I claim nothing. It was posted repeatedly, that the current maps seen in the screenshots are merely placeholders and testmaps for various settings and the original SoW map will not be shown until the engine enters beta. The houses and ground-objects are placeholders, as well as the textures.
Infact the shot from the map you posted earlier even came with the comment, that the odd-looking hill was just testing the map-builder.
Nothing miraculous about it - just look it up.
@ AdMan:
Who said atmospheric haze is unrealistic?
It was just said that a dark brown haze on a sunny day at high noon with 1/8 clouding is unrealistic and yes, indeed it is.
