MY FPS takes an extreme dive in battles. I never get this in the actual Rome 2 game or in any other mods including Constantine. I'm even sometimes getting stuttering like you do in siege battles with just 5 vs 5 units, except the stuttering is happening in an open field battle with just grass and about 2 trees.
I've lowered everything that can be a CPU burden and it's still barely playable.

What's been added that can cause such huge slowdowns?
