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

Several mod errors in there. Do make sure you disable all mods while we work on this.

Please update that nVidia driver to June 2022 https://www.nvidia.com/Download/index.aspx?lang=en-us

Then right click on ck3.exe ,properties, compatibility. Tick "disable fullScreen optimisations", untick everything else in there, Apply and exit.

Then run the game and in the launcher Game Settings menu set display mode to fullScreen, Vsync off, refresh rate 60. Is that any better?

So it's not bricking your whole computer any more, is that right? That's some progress if so!

And the crashes now are when saving? Or just autosaving?

Is it anything to do with going into the throne room perhaps?

If so try this workaround

CK3 - PC Update

What antivirus app do you use? Make sure ck3.exe is in all its exceptions lists.

8gb ought to be enough, but do make sure you unload everything else you can first.

BTW how are you determined it is memory? Checking with Task Manager perhaps?

Half your memory is free there, so I doubt that is your issue.

And 80% CPU usage means 20% idle, again that should not be a problem. You might go into the Performance tab though, see if one CPU is pegging out.

Your Intel(R) Pentium(R) CPU G4560 @ 3.50GHz is about the same performance rating as the game's minimum requirement, the Intel® Core™ i3-2120.

Again in that shot we see there is some spare capacity in the CPUs overall, but not the details per CPU. For that you need to click on Open Resource Monitor there, then on the CPU tab.

I still doubt this is the cause of your crashes though. Is there any particular action or event in the game that seems to trigger it, such as going into the throne room? Because that is a current bug.

We can only see 2 of your 4 cores in that shot. Are any pegged to 100%?
