Preliminary report from me too,
Gap:
I agree with
tonschk that the sky isn't as blue as with Real Env, but I can certainly see a difference, and a much welcome one too.
Example, leaving Kiel:
Yes, it's a pretty awesome shot too. I just got myself a new desktop background
On a more serious note, compared to what I used to see, that's much better. The blue is "bluer", so to speak. Not a deep, Mediterranean blue, but that's really not all that common on those latitudes anyway. The "problem" with the old color settings wasn't that there wasn't any blue in them at all, I could see that there was blue hiding behind all of the white/gray, it was, in my humble opinion, that there was too much white mixed in with them. With the new ones, not so much.
I can now actually tell the difference between clear skies and hazy, foggy ones
Also, what may have helped a bit here is that I did a full reinstall and restart because
Trev, once again, decided to update his awesome OHII, which is what keeps me from ever getting past 1940 (I kid, I kid

) and, since I was having odd artifacts that I'd never seen before too, I decided to just start over again. This has also made everything run smoother and the artifacts (such as the ocean "resetting" every 30 seconds or so) have disappeared as well.
But I've done a lot of restarts before and they never changed the white/gray skies from DynEnv, so I know for a fact that your changes did something wonderful as well
If I have to whine about anything, it would be the disappearance of the green North Sea waters, but that's really not that much of an issue at this point. I just enjoy being able to see the sky look like actual sky in between the occasional cloud.
Sorry I haven't tested the Arctic, but I'm sure that somebody will.
Thanks,
Gap, and keep up the excellent work!
