@joshuan_flores, the internals and pci layout are different between the base model and the upgraded model so it's doubtful that it'll work without some changes and experimentation.  Maybe if you followed a build for the 2019 MBP Base model you may have more luck.  They're virtually identical save for the keyboard.

First of all, a BIG thank you for the guide! I tried so many guides, but this one is the only one that took away Error 12. 

 

Unfortunately there is a but...two questions:

 

1. The Vega card now works, as per there are no Error 12 in the device manager. But, when playing any games, the performance is like there is NO GPU at all, tried Starcraft 2 for instance, and since my the Intel Iris is disabled as well, its was like playing on an old Pentium computer from the 90's 🙁

 

2. As I disable the three other PCI ports, I won't be able to use my USB C hub (where I the HDMI to my external screen is connected to), and I guess I can work around that. 

Now, what I can't do is to set the screen setup to "External Monitor Only" in Windows. I can duplicate or Extend the screen, but, and Im just assuming this, that it puts my MBP to a test in regards of performance having to display a game on both monitors?

USB functionality is unaffected by disabling the PCI ports.  Your USB C hub should work just fine.  They just no longer have connection to the thunderbolt controllers.

Your HDMI cable should NOT be connected to the USB-C Hub, it should be connected to the HDMI port on your eGPU's graphics card.  That explains why you're getting no hardware acceleration.

But the connection from the USB C to my computer is a Thunderbolt cable.

 

And the HDMI is connected via the eGPU to the monitor directly. 

eGPU connected via thunderbolt to the computer. Device Manager shows that it all works OK hardware wise but I don't get the acceleration still as you say.

A Thunderbolt 3 cable, while overkill, is still compatible with all USB-C devices even though they can't saturate the Thunderbolt 3 cable's bandwidth.

 

While both screens are turned on, go to windows display settings.  Set the monitors to "extend these displays". It will also help if you select "Identify" so that you know which display is which.  In the top window that shows the silhouette of both screens, make sure you have the external screen actively selected, then scroll down and check "make this my main display".  This should kick in the hardware acceleration.

I'll have to test a bit with the USB C hub I think, because it didn't give me any love Smile

 

However, the other part with making my monitor main screen sure hit the spot! Thank you again for the great guide! Im gonna save it till the day Apple starts supporting eGPUs better Grin

I got my new mbp 13 2020 10th gen, but it is impossible to install windows 10 1903 or 2004 version on an external drive. After the bootcamp drivers are installed keyboard and trackpad and wifi not working and while I try to update with a usb mouse it always crashes and I get this message on a blue screen. Any suggestions are welcome. I have security to none although I tried with medium but the installation does not work, and able to boot from ext drive is on. I have also disabled SIP.

@tsakal, I have not tried external Windows boot volume on Apple T2 Security Macs. I'd recommend partitioning 100GB for Bootcamp then install all games and apps on the external drive.
