Insane FPS drop when fighting Eve's automata made snake in 1080p

Hi, i've been using the mod for a while and it works perfect, even got a huge improvement in the latest versions, but when i get to fight Eve at the end of the first ending with the flying cerpent made of lots of automatas i get an insanely fps drop, but the wierd part is it only occurs at 1080p when i drop the resolution a bit it then runs super smooth again, (the fps drop is only there for the rest of the game it runs smooth at 1080p).
