i've noticed that there is not a button to toogle shadows on/off in the video screen. i'm not a programing scientific, but i think that due to the high concentration of trees and another objects that create shadows with the light is dropping huge amount of fps in low end pc's like mine. i was searching for them because is the first thing i toogle off when my pc is droppinf fps in a game.
suggestion: allow us to toogle on/off shadow settings
