@Orffen:
The curve is how sensitive the joystick is across the range of motion. Take a look at this image for an example.
The saturation is where the “maximum” of the joystick is. For example, if your X52 doesn’t give you full motion when you’ve moved it the entire way down an axis, you’ll want to setup some saturation so it thinks full motion is less than 100% movement.
For your use case, I’d suggest setting pitch and roll exponential curves. Maybe start at 25 and work up/down from there.
Actually, X52 Pro doesn’t really need pitch/roll curves, linear is good enough to emulate F-16’s force sensing stick. Yaw is another story, when using the twist axis you might need like 40 to make it controllable. Same with TDC if the hack is used to make the ministick mappable - 50 is the minimum here, since those are like 16x16, afaik they’re literally DS2 dpads.
