Naval battles slow game down considerably

[MoldyOne]

for some reason whenever there is a naval battle, the game slows down to a absolute crawl, like speed 5 is slower then speed 1 slow down. it feels like the slow down that happens when the soviets go into civil war and it populates so many units that start fighting. is this something on my end or is it a problem with the latest update?

I have all the 3d options and texture set to low, i am running a i5 3570k with a Nvidia 1660, all the latest updates and drivers (first thing i checked) and this only started with the newest DLC

i wanted to add that if no naval battles are going on, the games runs fine with no issues

That's weird. I have not experienced that.
