I’m also interested in this, been flying in South America quite a lot until a couple of months ago and a better mesh is welcome.
However I’m on the fence. I mean, plenty of screenshots but no comparison between, say, Torres del Paine in MSFS (basically the visual representation of sadness) and the new mesh. I would think a comparison of the area before and after would make the sale of this an easy one and the fact that it is not there does not inspire much confidence.
If anyone happens to fly there with the new mesh I’d be grateful if they could grab a screenshot and post it here.
