Hi! I'm an all time newbie to the Mac world and I just purchased a Late 2013 Macbook Pro 15" Retina with the dual GPU in good faith that it would be able to run Windows with both onboard and dedicated graphics (switching between them depending on the load - just like in OSX). Instead, Windows only recognizes the NVIDIA 750m GPU which results in less battery life and much more heat dissipation. So I was just wondering if this is a well known problem or if it's just me? If anyone has any experience with this issue, do you know if there's any fixes and would OSX also be affected if I ran 'Parallels'? I really hope that some of you are able to help! Thanks!
