Mac Pro Crossfire Boot Camp

Tried MSFS 2020 using Parallels 16 (configured to use 6 cores and 32gb ram) on 2018 Mac Mini, 64gb Ram, Blackmagic eGpu Pro (Radeon Vega 56). Even though at MSFS program launch it says computer does not meet min specs, it does launch.

  1. Short gameplay of gta 5 running on a Mac Pro late 2013 (Dual gpu) with BOOTCAMP driver Win 8.1 in FPS: 40-60 on max Settings CPU: 12-Core Intel Xeon E5 GPU: 2x AMD FirePro D700 (CrossFire) OS: Win.
  2. Crossfire however is supported in bootcamp as confirmed by rob. He ran two 3870 in xfire while in bootcamp on the 2008 Mac Pro and I believe that it will work just fine in the new ones. The Mac Pros have the multiple PCI slots, as you can get certain cards times 2 and 3 (and times 4 I thought at one point).
  3. For Mac users who also need to use a PC at work, home or just with specific applications, there is a solution. Using Boot Camp Assistant, you can install Windows 7 on your Intel-based Mac computer in its own partition. You’ll have a dual-boot system with your Mac OS on one partition and Windows on another.
  4. The only caveat is that this doesn’t work on OS X, users will need to be running Windows in the Mac Pro’s Boot Camp partition if they want to take advantage of CrossFire mode. The accompanying graph clearly shows increase in performance with GPUs “CrossFired” on Windows 8.1.

If you use Boot Camp to run Windows on your Mac, you can visit the AMD website to download the latest version of their drivers for Windows. These Mac computers use AMD graphics:

  • 15-inch MacBook Pro introduced in 2015 or later
  • 27-inch iMac introduced in 2014 or later
  • 21.5-inch iMac with Retina display introduced in 2017 or later
  • iMac Pro introduced in 2017
  • Mac Pro introduced in 2013 or later
