want to share with you a strange thing.
i have a maximus VIII gene + 6700k + 980ti and I used to install Sierra on that hack without using emuvariable64uefi.
yesterday I flash the new bios than I did I clean install and the result is that if I don't use emuvariable64uefi, Nvidia driver doesn't load.
so my question is: is emuvariable64uefi needed for Sierra?
I'm pretty sure that I did in the past month clean instal of Sierra without using it!!
