Hello guys, I'm having this problem when every time I get near a big smoke/dust thing, my fps will drop drastically

this is a huge issue for me because I fly trans, so every time I'm landing/taking off theres this dust effects making my fps drop, even worse when flying by the oil fields.
This fps drop seems to be more relevant in the standalone cause I remember that on the mod version I didnt have this kind of issue.
My settings are already on low and I was hoping for an internal tweak.
