Installation steps
MacOSX:
Plug and Play
Windows (Recommended Windows 10 Build 1809)
- Install BootCamp through Mojave
- Boot into BootCamp (without eGPU plugged in) and install BootCamp drivers, restart
- Install all Windows 10 updates, restarting each time
- After everything is installed and up to date, plug in eGPU and restart until you get display on the external monitor
- Internal monitor will be black at first, then will turn on
Benchmark
- I'm having some issues getting AIDA64 to finish the benchmark, so I will post some benchmarks later
Comments
- I can't get AMD Radeon Settings to install updated drivers for the Vega 64 (it says no AMD card detected), so I will try installing the drivers manually.
Comments (eg: how has the eGPU improved your workflow or gaming)

Thank you for sharing this nice build! Are you using the Apple provided Boot Camp drivers or the modified Radeon drivers from Bootcampdrivers.com?

I am using the provided Boot Camp drivers, as installing modified Radeon drivers broke my bluetooth connection.
So I figured out how to install updated drivers for the Vega 64:
- Download newest drivers from AMD Website
- Extract the exe with 7zip
- Go into Device Manager, select the Vega, and click updated driver
- Select "Have Disk" and direct it into the folder that contains the setup for Video Driver
- It will restart a few times, screen will screw up, etc but it will update
Game performance improved MASSIVELY. Without updated drivers, I was getting random fps drops in GTA V, now it is locked at 60 max settings with VSync on.

Does that same Radeon driver work for the Vega 20 dGPU? How long do you wait until the internal come back on?

Since I just installed the 19.1.1 Drivers for Vega 64 only (through device manager), the Vega 20 GPU drivers don't seem to have been updated. The internal display comes on immediately if I boot without eGPU plugged in, and to get Vega 64 working again I have to hotplug and start the restart sequence again.

Thank you for the additional details. Does the Vega 20 dGPU actually work for internal display eGPU acceleration through Windows Graphics option?

Only when the eGPU is not plugged in. When the eGPU is plugged in the Vega 20 is completely disabled (device manager shows that the device could not be started) and AMD xConnect is being used to power the internal display. This can be seen through both Device Manager, and the Task Manager (only GPU that shows is Vega 64). I have not tried eGPU and only internal display yet, with no external connected.

This is (unfortunately) a standard issue all MacBooks with AMD dGPU share: The AMD dGPU can't be used with an AMD eGPU in Bootcamp. It's almost a completely showstopper for Windows users. Acceleration on the internal display on this particular MacBook model (15-inch 2018) is not possible at all.

Oh, fantastic!... my last information was that the procedure was not practicable. I will test it with my dGPU Radeon Pro 560x and eGPU Radeon RX 580.
