Good evening, the dcs integrity check has passed. Windows SFC didn't find any issue for integrity neither. I was able to bring the joystick virtual center back to center, by using hardware trim, and I disabled the hardware trim then launched the dcs, the virtual center stays at center of the grid and never moves. I found that the Center value for the joystick stays at 0 all the time, while Coefficient changes from 4055 to 41, upon pressing the trim release in dcs. The center value for the Pedal is showing position value and changes as I move the rudder, so I assume the joystick value is somehow not getting to the application, despite I can move in-game joystick by moving the physical joystick. I see the issue is the same across multiple helicopters I tried, Mi-8, Mi-24, Ka-50III and AH-64. I double checked the vjoy is disabled and restarted and checked again. I'm trying to see where the problem is. May be the dcs is not generating some part of FFB command. I checked the dcs.log again, so far I don't see any errors regarding the FFB. I flew Yak-52 and F-4E, the dcs generated effect doesn't seem to be applying to the joystick. Any ideas where to check?
