Peter Barker and I have recently completed testing of APSync for the NVidia TX1 and we've also updated the wiki to clarify how you can set it up yourself. Equivalent versions for the RPI3 and Intel Edison were released a couple of months ago (release notice).
The biggest improvements for this version of APSync over previous versions are:
OpenKai included by default which makes using the ZED camera quite easy for indoor navigation (for Copter and Rover) and forward distance monitoring (Copter only for now).
APWeb which is a small web server that allows easily setting parameters and calibrating sensors. This product was original developed by Tridge for the SkyViper GPS drone (thanks SkyRocket for sharing!).
APSync also includes the previously available features including the Wifi telemetry and video (a wifi access point called "ardupilot" with password "ardupilot" appears).
By the way, in case you're not familiar with APSync, it's purpose is to make integrating ArduPilot with companion computers a lot easier by providing ready-to-go images that help developers and pro-users to get started quickly. There are other options as well listed on our Companion Computer wiki page including Maverick.
