Any successes yet with RX5700 (XT) on Bootcamp Windows 19.03 with AMD dGPU?
Suffering the fate of early adopters I can't get the RX5700 recognized on my MBP2018 w/RP560X using an Akitio Node and the most recent drivers from Bootcampdrivers.com. Any pointers what I could try to troubleshoot are welcome!
Unless the Bootcamp drivers are not working with the RX5700 eGPU setup that is?
Yes, maybe it's still a grey cat and they don't work. You still can go to run it without Bootcamp drivers and abandon the idea to accelerate the internal display. (Just disable the RP560X and use normal Radeon drivers for your eGPU).
The effort seems too Titanic atm. Since I can't test the card otherwise (no separate case/mobo) I might send it back and wait until I hear and read about more successful builds (@fasaso seems he has had some luck).
well, all I can say is exactly how I did it, maybe it'll help.
I first downloaded a fresh installation from Windows (1903) to bootcamp. Then I downloaded the Bootcampdrivers.com drivers and installed them according to the instructions in the corresponding file "Read me". After the restart everything ran slower because the internal graphics card was not recognized. I did not connect the external graphics card until this step. I shut down the mac again and connected the graphics card
Now you should be able to bootcamp normally. That's all I did. I hope I could help you.

Starting with Radeon Software Adrenalin 19.7.1 version, the RX 5700/XT are supported in Windows. They also work in Boot Camp mode on Mac computers. I've tried both and they worked fine [RX 5700 link] [RX 5700 XT link]. The drivers are not optimized for eGPU use and the performance loss through internal display mode is greater than Polaris and Vega.
