I noticed that my joystick controls, esp the rudder, are very bouncy when I log in sometimes. Every time that happens, I log out and log back in again and the problem is solved. I calibrate before I log in the first time, and also calibrate in game when I log in each time.
So, if my controls feel lose, I just relog and they're fine. Don't understand why that happens or if there is a way to prevent the lose feel to the joystick some other way. I have a LogicTech Extreme 3D Pro. If others have the problem, try relogging.
