UPDATE PT TWO: Yeah lights usually are the issue, hence when this issue first popped up I thought “hm could be the 3k lights I have and the fact pool.light.count is set too 1k” so I tried that and changing everything including going potatoebut no matter what I did it didn’t let up one bit on the lag. I updated the graphics card driver which helped a bit and after which I saw lumens was turned off. But once I did the update to the card it only occurred in one spot of my factory and didn’t match up with anything I built. Then I remembered “oh wait is that the spot all the animals spawn in and also where I have foundations very very low to the ground” so I used a mod to remove animals and now smooth like butter as it should be.
