If i but 500 Soldiers on one end of the map and the player on the other side. The fps drop is very high. But why do i need to calculate them if i cant see them? Calculation of AI should be bound to view distance or Object visibility. Just calculating the way points and time to get there. But not how to get there, if the out of view.
I hope you understand what i mean. My English is not the best.
I think that could be a major performance boost. If it´s possible.
