Hello all..
I downloaded the city prefab on the acknex resource site, the very BIG one.You know how big it is.Anyway, I want to put it in my game, so i loaded the prefab, made a player and put a player action to it. I built the level ( for a long time, but i think its ok 'cause its such a big level).. So i ran it, took a long time to load,then alas, it opened...what looked like a slideshow! the framefate was ridiculous, it only increases when i look at the floor or some small areas. I have seen a tutorial on how to handle big levels, know any?

Pls give some tips so i can run my game, tnx people!!
