[2023] Eu4 stuttering with slow speed

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 .


Please report the temperatures of your CPU and video (GPU)
1/ before starting the game up and
2/ after say 10 minutes' play.
If your PC's vendor has given you no way of reading temperatures, install

It's hard to understand why EU4 sees this and CK2 does not - they are very similar under the covers.

But if this has only just happened, Please do a full **clean** re-install:

- move any valued save games elsewhere
- "uninstall" in Steam-EU4
- manually delete both the Steam/SteamApps/common/EU4 AND Documents/Paradox Interactive/EU4 folders - In particular make sure there are no files or folders left under either the Steam EU4 or Documents EU4 locations, before installing again.
- re-install game in Steam, run a Steam Verify when done.
- add EU4.exe to the exceptions list of your antivirus app; ESPECIALLY if you have Windows Defender, add it to the Ransomware "Apps Allowed Through" list.
- start the game with no mods active and test with a new campaign, NOT any existing one.

Is that any better?  

This smells of a Windows or hardware problem to me, although why only this game I cannot say.

Make a new Windows user on this machine and log into it with that. Do you still get that same pattern?  

Anyone new posting here Please do a full clean re-install:

run the game up to the main game menu then exit to the desktop again (to create the settings files)


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

THEN edit Documents/Paradox Interactive/EU4/settings.txt as follows:

refreshRate=60
fullScreen=yes
borderless=no

vsync=no

THEN run the game from the Steam PLAY button, and in the Game Settings menu there choose fullScreen, and start the game. Test with a new campaign at this point.

Is that any better?  

If you want the developers to look at this you'll need to post in Bug Reports forum - they do not read this forum.

And it will have to be a game with NO mods used in it ever.
