I have a very stable Hackintosh (Asus P8 H77-M PRO) with a Win10 & Sierra Dual-Boot.
I installed a BlackMagic Design Decklink Card for professional Use.
I have checked the SDI Input latency on both Win10 & Sierra.
Windows gets about 3 frames delay while sierra gets about 5 frames...
I have installed El capitan 10.11.2 Over my New Clevo P750DM with a single discrete Nvidia 980m (No integrated GPU available on this system)
I have followed all the instruction carefully from this post...
