Hey guys,

I've been having a little problem with the graphics card I have installed in my Mac Pro 5,1, and I need some help with it. Little bit of background first, I'm not using Bootcamp for to run windows as my Mac doesn't support it, so I just downloaded it from an external usb drive and option boot between MacOS and windows to switch between the two. Whenever I use the stock graphics that came with my Mac Pro (AMD ATI graphics that shipped with the Mac Pro, everything works fine, but these graphics are super slow compared to my RX 570, which I will add, works perfectly when in MacOS. However, whenever I boot into Windows 10 and switch the GPU from the stock graphics to my RX 570, the RX 570 spins up until the startup chime, when it just stops and doesn't display anything. Furthermore, I can't download any drivers for the graphics as the AMD driver app needs to detect the graphics for it to work. Does anyone know a fix for this?
 
I recommend to post this in the forum exclusively for the Mac Pro:
EDIT: i also recommend to add more info e.g. hardware, BootRom version, OS version etc.
