[2021] CK3 Forcing Computer Restart Crash

FYI there is no need to keep posting error logs, they contain nothing about hardware crashes like this.

The game crashes in that dxdiag are still in the nVidia driver, which is surprising - you did do the clean reinstall of all nVidia software that I described before?

Indeed there is a crash in NVDisplay.Container.exe there, nothing to do with this game. That really looks like an nVidia software or hardware issue!  

Weird that system memory (apparently) affected the video like that ... in any case glad you got there, all the best!
