I installed bootcamp to be able to run windows games on my Mid-2012 mbp (non-retina). My CPU is the 2.6 quad core i7, I'm sure of that, but I'm not exactly sure which GPU I have. The specs of my computer say that I have an Intel HD Graphics 4000 AND and a NVIDIA GeForce GT 650M with 1GB of GDDR5 memory. Which one of these two GPU's does Windows use? The game I'm trying to play (Titanfall) will work with well with the NVIDIA card, but not so much with the Intel one. Can somebody explain this stuff to me?
