I have a 2012 rMBP 15" and I'm currently running Windows 8 in Bootcamp. I have no complaints, performance is great, but I see a lot of people going through a lot a trouble to install without BIOS emulation. With Windows 8.1 and Mavericks coming out in October, I'm going to secure erase my SSD, then install Mavericks and Windows 8.1. Since I'm doing that, I figured now is a good time to research whether booting without BIOS emulation has any benefits. I've done some searching here but haven't really come to any conclusions. I've seen things like: Faster boot time (I have no issues with bootcamp boot time) HDD performance (I'm guessing since I have an SSD and since the release of Bootcamp 5 this isn't really an issue) Audio doesn't work in Win 8 via EFI Based on that, I don't see any benefit to booting via EFI. Am I missing anything?
