[2021] I think i need some Help

That is an issue with Windows 10 and certain nVidia setups. We've never been able to determine why it affects who it affects. It has come and gone a couple of times in the last couple of years.

You can just play in borderless mode, it is essentially the same as fullScreen.

All the best!  

So it works in windowed mode but not borderless or fullScreen? Because I don't think I've ever heard of that situation before.

Has it always been like this, or it was okay up to some point?

Does this affect CK2 also?


DXDIAG is a program you run from a command prompt or the Windows start menu 'run' dialog box (or 'search programs' in Windows 7 or later). 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 your Documents/Paradox/Stellaris/settings.txt and pdx_settings.txt .
From your Documents/Paradox/Stellaris/logs/ folder, attach system.log , error.log .

But you said

Sorry if I misunderstood you!

I ask because you have Windows errors in that dxdiag I haven’t seen before, InPageError . I wonder if you have a Windows or hardware problem.

what happens if you exit the Steam app completely and run Stellaris.exe directly from Windows Explorer?  

Mekhet_Azrael said: When I start Stellaris without steam, with the exe in documents, it starts but without the launcher.

It runs fine when started that way, is that right?

When you run it from the Steam PLAY button, do you see our launcher at all? If so what version does it show?  

Please try this:

- exit the Steam app entirely
- uninstall Paradox Launcher v2 from the Windows "Apps and features" utility, if still present.

Delete the following folders if still present:

- C:/users//AppData/Local/Programs/Paradox Interactive/
- C:/users//AppData/Local/Paradox Interactive/
- C:/users//AppData/Roaming/Paradox Interactive/launcher-v2/
To see the AppData folder you'll need to enable View Hidden Items in File Explorer.

- run steam.exe as the Windows Admin user

- run the game from the PLAY button in Steam

IF that doesn't help, in this folder are some .log files:
C:/users//AppData/Local/Paradox Interactive/launcher-v2/
Please attach them here.
