i was experiencing extremely low frame rates in this map (2-4 fps), i first thought it was because of my low end pc, but i discovered that it only drops when i look towards a certain building, this one to be exact:

after further inspection it seems that the ammo props in this room are the cause of the low frame rates:

after removing all the props in this room the game ran in 60 fps no issue, is there a possible fix for this? why are these props causing such low framerates? and how can i fix it?
