The implementation of the cloud system in Flight Simulator 2004 introduced a new way to display cloud ‘sprites’ which simulated 3D clouds. This system is still in use within FSX, FSX:Steam and Prepar3D. With the current cloud model system there are many limitations in regards to the way clouds and full weather systems are properly displayed. For example:
- All of the current cloud models utilize randomly placed sprites. These sprites are randomly rendered inside the simulation, causing most cloud types to be mis-represented within all weather scenarios. This also severely decreases frame rates because of this unnecessary cloud sprite system.
- According to real-world cloud specifications, cloud thickness is lacking on all cloud types, including position and overall representation. You periodically notice upside down clouds and inaccurate cloud formations.
- Overcast is not truly represented and containing open areas, or holes.
- Limited thunderstorm representation and no true severity level as well as no precipitation visuals such as rain shafts.
- 5/8, 6/8 and 7/8 conditions are misrepresented.
- Limited cloud type representation.
- No ability to add certain cloud classification, such as rain shaft, wall clouds, shelf clouds etc.
