I get very little difference in sensitivity no matter what i set it at. even when i go into my logitec program and turn the settings way down the stick is still way tooo sensitive to my movements. is ther something else i should be setting besides the dead zone and sensitivity.
Are you trying to use these test builds, or is this more of a general issue? If it's a general issue, thread split to support might be a good idea.
It's recommendable to keep the dead zone as small as possible. That increases the effective range of motion of the stick and thus increases the amount of control you have over the control inputs.
Also, with the retail I personally recommend keeping the sensitivity maxed as well. The control curve that the sensitivity setting adjusts is rather strange and unintuitive and makes the controls unresponsive in the middle with huge spikes at the ends of the motion range.
Then there's the matter of logitech's sticks generally being of rather low quality in general. What stick do you have, and what kind of axis response curve does it have, if you can observe it somewhere?
