If it's a choice, get ActiveSky (AS) first. The single greatest thing
about it is that you can SEE weather sims in the distance and fly into
or around them. Compare the default weather, where you find out there's
weather ahead only when you fly into it and suddenly you're in a
I purchased AS when the new version came out this spring and was very
pleased. Recently, I also bought Flight Environment (FE); this too
exceeded my expectations. There are other sources for beautiful clouds
-- and if you buy ActiveSky V, it comes with a bunch of cloud sets that
are actually integrated with the weather generator. I have been
happier, though, with the FE clouds. Your mileage may vary! But more
than one person has reported improved framerates with the FE cloudsets.
See http://tinyurl.com/8uys3 for the author's explanation of how this
is possible. What happened in my case was slightly different: my detail
went up (from 64x64 to 256x256) and my framerates stayed the same. The
result was much better images without loss of performance. I repeat:
your mileage may vary. But I am very happy. And FE comes with great
water textures, too.
Bottom line: the combination of AS and FE adds a lot to VFR flying.
