CK3 crashing a few minutes after starting the game

[RobBertOss]

After starting the game and going to the global map or even during loading the game crashes. I have already tried many ways to solve this problem, but the crashes continue steadily, I played CK3 a long time ago and there were no problems, but bought the game yesterday on a new account faced with this problem


my PC:
CPU ryzen 5 3600
GPU RX 6600 XT
RAM 16GB

If this is on the same PC as before, you may have old data causing the game problems. Try deleting your Documents/Paradox Interactive/Crusader Kings III/ folders

If that doesn't help, this can be a shortage of available memory. Please expand your Windows paging file maximum size to 32gb

AND exit every other app you can before starting the game.

AND 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:
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.
IF dxdiag.txt fails to attach here, rename it to dxdiag.log , or zip it up.

game still crashes

I see you have Windows 11 24H2; this can be the cause of this problem, it seems to affect this game particularly for some reason.

it is a severely broken Windows update that has caused problems across the whole gaming - indeed computer - industry.

A user has come up with another possible workaround

Some affected users have definitely seen that help them with this issue. I'd suggest you look at this step first!

And, switch the game's renderer to Vulkan on the launcher-game settings tab.

The CK3 devs are aware of the issue of course, but I don't know whether it is thought possible to change the game to work around the Windows 11 bugs.

Sorry about that!
