Trees do use some LOD. But also depends if you have F9 on or off.
Layers could help. It will calc the whole scene, although for final render it's only the camera frustum that's used. Certainly for something like lights it is definitely useful to have in layers and turn off.
If you definitely know some geometry is not in or going to be within the camera view then placing in a layer so hidden would affect render time, but by how much I don't know. Probably not that much, things like drawcalls from having too many little textures have more impact, but if the object is complex with lots of texturing then it may be worth exploring us of layer (if you have enough, max 20).
Are you still getting the white?
I'm running the newest GTX 680TI gpu,..
? 680Ti or 780Ti?
