For FPS games such as a WW2 i hear you might be using the engine for, i think the drawing distance is crucial importance. Maybe if you played Operation Flashpoint you know. And if you 'zoom in' with binoculars and stuff you have to solve that too, how trees convert from low to high poly count if you zoom into them from distance. It takes a bit of effort to make it real good.
