I'm using bootcamp to boot directly to windows. AMD has a program the says I need the catalyst drivers, but when I download the windows 10 - 64 bit driver, i can't install them. Has anyone done this that could point me to the right driver, just in case I screwed up. Here's what I have: 2013 new MacPro Windows 10 Pro - 64 bit. AMD FirePro D500 thanks.
