c# - Gamepad thumbsticks active range -

for current project use gamepad. successfull in hooking in c# through slimdx. works fine, problem thumbsticks don't use active range.

if move stick way left on x axis, maximum value half-way through. driver clips values returned.

i understand, why happens. driver operates in square area, stick in circle.

the red circle marks values driver. blue area represents actuall physical range of sticks , green 1 want gamepad. these readings in calibration utility , in program too.

my question is: normal behaviour gamepads? have buy better one? i'm using cheap 1 - genius maxfire grandias 12, don't want invest this.

as turned out. genius maxfire grandias 12 gamepad not one. have tried different model, , working expected.
