit. I'm honestly quite surprised, if you have an old spare machine i'd recommend slapping Linux on it to help with support, or just run a Linux distro through a virtual machine.

I do run a VM with Ubuntu 22.04 on it, but that's not going to help you with your problem on Arch. The game loads up fine on it, although the virtual video system is not good enough to actually play.

TuxedoPenguin79 said: Do you have any idea of why the terminal isn't picking up logs on why it crashes, or why the log files aren't being created?

I do not, I'm sorry! My Linuix knowledge is pretty rusty by now, I haven't supported it as an OS for nearly 10 years by this point.

Can you get any technical help from Arch or Garuda sources ? There surely must be Linux logs somewhere that record what happens when ck3 tries to start and fails!  

Did you do the clean reinstall I described? Because that error log looks even worse if anything!

Was there no system.log file?

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.

THEN start a new test campaign. Is that any better?  

What I described was a Windows function, not a Steam one; muting that particular Steam process in the Windows sound system. TBH I'm not sure of the Mac equivalent, even though I'm a Mac user myself.

I can see several Steam helper threads in Activity Monitor but no way to mute them.

This is the best I could find with a quick search

Well, we don't support the Deck either, so ... ! Yet, anyway.  

I am sory, I have no idea what is wrong on this Linux installation to cause this to you. Without any game log files we see no clues anywhere as to even the general area of the problem.

Is there anything of use in the Linux system logs perhaps, that record what is happening as the game attempts to start up?  

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


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'... Read more

As this is happening, alt-tab out of the game . Right click on the Speaker icon in your Windows task bar, open Volume Mixer. If you see the Steam Webhelper in there, mute it.

If that helps, this is a Steam problem in my opinion, caused by their radically new client that installed recently.  

TuxedoPenguin79 said: The file was libtbb.so.2 I was having issues launching it, so I checked ProtonDB, and replacing the file was recommended as a fix, so I tried it out, surely enough, it worked,

You just needed an updated version? That would be odd for a game that hasn't been updated for some years!



When you run ./ck3 from the terminal, what output do you get there?  

Those errors may or may not be anything to do with your crash.

Is this happening in every campaign you play, or just one particular one?

Are there any mods involved here?  

An interesting perspective; I've been using Macs since originally released and have never used an external disk except for backup.

The fact remains, there is something preventing the game accessing what it needs to when run from that external drive! It's hard to see how that could be the game itself; but you could test that by reverting to an older game version that used to work from the external drive.

You could try running a Disk First Aid on all your Mac volumes.
