[2023] Crash launch game.

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?


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  

[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 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?  

Atumaj said: I greet you and also wanted to inform you that the launcher is not working for me.

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

Atumaj said: even if I want to play without Steam CK3 or Stellaris I can't get into the game.

Are you saying running ck3.exe and stellaris.exe directly from File Explorer also fail? If so that is a separate problem to the launcher not starting. Do they show any error when they fail?
