?intel iris drivers on macbook pro retina 15" 2014

Question

hi all, i need help i'm lost
it's been 3 days trying to install the intel iris graphic card drivers for the iris 5200 that is shipped with nvidia 750m on the macbook pro 15" retina 2014 and i'm not able to install the drivers.
i installed the preview version of win10 and i rolled back to the preview version of 8.1 both 64bit
and there is something weird, because my bootcamp is only able to install a preview windows version, even having a pro version with product key of 8.1, at the end of the installation, windows say that the changes on my computer can't be saved, so no working windows 8.1 pro
as you are aware, bootcamp download the intelLegacyHdGraphics64.exe together with all other drivers like the nvidia one.. but only the iris drivers will be not installed. the error message is always the same: this computer does not meet the minimum requirement for installing the software.
so, i went to intel site and i downloaded all available drivers, the intel SDK for ocl applications... 2014.exe, the "opencl runtime 14.2x64. package.. installed correctly.
what i'm not able to install are all drivers i could find on the site for the iris.
Intel® Download Center
but i'm getting always this message: this computer does not meet the minimum requirement for installing the software.
the nvidia 750 works as expected, and i did try everything to install the iris drivers.
i also tried to uninstal the nvidia drivers also using the device manager, not just simply disabling it.
and after booting again.. the iris is not listed in the device manager, just the microsoft default display. and trying to install the drivers manually failed too, but that was expectable since there is no intel iris menu from which to pick manually the drivers.
if i try to install using the compatibility tool i get the message that the os is not supported
I'm lost lost lost
did someone try to install them? maybe had luck under a win7? or it is a lost war?

I Want to use luxrender and luxmark on windows too
the benchmark score of the iris 5200 in osx mode is 4880 while the score of the nvidia is 900/1100
that is a huge difference in speed
I am unable to search http://www.luxrender.net/luxmark/ for benchmark data. Is there another way to get to these numbers? If you use the nVidia that is currently exposed to windows, do you run into any issues for Rendering?
Edited: on my acer running win7, i disabled the intel graphic card for the sake of Nvidia 330m from bios, and it works
this should be possible in win 8.1 too? as i know those setting aren't anymore available as bios mode.
is there a way to unhide the iris 5200 and permanently disabling the nvidia 750 in windows?
You may want to start by looking http://forums.macrumors.com/showthread.php?t=1658931.
btw maybe you can answer to this. Running luxmark in yosemite, when i benchmark using cpu, iris, or cpu+ iris the fun becomes noisy as it should, but if i benchmark just the nvidia card the fun doesn't start. and this should be not normal at all.
This seems to be normal behavior from my experience. The integrated GPU (CPU+Iris) produces much more heat than the discrete nVidia. If you do not have a case on your MBP, put your palm on the bottom panel, and run both tests. You can also use something like iStat to look at the temperatures of various components while running tests.
