Yes rounded mountains and edges is one of the big problems of FS mesh. But there is hope :
- you don’t necessarily have to wait for an update to get better looking mountains : accurate mesh is part of the online data, and there are places in the world which already dramatically improved (without dedicated update)
Mountains definitely looking better (Pokhara - Jomsom Nepal) - Flying / World Discovery - Microsoft Flight Simulator Forums - the problem is acknowledged in the roadmap and planned to be solved in 2021… Wait and see.
