Joystick lag

[FlyingPapy]

S!
I fly for a while on commercial sim and return to IL2 recently. I have a problem flying now, let's forget fighting, because the control surface lag. Roll, pitch and yaw are slow to respond to the input a give. I have a FF2 and CH ProPedal as input device. I have tried inside 1946 to change the input mapping, 0%, 30%, 100% with and without filtering, deadband, change mouse sensitivity.... nooop no luck. Any advises please, I want to return to combat.
