Updating Windows to 1903 and 1909 is not affecting the function of the eGPU, it still works flawlessly.
However, my favorite games, Civilization 5 and Battle Worlds are not working anymore with these updates.
Consequently I downgraded the system again to Windows 1803 - and it works.
The interesting thing is, that the games are working under Windows 1909 and the described build, attached to my Mac Mini 2018.
@hans-st, Thank you for sharing this fun build. Does your 2014 Mac mini has Fusion drive? If not you may still be able to get a flex adapter for PCIe SSD connection. That would allow for M.2 eGPU adapter which is a better performing connection.
Thank you for your suggestion, it sounds interesting.
However, I am using already a PCIe adapter in my Mac Mini 2014. Some years ago I added to the original 1 TB HDD a 250 GB flash drive via an I fix-it PCIe adapter and created a fusion-drive. Later I replaced the HDD with a 120 GB SSD.
By the way, I set back the PowerColor Mini Pro to it's original set-up with the Radeon RX 570. It works under MacOS perfect with both Mac Mini's and very reliable under Windows 10 with the Mac Mini 2018. The only challenge is Windows 10 (1803, 1903, 1909) with the Mac Mini 2014. But this is for me not a need, only a challenge on which I tinker around from time to time - I have to admit, so far without success.
