Wow. Here we have a great program: Skymaxx Pro 1.1 - and many are wishing for 'even more' features. I have to say it- just getting rid of the grey wall of death was worth every penny of Skymaxx cost. The beautiful clouds are simply a bonus! I am not in love with REX. I used to fly FSX, and even with Rex Essential HD OD, the clouds were not 'all that' and a bag of Tostitos. IMHO, they looked kinda wrong where the clouds intersected the mountains. Nothing is perfect, but I am firmly in the 'happy camper' category with Skymaxx Pro.
