Windows 1803 is rolling out and there are some significant changes for eGPU. For the most part, Windows users will have finer control of multiple graphics cards. We can now specify which GPU handle apps depending on energy or performance preference. Here's a screen capture of an RX 580 eGPU paired with 2016 15" MacBook Pro (dGPU disabled).

There are some concerns with Bootcamp mode. Through early testings, error 12 is a pesky annoyance that becomes a bigger issue in 1803. This applies to both 2016 and 2017 15" MacBook Pros. I did not have time to test with Nvidia eGPU yet. The only one way to resolve error 12 is to disable PCIe x16 Controller 1901 to the dGPU.

The 13" MacBook Pro can resolve error 12 by connecting the eGPU to left Thunderbolt 3 port closest to the TAB key. In the Touch Bar model, the PCI x2 Root Port #9 [9D18] to the right TB3 ports needs to be disabled. In the non-Touch Bar model, the PCIe x1 Root Port to the iSight camera needs to be disabled.

If you have a functional eGPU in Bootcamp Windows 1803, please share your experience so that we can help other members should issues arise.

For MBPs seeing error12 in Windows but do not have a factory 'large memory' area, instead of disabling the PCIe Port, please try @yifanlu's Clover bootloader build (which adds apple_set_os.efi) along with a DSDT override to allow eGPU allocation into 64-bit (> 4GB) space.

If this tests out as a good solution we can massage it into a more palatable step-by-step guide with pre-compiled DSDT files for candidate Macs.

I'm not sure how Windows handling all those settings will improve something instead of leaving it to Nvidia.
Looking at the release notes in the latest drivers every unresolved issue regarding laptops/dual graphics/optimus is described as: "....this setting are operated by Windows and Nvidia has no control over it".But i guess...time will tell.

Argh... I'm still on 1709, best I look up how to prevent updates as the last thing I want is error 12 with my Nvidia card!

Just updated to 1803, mainly because it was harassing me and I had a backup drive image.  Install took about 20 min or so, I did the update with nothing plugged in at all.  First boot with the razer core v2 attached I think it spontaneously rebooted after I logged in.  Next boot was fine but egpu was non functional. 

I went into the Device Manager, all the usb devices plugged in were there and working, including the Core's USB RGB Lighting device, but only Video Card present was AMD Radeon 460 Pro.  I finally found the gtx 1080 under "other devices" as "Video Controller (VGA)" and told it to update drivers, which took a while but worked, then asked for a reboot.  Before rebooting I disabled PCI Root Complex 1905 to ensure the GTX 1080 would have enough resources.  Just did a quick 3dMark test and got the same results as before the update.

Only other oddness is a 453MB partition assigned to drive D: that wasn't there before, I think that is a known issue with 1803 and not Mac-Specific.

I'll report back in this thread if I encounter any other surprises.

just installed a clean Bootcamp on MacBook Pro 2017 (R-560) with Mantiz Venus w/RX Vega 56 plugged in. The installation went smoothly, eGPU was autodetected, AMD drivers installed by Win10 update.

I got 2 external monitors hooked up through the eGPU, both switched on full resolution (4k). Ran Heaven and Geekbench 4 tests, RX Vega works fine in both tests.

So I guess the issue is now solved - at least new Macs and Radeons work nice together out-of-box, both with macOS and bootcamp Win10

To do: Create my signature with system and expected eGPU configuration information to give context to my posts. I have no builds.

I believe it’s only the 15inch models sadly for me. From what I’ve read it’s related to the firmware which was updated on the Mac side rather than anything windows related. I’d love to be using my AMD card but it just doesn’t play nice with windows.

Hi, just installed update 1803 to my MacBookPro 13 Late 2016 (with touch bar) everything ok! The only issue that I have is when I shutdown Windows 10 and restart the system in MacOS (10.13.5 beta 4), the first time MacOS hangs at login screen, it needs a second reboot.

You gotta be kidding me? Don’t tell me the 13s work now too or are you using rEFInd or another fix?

edit: just seen your build guide. Not plug and play then.

Thanks for the info - looking for an easy solution for a 15” MBP 2017, and looking at XG Station Pro with a Vega 56 or RX 560. Care to write up your experiences regarding installation, eGPU acceleration etc?
