"I am Loving it!"

I just want to congratulate and thank the folks at REX for creating such an awesome weather product, REX4 Weather Architect. Weather Architect has helped me create great IFR weather within the simulator. With this I can simply create ANY weather at ANY location, worldwide. The best part is that even though there was such dense cloud and fog depiction within the weather I created, the frame rates kept steady at 30 FPS in spite of flying the heavy jetliners like PMDG. I never saw this with any other product. The flight was smooth with no hiccups throughout the experience.

"Customer For Life."

It's rare that I write to a company directly, but I'm so impressed with Soft Clouds addition to my REX4 Texture Direct that I felt compelled to thank you personally. You clearly HIT IT OUT OF THE PARK! I have been a REX user since FS2004 and have never looked back. Superlatives come to mind, but fall short of what I just experienced flying from KNYL to KONT. It just has to be experienced to understand! Thank you and your team sincerely for your hard work, great contribution towards providing a very realistic experience, and the delivery of nothing short of an absolutely fantastic product!

"Improved quality, realism & variety."

Their realistic changes to the skies can make the world feel more alive than ever before. For any pilot looking to get the most realism possible to help benefit their training within a simulation environment this is for you. It will help make the skies both more challenging and more attractive to fly in, and means that when you do come into contact with your first real-world weather storm you will know roughly what to expect when it starts! Use for more realism and for a more comprehensive and engaging training program.
