Hi John,

In addition to Mitch's links, these might also interest you as you
mentioned experience in a 3D animation studio:
* http://doc.qt.io/qt-5/qt3d-overview.html
* http://doc.qt.io/qt-5/qt3drender-framegraph.html

As for optimizations for Qt Quick, I think the Qt Company staff
members involved are in the best position to provide you with the
relevant info. Note that it is currently summer holidays in Norway, so
most of the staff are on leave till the end of July. Here's a small
peek at some of their recent work (although these are components built
on top of Qt Quick, rather than Qt Quick itself):
