Strange FPS drops (10-1 FPS)

I have a save from the user @.ggtk [discord] here about strange FPS spikes in this save. I could reproduce it on my machine as well (9800x3d).

I ran some test on it but couldnt find where the spikes are coming from (but since i dont move the camera) this spike are still occure it is something in the background. Might be worth taking a look at it. The picture are from my factory and this and mine is end game already and the FPS are cap at 45 (30 in the background). The FPS are dropping down to between 15-1 FPS but just for a split second until they go back up to cap limit again.

The save is vanilla so there are no mods involved in this.

I have a 9955HX3D laptop processor, which should be plenty. But similar CPU architecture, doubt it's the problem though

I can confirm the autosave interruption is much shorter and causes less slowness on my system

Game speed?

Ran at 12x for a while and didn't see any spike, do you have an exact date\camera position of when it happens?

Ok found the reason and i feel stupid the lags cause if try to pick up building from the building list. I run the game one 1x speed before i took the picture you see the lag spike there. Not all buildings cause a spike

spikes are cause by gas injector pump and Kiln (gas) and mixer II (there are more but i just named 3 of them). But this bug will only happend one time after that the spike will not reoccur again on the same building (as long you dont close the game). Seem like a loading thing

So not sure if that worth fixing, strange is that it only happend to spefic buildings. Not all display this behavoir. I tested on my save and got the same spikes here:

this is how it looks normal when i play and move the camera around the map and doing stuff. Cap at 45 FPS as i set it to be.

I played a fair bit today, my FPS spikes have been random and not really related to the building picker, as far as I can tell.

I haven't played over the week, but the spike is strange today. It's regular, hitting exactly every four seconds, I'm guessing it could be some item on a belt spawning in every four seconds for example

Ive been wondering if some sort of performance tracker mod could help pinpoint the lag spikes through call & function read logging

i dont think there is however im pretty sure the dev can track it the problem is there need a system that reproduce them.

I've been running on 1x, 20x game speed, selecting items , zipping around camera, having no major lag spikes on high performance, english version . I'll keep playing this world for fun
