I've attached a screen grab of my Activity Monitor comparing CPU usage between the Black Syphon app from VDMX and Max both capturing 1920x1080 50i @25fps from each input on a Blackmagic Decklink Duo HD-SDI card.  The Black Syphon app and my Max patch are both transferring straight to a Syphon server.

The Black Syphon app is using the Blackmagic SDK which from my calculations is not only using 40% less CPU (!), its about a frame faster in capture latency.

Cycling74, what would it take to build this Blackmagic SDK natively into Max?

Should we start a donation pot to get the ball rolling?!
