Thank you, Grinde81. Just as I thought, its the games fault.
I tried other airplanes and even in the small ones there is the same delay, actually. I was wrong above. The fastest reacting one is the small stunt plane. All others have a huge delay.
If you go from left right and again a few times, really fast, no matter the plane, the joystick in game barely reacts.
This by no means is an accurate simulator, where you cant even properly control the planes you’re flying.
So I give up on this and hoping they fix it some day, if ever. Till then, this remains a sightseeing game, no more.
Xplane11 is so much better in terms of flight dynamics.
