Vizard PPT tracking system

OK so I have an issue with a Vizard PPT tracking system using VRPN7

I have Vizard tracking eyes setup in VizConnect as PPT tracker. The issue I have is that the orientation is to sensitive.

Using PPT studio the system has been calibrated and thresholds are all correct and tracks fine in 3D. The eyes work fine in Unity through MiddleVR but shakes in Vizard.

When eyes are disconnect the scene is still, when the eyes are connected and placed on the head (or even floor) there is an error range of 0.1 in RPY values. Is there anyway to reduce the trackers sensitivity in Vizard in order to keep the scene still

This was resolved through a support ticket. This is a PPT X system that showed some jitter in the PPT eyes marker data. The solution was to optimize the thresholds and gains and increase the history length value in the 2D core stabilizer.
