[2023] Game performance problem.

Sometimes GeForce Experience makes things worse. If you unload it before starting the game is it any better?

And, does this also affect CK2, CK3, HOI4 and Stellaris?


Right click on eu4.exe , properties, compatibility. Tick "disable fullScreen optimisations" untick every other box in that dialog, Apply and exit.

Edit that settings.txt to say:

refreshRate=60
fullScreen=yes
borderless=no

vsync=no

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.

Please attach here your Documents/Paradox Interactive/Europa Universalis IV/settings.txt and pdx_settings.txt .
From your Documents/Paradox Interactive/Europa Universalis IV/logs/ folder, attach here system.log , error.log .  

A few mod problems in there! Please do all testing for this problem using campaigns that have never had any mods used in them, thanks.

Assuming you do have this issue in unmodded campaigns, try deleting the cache and gfx folders under Documents/Paradox Interactive/Europa Universalis IV , so the game recreates them.


If still no good, make a new Windows user on this machine and log into it with that. Any better then?
