Citizens AI is managed by the CPU. In the endgame with 800+ villagers the CPU becomes a bottleneck…but I’m sure the devs still have some big gain optimization in the works…
i also hate the extreme LAG i get … im only on 220 pop … i have reduced my graphics down to as little as i can bare playing with… this is the part where i get so angry with the LAG i tend to stop playing the game for awhile… please sort out this issue devs FFS its grippling my enjoyment and clearly many others who play the game
