Did somebody do any tests how this affects turn speed? I play on huge maps, and the game I played before I installed this worked quite okayish in terms of turn speed. However in the current game I can tab out of the game and do some forum browsing in-between. Granted, I've installed a set of other mods as well for this one, so I can't directly relate it to this mod. Maybe someone has made similar observations (or not, both would be helpful).
another thing you'll notice is the game gets slower as the eras progress mostly because there are more cities and units for the ai to manage. Because this mod is better at making the ai settle and grow you may be experiencing lag because there are more cities earlier than your used to.
