Remember after the terrain update, when all the terrain totally blended into itself? You could make out no shapes, bumps, nothing, until they broke the horizon (secones before flipping you over or killing you)?
Well that was fixed eventually, but only just barely.
I have a feeling that once the new terrain is finished, and we have better quality lighting and textures to fly OVER, that planes will stand out better (as they should) against the ground.
It's like the terrain is over-saturated or something. I've had a harder time seeing green icons against the super-blue skies since AH2 came out (as compared to AH1).
Definitely improved in some places over the older game, but leaves room for still more improvement.
