[2020] FPS jumps wildly when in game, but stable 144 when tabbed out

If you disable autosaves does this still happen?

Is there a performance hit at the same time as these jumps, or are they purely cosmetic?

Has it happened ever since you've had the game, or just recent patches?


DXDIAG is a program you run from a command prompt or the Windows start menu 'run' dialog box (or 'search programs' in Windows 7 or later). 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 your Documents/Paradox/CK3/pdx_settings.txt .
From your Documents/Paradox/CK3/logs/ folder, attach system.log , error.log  

25/10 is after the most recent patch, FYI.

In those files Vsync is off and the framerate cap is 144 - essentially the same effect as having Vsync on in fact. What if you cap framerate in the game to 60, does this still happen?  

Well, the game has not changed since you posted so unless this is a Windows or nVidia update ... ? Anyway, I hope it stays that way!
