Probably something you have all expirienced.. in the mid to end-game stage of 100 and 500 maps the game starts to slow down and lagg A LOT. Also coalition members are complaining about this, over different games. I really like this game and the strategy involved, however this is more and more leaning towards me quitting, its just not worth the frustration that the lagg causes.
Now from what I hear there is also 'legacy mode' and this doesnt have the same issues because of very basic graphics?! Would be great if this becomes availible to everyone.. so I can switch to that in a stage of the game where I start getting issues.
Or ofcourse, solve the issues.
