I really like the last two. Is that the default 747? And are you using the shockwave 3D lights? Looks really good.

DX10 is better for performance, atmosphere and light deep but somehow reduces reflecting light on objects, and on the other hand I get artefacts on water surface with every 174.xx driver on my System.
