Bad performance (Low FPS) with World Update 3 and new London photogrammetry - possible memory leaks

@Eefoe

is it that photogrammetry gets loaded into the session and never unloaded after you leave the area?

I guess it depends on the size of the area you are leaving. If the area is 100 sq miles, it will have a lot more photogrammetry than if the area is 2 sq miles.
