So I am not particularly adverse some long processing times if the AI is benefiting from it, but after turn 140, medium map, its going over 20 mins or so, and this is with me owning 45% of the map, a single minor, and 2 majors at war. Is this normal or am I encountering something odd?
In the one game I played super late (turn 300, woo) the beta patch cut my turn processing from ~25 minutes to about ~10 minutes. I highly recommend applying it. (no link because not allowed, but check the tech forum)
The AI turns get shorter, maybe, but your processing gets longer as your logistics increase in complexity; you'll probably find that if you try to use the preview logistics overlay there'll be a processing delay of at least one and possibly multiple minutes.
