[2023] slowdown in games

When you say "slowdowns in games", which games aside from this one are you referring to?

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 .  

What do you see if you run eu4.exe directly from File Explorer? Any Windows error show?  

You haven't set eu4.exe to run as the Admin user, have you?

Aside from that, I don't know why the launcher will not start the game any more.  

Sorry, I'm not quiet clear - if you have set eu4.exe to run as Admin, undo that please.


Otherwise do a full **clean** re-install:

- move any valued save games elsewhere
- "uninstall" in Steam-EU4
- manually delete both the Steam/SteamApps/common/Europa Universalis IV AND Documents/Paradox Interactive/Europa Universalis IV 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
- if still a problem, implement the settings from post #2 aboev again

Good luck!
