[2021] Can't find solution to Micro Stuttering

I'm already helping you with this in a ZenDesk ticket.  

There was a Windows patch that caused this

Microsoft Fixes Windows 10 Updates That Hit Game Performance

Last week, the Windows 10 updates KB5000842 and KB5001330 made a bit more of a fuss than usual, because they were found to be at the heart of several gaming-related performance issues across various games and graphics cards. kotaku.com
Are you completely up to date in the Windows Update app?  

Palaki said: Yes Windows is up to date. I have this problems since long ago. After initial game release, the game ran very smooth for me, no stutter and stuff it was a pure joy.
It doesnt matter which galaxy size, there is always a stutter at the beginning of a new ingame day which looks and feels terrible. Space battles and overall ship movement feel like a diashow. Its like in OP´s video, but getting much worse the further the game progresses.

Has this always happened with this game for you? Or it was okay up to some point?

Does it affect the similar games CK2 and EU4 also?


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 your Documents/Paradox Interactive/Stellaris/settings.txt and pdx_settings.txt .
From your Documents/Paradox Interactive/Stellaris/logs/ folder, attach system.log , error.log .  

So many errors in that log! I can only assume they are mostly from mods. 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
- manually delete both the Steam/SteamApps/common/Stellaris AND Documents/Paradox Interactive/Stellaris folders
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.
- 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.

The load or start a galaxy with no mods are all, and see if you still have th eproblem. If not please attach new coies of all those files, thanks.

Already did all of this, but to give you those clean files, i did it again.

1. Unsubbed all mods
2. Uninstall the game
3. deleted all those folders
4. reinstalled the game
5. verified game files
6. checked Windows defender, stellaris.exe is on the list

FYI i also never modded CK2 so i dont think its a mod issue.

I really hope you are able fix this problem. This stuff really prevents people who have this issue from enjoying the things you guys added to the game...

Well your log file is a lot better, so that's a good thing in its own right.

I see no other likely cause of this problem in those files. Does it happen in borderless and windowed display modes too? And does it only happen on speed 5, or lower speeds too?

Any OCing done on this hardware?  

supremeonejosef said: Did the same. Still have the same issues. Attached files

The same applies to your info, I'm afraid, no smoking gun in there. The same questions ...


And do you see this in HOI4 and CK2 also?  

Palaki said: Also happens in borderless and windowed display. Every speed, stutters are bound to the daily ticks. faster speed = faster stutter. Slower speed = slower stutter.
CPU is slightly OC, but system runs well overall and in every other game. Temps are fine, too.

Can we test with no OCing implemented at all please?

And can you please run up Task Manager and go into Performance. When this is happening is there CPU, GPU, Memory, Disk and/or I/O usage that moves in time with the stutters/ticks?
