I have tested X-Plane 12 in the last days and must criticize in some points:
- flash light in most of planes is too dark. It's not possible to see operation knobs
- heli R 22 is difficult to fly. No stabilize of the rear rotor!
- the clouds are not realy visible in wide distance, especially the most used cumulus clouds.
- I missed the tune of snowfall
In general, the weather menu is too complicated, much more than in XP11. You must be a meteorologist, to understand all the various possibilities.
