My sim does not solve LOD at all at the moment, and so far it remains pretty low on my todo list. There does not seem to be need for that.

DX11 lets you do on the card LOD and tesselation with geometry shaders...
There should never be a reason to download models to the card after game initialization unless maybe you're doing destructible geometry on the CPU.
