Flying high spying my land

I like to disable the fog when I’m trying to render things a bit quicker. Usually, I can’t see the land below my feet when I’m at high altitudes. I just noticed today that I can in fact see the land below me feet. Other objects between myself and the land do not show up. This makes for some really great LOD issues with machinima. At the moment, I am 930 meters high in the sky with a draw rate of 64meters. Of course, this is windlight. I don’t know how this works with the current build or release candidates. Turning fag on hides the land due to the distance.
