Hello friends!
I am experiencing some problems with very large scenery in 3dgs!.

Could tell me what technique I use to optimize the process of very large scenes in 3dgs?

Let me give an example of my problem:

I created an extremely large world, divided into towns, plains and more.
There are plenty of trees, rocks, mountains and various objects in the world.

Taken together with the final visual effects, my world becomes unplayable.
I can not move properly.
Very Very Lag


Please! Use easy words to be translated. because my English is not very good! Grateful.
