First of all: I am a meteorologist, and I love MSFS2020 and I will most probably love MSFS2024. I think everyone of us has his/her own certain aspects of the sim that we are paying most of our attention to. For me, personally, it is (not very surprising) the weather. How it looks, how it feels, how it is simulated and how realistic it is. Let's make one thing very clear, and I think no one can honestly deny that: MSFS2020 brought the weather depiction within a flight sim to a whole new level that no other sim could deliver so far. That alone was a huge accomplishment and a huge leap forward.
But: There are some aspects of the weather system in MSFS2020 that drive me crazy sometimes. Especially because from what I can tell, these aspects are NOT due to some technical limitations of some platform or because it is a too complicated thing to simulate properly. It might be because of other things having more priority, I don't know. And I have to agree with the OP that there is some evidence in the trailers that at least some of these things might not significantly change in MSFS2024.
These things include:
- Lack of variety in cloud types, especially high altitude and cirrus clouds. The current cloud engine is simply not made for some cloud types. Cirrus clouds can often dominate the look and feel of the sky. This aspect is completely missing in MSFS2020
- Clouds are way too transparent, especially in live weather, and clout type variety and depiction of towering cumulus es even much worse than in the presets. Towering cumulus and thunderstorms are pretty bad in live weather, much too shallow, and precipitation and sometimes even lightning visible beneath what everyone of us would normally call a fair-weather cloud.
- Visibility far to high in most areas, especially where no METAR is present.
I completely understand that at least some of this might not be important or even relevant to others, for me it is, and especially the quality problems in live weather drive me crazy. First of all because I almost always use live weather, and the sim proves that in can do better if you play around with the presets or use some add ons.
Conclusion: Let's wait what MSFS2024 will bring on the table and then we can judge 🙂 I am really looking forward to that release, what ever the weather system will look like by then.
