Nvidia Geforce 650m driver problem for windows 8.1 on macbook pro

Had the exact same issue on my mid-2012 pro retina model.

If I installed it on a MBR disk instead of a GPT+EFI disk, it did work though because only the nVidia GPU is exposed then by the "BIOS".

Even with the latest nvidia drivers ... no problem

I used wintousb to install win8.1 on an external USB3 SSD. Works smooth!

A Windows install via UEFI on a mid-2012 MacBook Pro isn't going to work. I have tried multiple times and it always ended up with a blank screen. Even if you could get it work, you'd have no sound. The legacy BIOS method is the way to go. See my last message in this thread with the VirtualBox install method. Slightly convoluted, but it works.

Hate so much this problem 😟

Wanted to play a old game I used to (Warcraft 3) and can't get it working. Same black screen when installing nVidia drivers.

you're suppose to use the apple bootcamp drivers

Apple - Support - Downloads

depending on your mac the correct driver would be in

5.1.5621

or

5.1.5640

You may want to look at Boot Camp: System requirements for Microsoft Windows operating systems - Apple Support to check BC versions compatible with your specific Mac model.

I have exactly the same problem. It's surprising nobody knows how to fix it

Another hint – never install Intel HD4000 driver, it'll mess everything up again.

2012 rMBP isn't supposed to work with EFI windows out of the box, and afaik 5621 drivers work fine with BIOS installations

Has this issue been fixed yet. I'm on a mid2012 retina 15" running win 8.1 and can't get drivers working properly

its the nvidia drivers from the bootcamp driver package

The culprit is more likely the OS, rather than the drivers. As a test disable/uninstall the Intel driver and test.

Oh, I will try that. This doesn't make me have to re-install Windows, I hope?

Thanks for your infor, may be I will have to use method 1 to check the Headset sound.

So just to clear things up, guys:

Currently there is NO way a 2012 nvidia 650m macbook pro will work 100% FINE with windows 8.1 via UEFI, correct? Only MBR?

Yes, that is correct. If you are adventurous, you can try editing the PCI registers, to make the EFI expose it correctly.
