Im having a lot of lag also. I have low graphics, frozen animations, no effects, fast combat, low textures terrain, etc etc, and every little thing i click takes a couple seconds to activate; VERY boring! You want to activate one unit inside a stack, 1 second; i click fortify, half second; shift selection, 2 seconds per unit picked; etc. To open a city screen is even worst, several seconds. Between turns i read one paragraph of a book i have here. Im thinking about removing global view and unit/ambience/interface sounds, but i dont think those are cause of lag. Damn! I used to play huge maps! Those slow dows i listed in this post were found in a DUEL map with 1 AI, that i started to check the new warlords features; Ill never be able to play a Terra map again, it seems...
