I'm guessing there must have been an update to the game that busted it because I am only now having this happen. The game is actually un-playable as it stands and the FPS drops happen at any given point in the game. Not just combat.
I would love to finish this game but as it stands I'm going to have to take a break and pray that an update rectifies the issue.
