There was an FS9 post about clouds recently that mentioned ASN.
I'd downloaded a time limited version of ASN a year or two ago to help decide between Active Sky Next and OpusFSX.
OpusFSX won.
But many strongly prefer ASN, so I thought that I'd try it again.
Same thing this time - Opus won again. But that's a personal choice, and this isn't a discussion about which weather engine is better.
This just a few pictures about what happens when you run BOTH of them together, at the same time.
Strangely, nothing crashed. This was with Prepar3d. I didn't try FSX.
Of course lot will depend on just what the weather is at the location that you're flying in.
Just for the record: This is BOTH programs running together. It looks very different with only one or the other running.
I need to save money, not to buy software, but with ASN on a sale that ends Friday, it is tempting.
