nothing has fixed with 1.5.5 open beta version. Still need to use vjoy for F15 aircraft. I tried to clean install Windows 7, Windows 10 joystick cobra m5, Saitek Cyborg X, Logitech Extreme 3D Pro, pedals "Hall sensor + Arduino Leonardo".I also tried to set the DCS on the rudder dead zones at 90%, and sought to move the pedals still 50% = drop fps.
On the plane F15, you can set a total of 22 axis. Fps drop 15 axis.
