Has this game ever worked on this computer? Or never yet?

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

Edit 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 , exceptions.log

I've been able to play on this computer yes, last time I played was in November with no issues. Changing the settings did not resolve the issue.
There was no such file as exceptions.log in that folder, but here are all the other files:

We see no crash in the game in that dxdiag, which tends to point to a cause outside the game. But I don't see a reason for that either!

What happens if you run eu4.exe directly from File Explorer? That bypasses Steam and our launcher.

What antivirus do you use? Make sure eu4.exe is allowed through all its exceptions lists.


If none of that helps, make a new Windows user on this computer and log into it with that - is it any better there?

I got the game working! I looked at the forum and saw the exact same issue which was caused by RTSS and unloading it fixed the issue.
