If i attack a well developed town (where you can see the town during combat) the animations are really choppy now.
Hovering with the mouse over an unit and quickly moving the mouse pointer to a nearby unit and back repeatedly very fast stops nearly all animations from every troop.
I have a save here, just before attacking a town if that helps you.

Note: i think this got introduced with the .990 Version, it was fine before.
