[Dev Team] 4.0.3 Performance: Request for Saves

[Sanctus Animus]

Getting significant lag with overview open in outliner - switching to ships only increases my FPS from ~25 to ~110, playing as Wilderness with eternal vigilance (all DLCs except astral planes) - slowdown started after i built some more starbases, and those new deep space starbases on top

Having overview with planets open reduces fps even when game is on pause - with megastructures tab i can up the game speed to fast again with no noticeable issues

(4.0.4 -> 4.0.6) 2453 - After the "Unbidden" spawn (~2430), some days took far too long compared to others.
Overall, the relative performance (day to day) is ok - looks more like CK3 normal-ish speed (3/5?). I wish the game could reach a CK3 fast/faster level (4/5?).

I really hope to get a playable late game in Stellaris. The lags are currently keeping me from enjoying the game.
I just want a well optimized DLC. I'll pay.

 

[reberuappu]

i've created a bug report for it as well

this one has me freezing every 2 seconds even when paused ever since i started assimilating psionically other species

Hello!
I have a save with a lot of pops lategame (y2400) and the game speed is really bad. Its ironman but maybe it still helps.

 

[Alalin]

This is my latest game. As I'm sure you can tell from reading the save, it is a 200-stars galaxy, with two regular empires and a fallen one, with the lowest and highest possible modifiers in the respective cases to have the lowest possible amount of pops. I stopped playing around 2280, because in some moments the days would crawl down to more than one second per. Even if it wasn't that slow, it was still not on the same level as at the beginning. I cannot even tell what late-game lag looks like because I never get there. These are my specs:

• Kernel: Linux 6.12.10-76061203-generic
• Display (CSO161D): 3408x2130 @ 165 Hz in 16" [Built-in]
• DE: GNOME 42.9
• WM: Mutter (X11)
• CPU: 13th Gen Intel(R) Core(TM) i9-13900HX (32) @ 5.40 GHz
• GPU 1: NVIDIA Device 2860 (VGA compatible)
• GPU 2: Intel Device A788 (VGA compatible) @ 1.65 GHz [Integrated]
• RAM Memory: 8.49 GiB / 31.08 GiB (27%)
• Disk (/): 218.89 GiB / 928.96 GiB (24%) - ext4

These were extracted using fastfetch, if you need any more I can provide it. I also did some benchmarking. First, using sysbench and then stress-ng.

Got this result from sysbench:

None of my empires save anymore.
Consistent crash. Here's an attachment of a crash that happens consistently (will happen 3 days after you unpause)

 

[Drokslit]

In case ya'll are still taking saves. Got a 4.0.7 beta start game, huge galaxy all the way into 2435. The game has slowed to a crawl.

 

[TLEG_Managarmr]

System Specs:
Arch Linux 6.14.6
SWAY WM (running in Wayland)
AMD Radeon 6950 XT, stock OC curve, running vanilla Mesa drivers
AMD Ryzen 7 7800X3D set to 90C Level5, with -20 curve optimizer
32 Gb RAM, 3200 MHz (can't remember the timings. They're alright)

I can say that on my system I've had buttery smooth performance through my entire game that started on 4.0 and was on 4.0.5 when finished.

The only issues I ran into was the 20-40 second freeze on conquering planets (save already provided in this thread) and the very typical Stellaris end-game lag when a fleet is selected. When a large fleet is selected (180-200 naval size), regardless of if you are in map view or actively watching the system, the game will become a stuttery mess when unpaused. I drop to sub 20 FPS with a fleet selected.

Deselect the fleet and the game is buttery smooth again. While day processing slowed down as the game progressed, it never became SLOW on a relatively default medium galaxy. I saw no crashes and no game breaking bugs.

I am unsure if the planet automation AI bug has been fixed, however, as I haven't started a new game and I didn't find anything about it in the patch notes up until now. If planet automation is on (not the building, the helper AI system) and it wants to upgrade a building, it will start the upgrade process, but once the building is done, it will immediately revert back to it's previous state, and the automation system will then proceed to upgrade it again; endlessly.

Due to my ENORMOUS economy at the time, I couldn't determine if it pays the upgrade cost every time or if it's a "free" broken upgrade. Anyway, the only workaround was to cancel the automated upgrade and press the upgrade button yourself. That worked as expected.

Outside of that:

- 4.0 is smoother than 3.x
- No CTDs
- Planet Conquering freeze (which I've seen no one else mention so I'm not sure if that wasn't just a niche problem on my end. It kept coming and going)
- General slowdown over time was much less noticable
- Fleet UI lag is still there (select big fleet -> entire UI and sim gets stuttery)
- Outside of endlessly attempting to upgrade, planet automation seems alright. Still makes some STRANGE decisions with certain planet designations.

I hope this one instance of feedback helps a bit.

Turns out this one was related to the "you can upgrade defensive platforms" notification on the Outliner.

 

[Felisean]

normal singleplaer game, 1000 Star Galaxy
might be an issue with the mercenary enclaves, if i remember correctly it went down the hill when everyone started building them

in addition, the new starbases behave weirdly when creating more than one type. at least with auto upgrade they all tend do be changed to one of the types overriding the rest

 

[FiddleSticks96]

I have a save that freezes up indefinitely by a certain date every time. I assume that counts as "really bad" performance. The save is attached to the bug report.

Stellaris - Game freezing indefinitely at specific date 4.0.7 open beta [9128]

idk what size galaxy I picked, here's a screen
all speeds run about as fast as normal on start

Spoiler: screen

 

[FiddleSticks96]

4.0.7 beta, all DLC/Season Pass, Year 2325, Galaxy Size 1000. It is mid game but I am experiencing end-game lag. To be fair, both the Khan and the Voidworm crisis are happening at the same time, so some slowdown is to be expected from all the AI fleet movements, but I never got slowdown like this prior to 4.0.

 

[Sirbab]

Here's mine, but I don't know if this is specific to the new update or if my system just doesn't run Stellaris well. It seems to hitch every half second or so if I'm moving my camera around which is very bothersome to look at. And this happens even if paused bizarrely enough.
If it's helpful:
My system is the following:
CPU: i7-11700k 3.60 GHZ 12 thread.
GPU: RTX-4090
Ram: 32 GB ddr4 ram (At low frequency due to mobo issues.)

Edit: For what it's worth, I posted my issue to tech support as well.

Getting unbearable lag at game start in patch 4.0.6. The save is not even a year into the game and the lag is somehow worse then end game lag.
1,000 Star Galaxy
10 Empires
0 Advance Empires
6 Fallen empires
Grand Admiral with scaling set to late game.

I made a bug report but since i wanted to make sure it was seen imma repost it here. My save started stuttering massively after reaching crisis level 5 for behemoth fury. It started on 4.0.7 beta last night and is still ongoing on 4.0.8. The beta was working fine over the weekend while i was progressing through levels 1-4 but yesterday once i reached lvl 5 is started stuttering and hitching. Also of note here is the immovable bio juggernaut although i can move it with jump drives and the bugged vivarium after rebuilding my destroyed grand archive.

Hello everyone!

We are currently working to track down the underlying causes of the performance issues, and we can use some help gathering more instances of particularly poor performance.

It would be helpful to get a variety of saves from (unmodded) games that were started after 4.0.3 was released, where performance is really bad. We'd like to use them for both script profiling purposes and to try to identify common elements between them.

Thank you!

Yeah this feels at least somewhat slow for an early game compared to a 3.14 equivalent. Could just be me, but I figured I'd post here anyways

 

[Chaosboy]

I have a kinda slow save with some strange pop growth.

From the 1st save:
