After more testing, I've found that it is not as apparent with using only deadband as I suggested using. When using only deadband to test it, it does move offset, but since the stick never returns to true center this is almost impossible to notice when in the cockpit visually.

So if anyone could please try the following method and I would be very happy:

1. Set sensitivity of your roll and pitch in IL-2 to zero for the three leftmost ones, and set deadband to zero for both.

2. Step into the cockpit ON THE GROUND (do not be airborne since it is harder to verify) and zoom in on the control column/stick.

3. Move your joystick very carefully across it's center point, as if barely moving from center at all. What I see is that the column moves slightly to the left (just a bit) and slightly forward whenever the joystick is at true center. When moving away from it, the (cockpit) control column returns to true center.

If you have any external software to change the curves of your stick, set it to lowest sensitivity, as that will make it much easier to hit the centermost positions of the stick.

I just tried this with my Saitek Quadrant with nothing Logitech control-wise connected and the virtual driver bus interface disabled in the system settings even, and I observed the above.

I find it very unlikely that IL-2 would be any different on my computer compared to others', and it cannot be a hardware problem since it is only brought on by trying to use the IL-2 curves (Sensitivity) native to that application. The bug itself appears when a control input is at true center, which implies that there could be a coding mistake where the curve sensitivity processing is turned off if the controller is centered, as 'there is no need for it', and it re-engages as soon as the controller leaves center. But for some reason what is considered 'center' for the processed input is slightly offset, perhaps the exact same distance that is required for the controller to move before the curve processing is re-enabled again.
