Guys, I'm curious whether anyone succeeded in installing and running Windows 7, 8 or 10 natively (in UEFI mode) without any glitches on MBP 15" 2014 (MacBookPro11,3) but with NVIDIA card completely disabled, running only on Iris Pro? Does sound, brightness, wifi, camera, sleep, external displays, etc. all work or are there some driver issues? I'm about to buy this machine, but would like to turn off NVIDIA GPU under Windows. If anyone could confirm this it would be really, really helpful. Thanks!
