Europa Universalis IV Dev Tracker

Is it the game or the launcher that won't run? Because there is an issue with the new launcher where it won't run on older OSs now.

If that is the situation, can you update your macOS?  

Maybe the Chrome thing is a red herring ... what if you revert to a previous game version?  

I'm on an Intel iMac from 2017, MacOS 13.6.1  

I've just updated Chrome to Version 119.0.6045.105 (Official Build) (x86_64) and EU4 still works fine for me ... all I can think of is there's a problem with Chrome on your Mac. No real idea what to do about that I'm afraid!

Does CK2 work okay? It is free to play on Steam now.  

It's been confirmed that the launcher will no longer work on WIndows 7, and never will any more.

In order to run an older version of the launcher, the easiest way to do it is to rename the folder of the version you want to keep (in this case %LocalAppData%\Programs\Paradox Interactive\launcher-v2.2023.13.1) to instead be named launcher-v2.2099.99. This will cause it to be chosen as the latest version. Launcher updates should subsequently fail - Which is probably what you want.

Good luck!  

Any fps of 20 or more ought to be adequate for a non-acton game like this. Stuttering however is a problem of course.

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:

I guess everyone has updated Chrome like that but are not getting that error - myself included!

Mine is Version 118.0.5993.117 (Official Build) (x86_64) , what do you see?  

Try editing that settings.txt. as follows

refreshRate=60
fullScreen=yes
borderless=no

vsync=no

AND make sure your AMD drivers AND Mesa are the latest available. Any better?  

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!  

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.  

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

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.

A-Dash said: Sorry to disturb this old thread but did you ever find a solution to this problem? I recently switched to a 2k monitor and did a reset of my computer and now all my paradox games have a stutter/drag every time a day ticks. I also made a thread about it here without much answers to a solution. If you did find a fix I would be very grateful if you told me.

Please don't re-open old threads, nor post your problem around multiple threads and forums - it won't help get your problem fixed any faster!  

I'm not sure I trust those temperature readings. Can you check with different apps please? CPU-Z, GPU-Z, and Speccy might help with that.

If you still see temps over 80c, that is your problem. What actual fps are you seeing in the game?


The settings.txt you attached here does not match the one in your screenshot.

Please update that nVidia driver:

Please start your own new thread! In there give full problem history and system details. Thanks.  

No clear cause of this problem in those files.

There's a crash in an nVidia utility in there though; did this first happen after an nVidia update, or some other change or update? Or has it never worked on this machine?

What if you make a new Windows user on this machine and log into it with that - does it work there?  

There's no mention of this game in that dxdiag, which means the game never even got started.

You seem to have pasted the contents of dxdiag.txt into the pdx_settings.txt file. Delete that file and try the game again, does it make a new one?

And, is there a "Documents/Paradox Interactive/Europa Universalis IV EGS/logs" folder? If so what is in it?


On an unrelated issue, your machine is badly configured:

Memory: 16384MB RAM
Available OS Memory: 14284MB RAM

2gb of your 16gb is wasted, probably the AMD Vega 8 video is set to use those memory addresses. There will probably be a bios/firmware setting to address that.  

What fps are you seeing in the game now? It should not get over 60.

Please:

- expand your Windows paging file maximum size to 32gb

Optional: Increasing the paging file size on Windows computers

On computers that have 8 GB of RAM, the suggested paging file size is 16 GB. ... Read more

Yes, if you get some error when doing that we need to know what it is!

Otherwise :
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 .  

I assume this is using a mod in either EU4 or CK3 to do this conversion? If so you need to contact the mod author(s) on this issue,.

Good luck!
