For the moment my city in not very big. 300x150 mÄtre. I dont have the number of object because i only work on the mission editor. Its very long and hard, but i havent got any other choice because i dont know how to make island with others editors...
I m a french noobs...
Its a small island, so the frame rate is very high. For the moment at 50 % of the final release, the island is very playable. It just take 1 second to charge the island from the editor !
