[2023] Game keeps crashing in mutiplayer

Is this crash while playing an MP session, or while starting up the game, or while connecting/loading the save, or what?

Is it just you that crashes, other players are okay?  

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.

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

How does graphics settings can help with the game logic?

Just because you see an error in that log, doesn't mean that's what caused the crash.

If it was a game bug, why does it only happen in MP, and only affect one of the players?  

psvoid said: Currently 1.11 crashes a lot not only in MP, but also a lot in SP. Many bug reports here. One player is affected because he performed necessary actions for the crash.

The OP here only mentions MP crashes, and is the only one in his player group getting them.

If you are getting SP (or indeed MP) crashes, please start your own thread here. Thank you.
