Just simply "polish up that part of the entire planet" when they're busy updating entire continents? I think they have their priorities in-line.
You want the devs to to a bullshot trailer by removing imperfections that exist in the actual product just to make the trailer?
I wish every dev actually showed their games the way they'll look at launch. How many games in the last decade have released with everything from missing shadows, to shittier textures, to heavily reduced geometry? You keep shitting on it for some reason and claim it's never going to be fixed, but the software is a flight sim, it's not a normal video game. Sims are constantly updated over time. MFS has already had two massive map updates, one of which greatly improved an entire country with new elevation data and a lot more photogrammetric data. MFS will absolutely continue to evolve as time goes on.
That would be a feat, in major centers like New York on even a beefy PC this simulator gets pretty heavy and starts to chug.
The game's performance depends on your connection too, an unstable connection can cause some severe performance drops. I have a 600+Mbps connection but at launch there was a lot of work being done in my area so our internet was cutting in and out and speeds hopping around. The sim became unplayable during that time, otherwise with a solid connection my frame-rates and how the game looked was consistently impressive.
