Why EU4 stutters above 60Hz Refreshing Rate?

[RealScaletho]

I have a very good PC which is capable to perform smoothly Starfield, Red Dead Redemption, No Man's Sky, COD (2023), Assassin's Creed Valhalla and dozen of way stronger games than EU4.

So why this game seems incapable to perform without hellish stuttering above 60Hz Framing Rate??? Every time I want to play EU4 I need to dumb my Video in order to create a smooth experience. WHY?

I really don't understand why this happens.

Possibly because it's more than 11 years old, and 60hz was about it when it was written ... also, as a non-action game there is no visual benefit to higher refresh rates/fps anyway.

Anyway, let's see if we can improve matters for you. Right click on eu4.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.



IF that doesn'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.
