30fps is 33ms per frame. I'd expect that to be fine for most free-space gestures (for musical instruments you generally want <10ms, but that's most noticeable with discrete impulsive events like hitting a drum pad, and even then is pretty manageable).
Is the frame rate really the limiting factor here, or something algorithmic in the tracking (like smoothing out noise)?
