[2021] CK3 is overheating my GPU and shutting down my new PC !

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  

That system.log shows you running game version 1.3.0 - is that right? Current is 1.4.4

And I see Window 10 has not had major updates applied for nearly 2 years. While unlikely to be the cause of this problem, you really should run Update and apply the new Win10 version you see there.

With those settings you should max out at 60hz which should not cause overheating. What fps do you see in the game?  

Well, if it's overheating at less than 50 fps there is something severely wrong , maybe a broken fan or old thermal paste in the GPU?

One more thing to try; edit that pdx_settings.txt and change this line as follows:

"renderer"={
version=0
value="OpenGL"
}

That is case sensitive, so exactly like that please. Does that make any difference?  

Ah, you said it was a new machine, so it won't be old thermal paste then. You might need to get the hardware checked out, maybe they even omitted it?  

You can limit frame rate, but not GPU % as such. Believe me we'd know if this was happening to everyone!

In the game settings in the launcher set it to fullScreen, vsync off, and refresh rate cap to say 60.

If that doesn't help you may need to use GeForce Experience to do that.  

Please do not re-open old threads here, always make your own new thread in future.


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:
