Head tracking stuttering - TrackIR low degrees resolution in game (INTEGER VALUE?)

[Monolith_17 0]

Hi i try modify all setting in MyNickName.dayz_preset_User.xml but the result is same.

I use TrackIR 5  with sotware 5.4.2.27545

Resolution/Horizontal Degree: 1850 subpixels/degree

Output is very precise (OUTPUT in software value 0.1 degrees) but Dayz resolution tracking is rounded (INTEGER VALUE ?) and the result is stuttered head movement.

With ALT+mouse for free head look around the movement is smooth with no issue.

Is possible to increase the resolution in decimal degrees for make Headtracking smooth like a mouse ?

I try to change sensitivity but the issue is same

<controller name="IRTracker">
        <limit name="doubleclick" value="0.500000" />
        <limit name="hold" value="0.330000" />
        <limit name="deadzone" value="0.000000" />
        <sensitivity name="vert" value="1.000000" />
        <sensitivity name="horz" value="1.000000" />
        <sensitivity name="curv" value="1.000000" />
        <sensitivity name="lvert" value="1.000000" />
        <sensitivity name="lhorz" value="1.000000" />
        <sensitivity name="lcurv" value="1.000000" />
        <sensitivity name="rvert" value="1.000000" />
        <sensitivity name="rhorz" value="1.000000" />
        <sensitivity name="rcurv" value="1.000000" />
    </controller>

Thanking you in advance, I send you my best regards
