When Turning Camera Twists?

[ArchAngelAlien]

So I just recently got my TrackIR 5. It has been a bit difficult to setup and I am still trying to figure out how to set it up properly.

One problem that I am having, is that inside the camera software, when I check my YAW left to right doing a 180 degree angle, when I hit the 120 degree marker on either left or right, the pointer begins to roll without my head doing so?

When I move to 120 degree right, it rolls right. When I move my head left to the 120 degree marker, it rolls left. All while my head remains level when turning.


I even have a dead-zone set to my roll, because I use it as my lean in Arma 2 and don't want to interrupt my sprint.

Even with the dead-zone in roll, the camera still attempts to roll left or right at 120 when trying to reach 180 successfully with no interruptions from the other motions.

How much roll is being added at 120?
