Getting decent performance at around 35-45 FPS with my 980ti, i7 9700k and 16gb ram, this is at 1440p at high settings.
I'm a complete novice to flight games, and I've only really done a quick few flights for a few minutes, hut is there like an easy A-B mode where I can follow waypoints and the game tells me when to descend and the right altitude for landing etc?
Go to settings > assistance and you can turn these sorts of things on
