Hi Kafka. I realized a while later what you meant by environment. I'm old and slow. I'm using the GWX 16k atmosphere. I started using it just recently and would not go back now. So much better I think, especially the clouds and the sun.
Funny, I never realized there was that much rust on the stock skin, but I haven't used one in a long time. There are so many good mod skins available it's hard to decide. There's still a lot I'd like to try.
Thanks again for the comments, it's very encouraging.
