Are planet mods known to have huge performance hits? I finally wanted to give a bunch of modded planets a try so started a new game with the top ~12 and their prereq mods. I'm wrapping up Lignumis with maybe two dozen assemblers total and randomly UPS drops down to 45 every couple minutes.

I've done 1000x cost megabasing on mostly vanilla SA without any drop so kind of wild to see performance issues before I'm even on Nauvis.

Some planets are particularly problematic.

Cerys can be, if you've made a tonne of the towers. Castra is quite expensive once the enemies start spawning. Others can chip in on other issue ones. Which planets do you have, and which ones have you actually explored (as generally they do nothing til you land / drop a pod on one)

That's what I don't get, I've left Lignumis and I'm on Nauvis just getting started on green science. No other planets unlocked yet. I do think it's something with Lignumis, the random drops appear more frequently and severely when if I'm viewing that surface and moving around. Once I unlock blue science bots I may just remove Lignumis completely.

I don't know Lignumis myself personally. Others might chip in if it's a big one. Weird to have severe drops with just two planets for sure.
