NetworkIK does a good job of smoothing out a lot of the jittery motion and vibrations resulting from fast and sudden movements affecting your HMD, controllers and vive/tundra trackers for others.
However, this is still quite jarring for the user locally.
When using mirrors or stream cameras, particularaly for recording videos or streaming live content, this often creates a poor and distracting experience.
I propose that a form of user-controlled local smoothing is implemented, perhaps through the quick menu, where the user can decide how little or how much smoothing (or interpolation) is applied to their local tracking experience.
The minimum value could be what it is today, and the maximum could be the same amount of update rate that is applied for NetworkIK.
I can see this being extremely beneficial for dancers in particular.
This could even be a more complete version of an already existing suggestion for hands https://feedback.vrchat.com/feature-requests/p/motion-smoothing-option-for-hands-accessibility
