"PAUSE and STUTTER every time "

Agreed it's always been to some extent in Pro Tools.
However, different systems of pro tools as-well as plug-ins do this to different degrees.
From barley noticeable adding sends, EQ's and gates..All native and stock to 3rd party plug-ins and dsp systems that pause and catch up.

Different native apps like "Live" do this better. (Now) it's vaporware to think avid has this. They're promoting it may be collaborative but not likely to be seamless during soft patching and inserting.
