I started this build mostly to see if I could. I use a MBP for work so wanted to see if I could use it as a gaming computer, but not losing my Windows install if I upgrade. It totally works, with a lot of weird things. I just wanted to share my experience for everyone else.

System specs

  • 2017 MBP 15"
    - Mojave 10.14.6 (RTX 2070 doesn't work there)
    - Radeon Pro 560
    - Intel HD 630
  • Samsung X5 TB3 SSD
  • External 27" Dell Monitor


eGPU hardware

- Asus XG Station Pro
- EVGA 2070 Black

Installation steps

Installing Windows on SSD
The TB3 SSD acts as an internal drive so it sounded possible to install Windows on it and keep full functionality. I heard that external drives without TB3 have a lot of issues running Windows. After trying, it totally does work fine. I made a boot drive on a USB stick with the Windows installer and bootcamp drivers on there so I can reinstall in the future if needed. This makes my MBP totally modular.

Gotchas: I did accidentally unplug the drive while Windows was running. I don't recommend doing that. It was really unhappy. I also have had a few issues of unplugging the drive while on the OSX side and the next time I booted to Windows, it reinstalled drivers and all my games were acting like they weren't installed anymore (the files were still there though...). I don't actually know what caused that but doesn't happen too often. I'm trying to remember to unplug the SSD when the laptop is completely off.

Windows 1803
After a very normal Windows installation from the USB drive, I installed Bootcamp drivers and a few other things. Mouse drivers, security updates, etc. I plugged in the XG Station and after about 30 seconds it recognized it but didn't have drivers. GeForce Experience recognized the card then and installed fine. I ended up flashing the eGPU with the ASUS tools online but they're quite garbage and don't really tell you what they're doing. I don't really even know if that's needed either. A few restarts and settings changes, I had a working dual screen setup. My laptop screen was running off of the Radeon, my external monitor was running off the 2070. No bootloaders or anything. Doesn't matter when I plug the eGPU in (preboot or hotplug), it just seemed to work.

I've done this twice, once at the beginning, once again after messing everything up a Windows Update which I talk about below. No real issues either time. I'm still surprised at how easy it was.

Windows 1903 (.1 - .295)
I wanted to play Gears 5 a couple weeks ago and it required a newer version of Windows. I naively updated Windows and problems started. I can still run the eGPU on earlier versions of Windows 1903 but if I have the eGPU connected during boot, Windows hangs before the blue spinner should start spinning and forces me to hard restart the MBP. Weirdly enough, after a hard restart it does boot but the eGPU isn't recognized. In Device Manager, the port is yellow banged but not error 12. If I disable the port, then enable it, everything starts working again. I have to do this every time I boot up right now.

If I hotplug after Windows is already running, the eGPU is recognized immediately, but weirdly enough I completely lose sound. I don't have any other audio devices besides the built-in laptop speakers so I don't know what's happening. I need to do more tests. This method would be way more convenient, except for the audio issue.

Windows 1903 (>.295)
Error 12. No go. The first time this happened I just reinstalled 1803, which was fine, but still wouldn't run Gears 5. Updating again and then uninstalling the specific Windows Updates (KB...356 and KB...384 I think are the ones) seems to bring me back to ^ so that's what I've been doing. I just disabled the Windows Update service to prevent it automatically updating. A lot of others have this problem, so I don't have any more info here.


Benchmarks

Destiny 2: ~80 fps on High
Borderlands 3: ~65 fps on Medium

This setup is way quieter and about the same performance as my SFFPC build with a 1060. If Windows doesn't fix the issues, I'm tempted to convert this back to a dedicated PC. It's really convenient having a completely modular setup though but everything since 1903 has been frustrating.
