"When P3D first brought / introduced us to dynamic clouds, I was instantly grieved. Now that it has been achieved for FSX thru/by REX, I've been rolling cumulus-ly with amazement!!! You will not be disappointed ...not one iota of gleam will escape your very next flight in FSX. Thank you REX and continue to bring on the Realism...Wooooww!!! All I can say is that I'm fully enjoying this...What are you doing?" - Keino Furbert-Jacobs

"REX I have to say have a record of consistently offering us manuals at a very high level of detail, offering us clear and easy to follow instructions. I immediately noted the improvement to the 'look' of the clouds, i.e., a more realistic presence. During my many flights I experienced some excellent ground fog effects, and cloud layers I flew through had a real 'fluffy' feel. As you fly through various cloud conditions you will begin to notice the softening of the clouds/effects you had not seen before. For me, this has proved to be one of the best purchases I have made thus far, and the effects, well I think I have covered that in the above...One word: Incredible! REX enhancements really do make a massive difference in the FSX (and other platforms as stated) environment and here is the major point, REX have ensured, that if you have a top-end or towards the bottom end of performance computer, you will still see a marked difference in the cloud environment. Now that is truly amazing, and REX rightly deserves a positive virtual 'thumbs-up' for this broad compatibility. In my experience REX enhancements have not had any diverse negative frame rate reduction hits, such is the quality of the products I possess on my computer, Soft Clouds, no frame hit just massively enhanced clouds effects. Two words: A MUST!" - Nigel C. Martin

"From what I notice this looks great! Was exactly what i saw when looking out my office window. On the climb it is nice to see a variant of soft clouds in the mix." - Thomas Riley

"What I am seeing is a a beautiful balance between soft and the HD famous REX clouds, they look great and feel more real than than anything I have tried. I wont have to keep looking for cloudscapes now." - Rich Sennett

"Bottomline. If you want the best soft type clouds for your flightsim, then look no further than REX Soft Clouds. These will blow your mind how real they look, especially when flying through them. There just isn't anything better, period!" - James Holcomb

"I am a P3D v2.4 user and the smile on my face will take time to go away. These clouds hug mountains and hills like no other. What a brilliant addition to the REX cloud family." - Robert Pomerleau

"Well, this was a fantastic surprise...and for 10 bucks, was one too hard to resist. Installation went well... was instantly wowed just how much these add to the realism in flying through real clouds. A job well done guys! How could I ever doubt you anyhow!" - John Lovell

"Yes, I waited a long time for soft clouds. In the real world, not all clouds sharp. I am glad they are finally available." - Ales Kubovic

"For $10 USD, it's really hard to go wrong with anything REX puts out. I cannot comment on the P3D performance, but in FSX this is an excellent overhaul to default in a lightweight package. Very happy with it so far!" - James Hunyar

"I bought soft clouds and I am amazed!!!!!!!!!!!!! Simply stunning for such a small price it is well worth it!!!! Mist, fog low visibility settings are fantastic!! I fly VFR in real life, this is one fantastic product my friends. Complements the REX update superbly." - peetyrobo

"Now you can really fly through clouds and fog!" - Dirk Henke

"Just bought and installed this. I already had REX TD4 and was wondering if this product would be of any benefit - it is! The low / mid level clouds look amazing. Awesome add-on at a great price." - Murray Dreyer
