Before the soldiers reach to the gate or stairs placed, everything is fine no fps drops. but when the period they starts to engage with enemy with melee, or after the first gate down with ram, my fps just goes ground zero, all freezing and everything.. Probably AI path issue. its doesnt fix until the end of the battle. literally until the last defencer goes down, everything is freezing. I dont have any fps dropping issues in any part of the game but siege battles.
The interesting part is everything was fine until few patches before. like 20 days before or something. Might be the patch after when they fixed some ladder issues but not sure. Also i dont have any mod that effects siege battles or ai pathfinding.
edit: I know the problem probably can't be hotfixed with 20mb update might be bigger than that but i would like to see focused on because sieges are huge part of the game as everyone can agree.
