We have noticed increased jitter with Vuforia 2.8.7 versus Vuforia 2.6.7.
I posted a video comparision using one of our image targets we are using that ranks 5 stars.
The video link is https://www.youtube.com/watch?v=mDfouj_iLWQ
The comparision was done with a clean install of each library into Unity 4.3 on a MacBook Pro.
Extended tracking was not activated on the 2.8.7 image target.
Was there a built-in filtering in 2.6.7 that has been removed?
Is there something about this setup or image target that would explain the increased jitter?
