Got some good news! Since the Windows fall update the dGPU and the eGPU work perfectly together. Radeon and nVidia drivers are running side by side. Really awesome! (I connected the eGPU to the lower right port and an USB-C-HUB with Power Delivery to the upper right port)

So can one boot with the eGPU plugged in (from the start) with this update? That's what I typically do since I don't need the internal display. Everything works fine otherwise and hot-plug works normally.

@nanobit Would you share more information on how Windows 10 Fall update improves eGPU in Boot Camp? In Win10 1803 Spring update, it's possible to use Nvidia eGPU with AMD dGPU in the 2018 15" MacBook Pro for internal display mode acceleration.

Enjoying the native support. Just plush and have fun with TB3+AMD.

@mac_editor and @itsage today the disappointment: when I wanted to test a few things like hotplugging it didn't work anymore. I have no idea why. I plugged the egpu in when Windows was completely booted, BSOD like before the update. Then I started the Mac with the eGPU plugged in like I did yesterday.... but the internal display stays black. But the Radeon driver is running anyway and Windows recognizes the eGPU, but not the internal Display. 
I also tried some other configuration of external devices: USB-C-Hub plugged in to left side, no USB-C Hub... but always the same result.

Since yesterday there are a few more "Other devices" in the device manager: Basic System Device, NCM Control, NCM Data, PCI-Device, Unknown Device. 
Plus the Intel Gigabit Network Connection couldn't be started (error 10) but I had this issue before the update. I can solve it when I use the USB-C hub with the left sided ports. Seems like there's not enough PCI capacity.

I have a problem, when activating the standby of my macbook 13" 2018 with the rx 480 egpu attached. When activating it again after standby it will always freeze the whole system and a hard restart is necessary. Has someone the same problem or a solution?

I'm using the HP omen accelerator with the rx 480.

Bootcamp eGPU support works great for me and remains unaffected by Mojave. I managed to get NVIDIA eGPU support to work with purge-wrangler, however the external display is black and does not appear. This issue goes away in safe mode.

what do you mean by safe mode exactly? Smile

It appears that Nvidia support in Mojave is not as simple as waiting for updated drivers...

It is that simple. Your link focuses on CUDA, not the web drivers. CUDA is not necessary to run Nvidia eGPUs in macOS. In another thread Nvidia confirmed they're working with Apple to get Mojave support for the web drivers.
