Crusader Kings 3 Dev Tracker

The Geek Cupboard said: have a save game that started on version 1.5 but I then continued playing on version 1.6.

That will be the problem I'm afraid - those two patches are not fully save game compatible. The intent was you revert to 1.5.1.1 to finish any existing campaigns.

If it's not an Ironman game you can still do that, if you still have a save that was last saved under the 1.5.x patches not the 1.6.x ones.  

If this only started happening 2 days ago, it seems unlikely to be due to game bugs as the game has not changed for weeks.

Is this all in one particular campaign, or also in any new one you might start? You mention mods - are there any involved?


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, exceptiosn.log  

I don't know anything about consoles, I'm afraid!

I guess if there are any networking options in them, try those.  

I did get this from one affected Gamepass user:

In case anyone else had issues when they purchased the season pass from gamepass.
The season pass shows no downloads and the dlc by itself looks like you need to purchase it.
Click the dlc and click the purchase.
It’ll change and say you own this already.
Click the same box that now says you own this already and it’ll ask you to download it.
Do the download and boom it finally adds
You need to do it for both northern and RC downloads.

Please let us know if that helps you!  

I didn't even know that was supposed to be saved, if so where exactly. I gues you can save and load save games okay? Game settings changes such as resolution or sound volume?  

I wouldn't suggest it unless it was of diagnostic help. It distinguishes between a problem on this machine, and something wrong in your Paradox or Xbox account.  

In Documents/Paradox Interactive/CK3 you'll see last_save.ck3 . Copy that file to the /save games/ folder there, does that get you going again?  

Not sure what you mean there, but can you try it on another computer?  

HappyOrganism said: I found more game that crash for me, it might actually be the GPU problem.

I think so too, especially if you still get that error I quoted above. Sorry about that! Probably time to contact nVidia.

Very odd, that usually works. Like the other user here already has, can you try it on another computer?  

P4CH said: I have same situation, CK3 form Gamepass, DLC purchased and installed, but CK3 launcher doesn't see DLC (no DLC card). On another PC it is working fine. Does it mean then DLC from MS Store works only on one PC?

No, it means there's something wrong in Windows on that PC (if you went through my procedure above and it did not help), most likely n the MS store/gamepass/ Xbox account area. I frankly don't know what to even try in that situation!  

There is indeed a problem with your nVidia driver or card:

Fault bucket LKD_0x141_Tdr:6_IMAGE_nvlddmkm.sys_Pascal, type 0
Event Name: LiveKernelEvent

Please try this:

- uninstall that driver and all other nVidia software
- reboot
- install late June 2022 by fresh download https://www.nvidia.com/Download/index.aspx?lang=en-us
- reboot again

Good luck! ... Read more

Looking at that error log it seems to be an issue with the video card or driver, obviously standard settings like that shouldn't crash anything.

Save file? So this is only happening in one particular campaign, is that the case? You can start and play a new one okay?

And, you don't seem to have set the refresh rate to 60 as I suggested? Please try that.  

You say no mods but there are some mod errors in there?

After the crash, can you play on with that campaign or it crashes at the same point?

Is this just happening in that one save game? Or in any other campaign you might play too?

And finally, was this campaign started under 1.6.1.2 or some earlier patch?  

You cannot delete games from your Steam account, only Steam can do that.

It will still be in your Steam library to install and play.  

I merged your two threads.

There is a current problem with mods being recognised on this game, as you can see here

Mods enabled, yet not working after 1.6.0 update.

After I updated to the new 1.6.0 update, my mods ... Read more

I'm afraid your nVidia GTS 250 video system is well below the published minimum requirement, the Nvidia® GeForce™ GTX 660 (2GB) . And its driver has had no updates since 2016, well before this game came out. The CPU is also below requirements.

Unless you have access to a machine with supported hardware for this game, I suggest you seek a refund from where you bought it.

Sorry for the bad news!  

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?
