Theres a fallujah map in the works, was posted in the DEV journal but is gone now. Don't worry mate, we're all seeing some lagginess on fools road and quinling. Part of it is certainly there size, but I'm sure there is also some optimization that can be done as well. Future releases may help quite a bit.
I love the map size, it's the lag caused by air vehicles that annoys me.
Btw, QinLing is the most beautiful map you guys have produced yet... I LOVE assaulting Coal Mine, sometimes I'm too besotted by the lovely pastel landscape and I get sniped.
I dont think no one gets why the maps are so big. Its due to the NEW planes, sight, armor, and other new things. Along with the reality aspect of this mod. BUt to stop lag I must ask this question. How much RAM do you have?
you've answered your question with your own post :/
Smeg: Fuzz commands a lot and promotes good teamwork, db flips vehicles, Bosco is an all-round nub, Outlawz is an SP whore, Nickbond is a friggin ninja and Rhino gets kicked for being a n00b.
