[2021] Game is running slow, even on "fastest" speed

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

- move any valued save games elsewhere, and user_empire_designs.txt from /Documents/Paradox Interactive/Stellaris/ if you have made any custom empires or races.
- "uninstall" in Steam-Stellaris
- unsubscribe from ALL mods in the Steam workshop for this game
- manually delete both the Steam/SteamApps/common/Stellaris AND Documents/Paradox Interactive/Stellaris folders
- re-install game in Steam, run a Steam Verify when done.
- add stellaris.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

In particular you need to make sure there are no files or folders left under either the Steam Stellaris or Documents Stellaris locations, before installing again.


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/Stellaris/settings.txt and pdx_settings.txt .
From your Documents/Paradox Interactive/Stellaris/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

Your C: drive is critically. low on free space, Windows like at least 10% free on the boot disk as elbow room. That may be preventing it paging unused apps out, for instance. See if you can free up another 20gb there.

I don't see any other obvious cause of slowness in those files. There are some crashes in the Radeon software but I doubt that is anything to do with it.

But are you running Catalyst, it may be 'managing' the game for you. Try unloading it if so.

griczzly said: I tried to measure how long it take to pass one year on small galaxy and without mods, with my problem on fastest speed -> 1:41 minutes

On my modest rig the first game year (small galaxy = 400 stars) passed in just under 1 minute.
