Campaign/battle map suddenly unplayable due to lag

[Aodh Mór Ó Néill]

The game was running fine, and now for some reason it lags to the point where the game is unplayable. I didn't change the game in any aspect prior to the lag starting. Even with the settings turned all the way down its impossible to play.

This ever happen to anyone else?

This happened to me before in a Parthian campaign. If I had to guess, there is an infinite while-loop in the campaign script running nonstop. What happened right before this lag began?

Nothing, I hadn't played in a few days, I came back and it was suddenly lag city.

It's happening on all new campaigns/battles as well.

I'm afraid I have no other ideas other than restarting your PC/laptop. I'm guessing that a rogue process began hogging all your CPU at some recent time. Try opening up your OS's process monitor and seeing if something is eating up CPU or energy.
