As in description: "Fallout 3 hit the shelves (...)" and nothing else matters :D
Well, nothing but Terragen :P
I've tried using fake stones shader for sand texture and it looks pretty well in the distance, a bit worse in close-ups thought.
And I've finally managed to make some nice billowy, smooth clouds without this whispy effect.
Used models by Ogre.

Clouds a little fluffier and I like it overall.
Hm, what do you mean exactly? More detailed, more billowy or bigger/higher?
Billowy. With some fluff...less dense.
