Im using a speedlink black widow sl 6640 & in previous edition of Flight simulator it used to vibrate with turbulence etc.
I’m not sure if the vibration of the joystick is broken or if it is simply because force feedback isnt supported in FS2020. I kind of miss it from previous edition of Flightsim.Been looking for an hour for driver fixes or some force feedback program.Had no clue what was wrong & never heard of force feedback… I’d love my joystick to vibrate again 
.my joystick is working fine for the rest. But it was immersive to feel the vibration with turbulence etc It was a nice extra flight stimulator
