Customer Testimonials

Gary Watson

I simply cannot say enough good things about your software. The only thing better is the fantastic customer support!

Grant Savage

This is must have software for flight simulator and truly enhances the realism. It also has an incredible well programmed weather engine that makes weather transitions silky smooth. The number of options that REX offers is outstanding and there are thousands of options to choose from.

Donovan Warren

REX adds the extra realism that hardcore simmers demand. I couldn't believe how real the clouds and skies looked, as well as the runways and water. It's a very nice addition to the flight simulator and easy to create your own environment.

Simon Schrooder

A must have for every serious computer pilot. The most fun I have ever had with the simulator is with this add-on.

Christian Duncan

REX has transformed my flight simulator experience. The incredible realism of the cloud formations and water effects have to be seen to believe. I particulary like the tropical "haze" effect towards the horizon when flying out of my old favourite location of St. Maarten in the Netherlands Antilles. In 25 years of flight simming, REX is probably the best add on I have purchased.

Gregorio McKoy

Sit back and enjoy!!! The graphics will blow your mind. It's like purchasing a new flight sim. I found myself just aimlessly flying at all times of the day in awe. Wow! Great job developers.

Alaa Riad

I have been viewing so many shots on the net from people publishing their REX work, was very impressed but hesitant. I finally had the guts to move on and purchase... then magic began! It is simply unbelievable and a real step ahead in graphics and capabilities. Now you can design your world. To me it is like a dream come true.

Andrew Myles

All I have to say is WOW!.... go buy this. It will transform your sim flying forever.

Woon-Kyung Seo

I have purchased a number of graphics enhancements for flight simulation over the years, and most make an improvement. However, REX almost totally remakes the simulator into something new. Seeing a realistic sky for the first time in all my years of flight simming blew me away. The first thing I noticed was how nice it was to see the clouds reaching all of the way to the horizon. There are also no more of those constant redraws of the clouds. I give REX 5 stars, 2 thumbs up and a laurel and hearty handshake.

Kai Prout

Well I am going to keep this short, sweet, and simple. THIS IS BY FAR THE BEST THING YOU COULD EVER DO TO YOUR FLIGHTSIM...

Patrick Smith

What can you say about this masterpiece of software engineering! The developers have made giant leaps forward in providing an immersive experience within the sim. Well done to Tim Fuchs and company! Just to recap, simply excellent! I just wait with baited breath as to what the future of this software will hold. Mega thanks and awesome recognition to all involved!

Craig Muncaster

One word, amazing. Took off from RAF Lossiemouth in Scotland in FA/18 hornet in early morning sunrise. Everything set at max resolution set to 6028 x 1080 (for bezel correction). Result stunning before I even get to the sky the water looked like water but full afterburners on into cloud layer then breaking through to sunlight just stunning still got over 50 fps. This takes the sim to next level.

Gary Johnson

Everybody involved in REX are the best of the best. No exceptions. Nothing will prepare you for the awesome change that REX performs to the sim. This is the best there is. If you have not bought this yet, you're really blowing it big time. Just get it!

William Vick

REX has truly has changed my flight sim experience. It would take me too long to describe all the things this program improves but let me say the clouds and water effects are amazing.

Lester Hesley

This piece of software is a must if you want stunning visuals while flying day or night. It will bring a NEW dimension to flight sim and you will not believe it until you take off and see the 3D clouds, sunsets and the water effects on inland waters and ocean corral.
