Optimization issues on endgame Savannah

So, I have close to 100 hours in this game and somehow, I havent played the Savannah map in waystone maps until now.

Well, Im glad I did, because my FPS dropped from my usual stable 60 fps to 45 fps(!)

Obviously this is an optimization issue tied to this specific map.
