Hello I'm having a recurring problem, other people are having the same problem. My aircraft float like drunks, impossible to fly, especially helicopters approaching buildings, ships and the ground. even with the adjustment of curves, it is impossible for me to land or take off. Compared to others where the stability of the devices is perfect. Some evoke the joystick, or the problem comes from the network, others speak of FPS, others evoke weak graphics cards. My driving respects all the rules imposed on the conduct of aircraft. My config: Graphics card 2 Gigas overclocker x 4 RAM PC 32 Gigas Processor I7. 3.5 Windows 7 Pro system. My questions are simple: Have you encountered this kind of problem, do you think it comes from deaths, how can this problem be solved definitively?
