• Review: REX SkyForce 3D

    There are two pages you can fill up with themes with 6 complete themes on each page meaning that you can have a total of 12 themes ready to be installed. If you want the details of each theme, you can just click the 'View' button and the details are displayed. You can also change the theme by clicking on the 3D clouds, the dawn, the moon or the sun/atmosphere, etc. and now you are able to customize that specific theme by selecting a new input and click the 'Add to Theme' button.

    In the general settings menu you can change all background specifics and they are all divided into various sections. These sections can be selected using the icons in the bottom of the screen and are grouped in four different groups.

    First group is the general settings which are the simulator platform and the path to it as well as backup configuration and various applications that can be enabled or disabled. You also here have your profile data, your settings on auto updates and notifications as well as your favorite airport list.

    The second group is the weather settings which covers the weather engine, the in-sim weather briefings, the specifics regarding Fahrenheit/Celsius, cloud sync, turbulence settings, icing settings, the rendering of clouds, haze effect together with volumetric fog effect, etc.

    Group number 3 is the textures settings covering which kind of textures and effect to enable, the resolutions of the textures divided on 3D clouds, cirro and moon textures. The 3D clouds and the moon textures goes up to 4096 x 4096 UHD settings where as the Cirro-Type is limited to 2048 x 2048 HD setting.

    Another great addition here is the Performance Risk Tuner with the Risk Assessment bar to provide the simmer with a very realistic and accurate idea of the OOM (out of memory) risk. This tool compares the settings you have selected to your computer's specification and calculates the OOM risk which is when the computer cannot support the simulators needs and thereby fails. E.g. with my computer's specs which are included in this review, and the lowest settings on the textures, the risk of a failure during flight is 13% - If I change the settings to be maxed out the new calculation states a risk of failure during flight of 27%. What this risk should be is of course up to you, but with a 27% risk of failure I still have only tried an OOM failure once and that was actually without the usage of the SkyForce.

    This SkyForce3D is absolutely a great addition to the flight simulation experience. The enhanced 3D clouds with a max resolution of 4096 x 4096, really provides the simmer with a sensational and very realistic visual experience. On medium computers the program is still a very powerful visual experience with the lower resolutions as 2048 x 2048 or even lower if necessary.

    The version that I tested was RexSkyForce_20180520_64bit / v.5.0.2018.0520 and the test was performed on P3D v4.1 and P3D v4.3. The SkyForce worked beautifully on both versions without any errors or failures.

    The interface is very user friendly and easy to navigate. Simple selectable options and the help function created for each feature pages in the program are just superb. I also very much like the Risk Assessment tool even though I normally am more a 'try-it anyway' kind of guy.

    I did encounter one issue which was the flickering visuals when using the max resolution settings in extremely detailed weather flying over a high resolution ground area with speeds of about Mach 1 or more, however that was easily fixed by decreasing the visuals to 2048 x 2048 instead. If your monitor is not able to visualize the 4K, then there is no need for selecting more than 2048 x 2048 in my opinion.

    Overall this is certainly a very powerful tool and an addition to the flight simulation experience that I absolutely will recommend to my fellow simmers. It is not just the awesome visuals that are greatly improved, but it is also the complete experience with the feeling of flying in different weather with various turbulence and the added sound of the rain and thunder, which by the way sounds completely awesome using my 7.1 surround sound setup.

    I rate the SkyForce3D for P3D v4+ with 4.80 out of 5 - this truly gave me an exceptional added flight simulation experience. Thank you REX Game Studios for creating this amazing addition for the flight simulation community - Keep up the excellent work!

      I purchased this when it first came out and could not be happier with it. You get the 32-bit and 64-bit version with it. It adds great realism with the new cloud models. When this is mixed with the new Weather force coming out you will no longer see weather updates that make clouds just suddenly disappear. They will gradually fade away just like real clouds as weather fronts change.

      The Rex Overdrive is not essential - I only use that when flying FSX and the SkyForce when flying P3D

      I was a bit dissapointed with SkyForce. It was an incredibly hype before release and it didn't work that well initially.
      Still waiting for "WeatherForce" that will eliminate these enoying transitions and will try it again then...

      Therefor I still use Active Sky where the transition is unnoticeable and I really appreciate the "Real-Time Texture Dynamics" option by them. No need to choose all these themes or cloudtypes. Just the current weather at my current location and this is where Actice Sky it great!
      It's a great weather addon (something X-plane really need).
