Hello,
recently I've been having huge frame freezes caused by massive UPS usage of most likely Laser turrets. It is most noticeable on the Space ship when destroying asteroids, and in much smaller size during regular biter attacks.

In here the average is 100-200 updates, which makes the Space ship unusable due to the flight taking 10x longer just because of UPS.
During biter attacks, the freeze lasts around 0,5 seconds, so its just little bit annoying.
It seems the issue occurs right after the last target the turrets can reach dies.
Is there a way to somehow remove this issue, other than avoiding these mechanics completely?
(gun turrets in space have the same issue, with very slightly better performance, haven't tested rocket defence systems yet)

Those don't look like normal laser turrets. No one can really answer your modded performance question without your mod list.

the mod list:




the turrets are the vanilla ones reskined by 5dim to red
heres the save file too https://limewire.com/d/zA22S#wltxM5rNKQ

Going entirely by vibes, my money would be on long range turrets or rampant.

The issue is completely removed when not using long range turrets... Thanks a lot. I really did not think something that small would cause so much lag.

My theory was that if turrets were scanning much larger than average areas for targets it'd add up pretty badly. How big of a range did you have them cranked up to?

I actually didnt tweak that mod at all, honestly didnt even know that i had it. It must have completely rewritten the way gun turrets acquired targets to something that was extremely update heavy.
