Camera Choppyness and Stutter in 2.6.1

[Crimsonlyger]

This solved the issue. The game is running smooth as butter again. You are actually my hero. Thank you!

Can you explain how you fixed it? I don't see the same options in my task manager.

Edit: I found the settings, and I picked my highest use core, disabled, and re-enabled while the game was running and no joy.

Okay, i'm going over some tests with msi afterburner and double checking the resource monitor - hopefully this is of some use for you guys:
one of my cpu cores is locked 95%-100% usage while the others range from 5% to 20%
(i'd also like to add that i did have chrome with 20 tabs open at the same time so its not a perfect test)
I havent had the chance to test with an older version (that dont have the stuttering issue) - will get to that tomorrow.

---update:
disabling and re-enabling the core from task manager >> process >> affinity
seems to have fixed the issue for now

Well that is an amazing fix!

@Guraan does this tell you something?

 

[Roflknifer11]

So does this potentially mean it has something to do with how the game is now utilising CPU cores?

- So it would seem for the moment
Unless someone else has a better sounding explanation for it, i'm just going here with what i've tested and experienced, and read from different forums too

There was a small update yesterday to 2.6.2 - the issue is still persisting but the workaround with the cpu affinity still works too.

This solved the issue. The game is running smooth as butter again. You are actually my hero. Thank you!

- Haha, you're welcome; glad to hear its working for you as well!

-Hey, hmm how many virtual cores do you have?
I had the initial problem of not turning the actual right one as they are numbered differently in task manager and MSI Afterburner that i used.

So, just to confirm - you're here -

you changed the affinity (disabled the core and hit ok - this closes the window)
for me it was the seventh core - which is cpu 6 in task manager but you could also disable the ones around it.
Or you can even disable all but one.
Just while doing this change.

and then open it back up, mark the checkbox and hit "ok"

The way im making sure there is no choppiness afterwards -

open the "load game" section, only hover over the "load last save" box and observe if the orange line is moving smoothly or skipping like 1-2 seconds
lol

Can confirm this fixes the problem. Mine was core 5

However I do get the problem where another CPU core suddenly goes to 100% after this, so choppiness comes back.

Hope there is an official fix for this soon

Is there any way to lock the affinity settings for Stellaris or will we have to keep disabling cores every time we play? Obviously it’s not the end of the world and I’m just grateful to finally have a fix.

 

[Roflknifer11]

Hey guys are you also running on 2.6.2?

Interesting is that maybe the first time after the update i had to bounce the cpu core; but afterwards the issue got resolved for me (permanently?)

I havent really done any changes on my pc

 

[Guraan]

Okey, first of all: sorry guys for not replying before now... but when @AndrewT pinged me about this in the beta chat i was just so stunned and had to do tons and tons of googling.
Second: my god @Roflknifer11 you should have so much creds for finding this out.
Third: (this is the downer) Stellaris as an application does not handle the mapping between "hardware threads" and "software threads", this is entirely done by your OS, drivers and/or applications like msi afterburner.
So why 1 core is "clogged" is still a mystery for me, might be something in the stellaris threading code that encourage Windows (this does not seem to be an issue on linux nor osx) to just utilize 1 core (i do not doubt this tbh).
But question to you all that have solved the issue with "affinity":
Are you all running hardware throttling controlling software (as msi afterburner or similar)? Does the issue still remain if you disable it?

Hi Gurann,

I can confirm that my problem gets fixed with Affinity (mine is core 5). I do have MSI afterburner installed, but problem occurs despite MSI Afterburner not being on

Thx for the reply, i honestly did not think so either but since afterburner + nvidia drivers have had troubles in a somewhat similar way (read some old battlefield forum post) i had to ask O
So now when we have ruled out that we are gonna rule out 2 other things:
First, i want you guys to run the game with opengl as backend renderer instead of dx (this is because dx spawns alot of threads itself, think ogl on windows is more restricted)... this is done by adding the launch option `-opengl` and it is not really supported on windows so it might crash or give you graphical artifacts.
Second, change the amount of workers executing threaded work: open the ingame console and type `Threading.TaskThreadCount`, this will show the current amount of workers. If the number you c is >4 divide the number with 2 and if that <number> is higher than 4 do `Threading.TaskThreadCount <number>`

Pls get back to me if it works or not O

Ok not sure how to do the first one. But I did the taskthread count.

Intial number was 10. I reduced it to 5 as per your instructions. It improved the stuttering, not eliminated it. I tried number 2. This eliminated the stuttering.

 

[AndrewT]

Ok not sure how to do the first one.

In your Steam Library right-click on this game and choose Properties. Click on Set Launch Options, and paste this in there:

-opengl

Wait...

I tried number 2. This eliminated the stuttering.

So you went down to `Threading.TaskThreadCount 2` and that worked?

Edit: Pls check the opengl option as well since this is not sane at all

 

[Crazed Heretic]

My Initial number was 15 lol. I reduced it to 7 and then 2. there is still the stuttering

 

[Deadles]

The thread is already over two years old but could the problem be fixed?

 

[Crazed Heretic]

ya would be cool if we could get a fix kinda makes the game very hard to play and enjoy

Given over 2 years have passed, you two may or may not have the same problem now. Did the above workarounds help you?

 

[Crazed Heretic]

Not sure if its the same problem but it seems most similar to mine. The above workarounds did not work. This only started when I got my new computer.
specs:
AMD Ryzen 7 5800X
AMD X570 Chipset
RTX3080
32 gb ram
game is installed on an ssd
computer runs everything great except or stellaris
same issue with or without mods

Then I suspect the cause of your issue is unrelated to the one discussed in this thread.


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 .
