Currently trying to get bootcamp working with my Mac Pro 5,1 using a 1080ti (Unflashed) Installed Windows 10 via usb using a modified bootcamp 5.1 installer and the Ati card, I had to unplug the apple ssd to get the Windows installer to work but other than that it was fine. Bootcamp drivers installed and I can boot into Windows 10 using the Ati card. When I plug in the Nvidia card and boot into Mac OS I'm using bootchamp to restart into windows / bootcamp drive. However since there's no drivers for the 1080ti on the windows os (assuming this is the problem) I'm unable to boot, black screen. I've tried downloading Nvidia drivers while the Ati card is plugged in, however the installer doesn't allow me to install without a Nvidia card and this is the only way I can boot. Also tried resetting pram etc. SIP is also disabled. Just wondering whether using a 1080ti with win 10 is possible or not / if there's any info on how to get this working?
