[2022] Why is my game so slow? (tech question)

Has it always been like this for you? Or it was okay up to some point?

Is it like this right from 1444, or only in mid or late game play? Or only after playing for a period?

Is the slowness in load time, time passing day to day, jerkiness in zooming or scrolling the map? Or all of these?


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/EU4/settings.txt and pdx_settings.txt .
From your Documents/Paradox Interactive/EU4/logs/ folder, attach here system.log , error.log .

Did it just suddenly get slow from one day to the next, or gradually?

Either way, was it after some particular game, Windows, driver or hardware update?


First, update that nVidia driver to late November 2022 https://www.nvidia.com/Download/index.aspx?lang=en-us

Then unload GeForce Experience if running.

Edit that settings.txt to say:

refreshRate=60
fullScreen=yes
borderless=no

vsync=no

THEN 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

Then test with a new campaign, not any existing one. Any better?
