My MBP is using the intel iris as main display. I noticed this when I was looking at my "about this mac" window. I remember when I first purchased my pro it used my Nvidia card. Why is it using Intel Iris now? Does Yosemite regulate it? Work load and what apps/programs you're using and switch it on and off?
Got a tip for us?

MPB Uses Intel Iris Pro instead of Nvidia 750 GT?

It always uses the Integrated Display (Iris) unless there is an app/program/video/etc. that demands/requires the Discrete GPU to kick in.
It switches seamlessly between graphics cards depending on graphical power demand.
Macs with dual graphics have behaved this way since 2011.
great thats the answer I needed, wasn't sure if I just had a faulty card. Much appreciated and cheers!
