Has anyone tested this with NVidia cards on one of the newer Macs. It seems that both the MBA 2020 and the 13 inch Pro are having an issue with error 12 with NVidia cards, and unlike with AMD there hasn't been a workable solution that I have seen so far. Cheers!

This managed to work yesterday for me but it’s broken today. Not sure how it worked yesterday but I got a solid 12 hours of gaming out of my 5700xt yesterday no issues. Now I’m having all sorts of problems, half the time the April drivers from bootcampdrivers don’t install and I have to force quit, uninstall via control panel and then DDU and try again. And the other half the time they do install and are overwritten by the Microsoft AMD drivers that seem to download whenever they feel like it lol. 

Somehow my 5700xt managed to work for a split second today, then decided to error 12 on me after a restart to finish installing the April drivers. I’ve also had issues today where my internal GPU gets disabled and I have to solely rely on the external which causes some issues as well since the computer seems to no longer recognize the internal gpu (throws error 31 on the internal). Also just becomes a very stuttery mess

Also managed to crash the insider build after plugging in the eGPU on more than one occasion but I can’t seem to Reliably replicate it, it just happens when plugging in.

@dabesdiabetic, I'm using an iMac so it shouldn't just work on the Mac Mini. I think it should work on all the AMD cards. For my purposes I always turn on the eGPU before my iMac and have reason to ever hot plug it. The EFI bootloader shouldn't be hard to remove but if it works this way why risk it?

Also, for people having trouble with Windows 10 automatically installing a wrong driver and ruining the settings of the correct drivers, the method I used to solve this was to change all the policies I could find regarding delaying or disabling automatic Windows 10 updates by running the gpedit command. I believe there is a tutorial on how to find these policies on the Windows Central website. If you google "disable Windows 10 updates" or something similar I think the article from their website should pop up.

Oh boy, I can confirm (quick test) this is working with the Windows fast ring update, version 2004 v19628.1. Specs of my build are in my signature :). Before I had to fiddle around with booting from the egpu switcher thing, now it works out of the box, fingers crossed, when booting with the egpu attached.

Played a bit of Doom 2016 (foundry level) @ 3440 x 1440 with everything on high. But my CPU got hammered, throttling at 100 degrees Celsius, meaning my FPS dipped to 40 - 45. The bottleneck was clearly on the CPU, Doom has a real nice FPS counter with CPU / GPU seperation for that. On my MSI gaming notebook with an i7-7700HQ I reached 60-65 FPS with the eGPU and 70-80 FPS with the built in gfx card. Jebus, they don't make this eGPU thing easy. I'll need to try out a bit more with different bootcampdrivers and different games I suppose. That, or the i9 really is not suited for this kind of thing, too many cores and games not being properly tuned for these kind of setups? Next up, the witcher 3 :).

It's been working through fast track for at least 2-3 months now. Glad you were able to do it.

@paul_malin, the polaris card should work with older builds of Windows 10 and current fast track builds straight out of the box.

Thanks, the Blackmagic eGPU is recognised now with me having installed the fast track build of Windows 10, however does take some plugging and unplugging of the thunderbolt cable to get it to recognise sometimes.

The one thing I still cant get though is the LG Ultrafine to work through the BlackMagic when using Boot Camp. Windows only shows the internal Macbook Pro display. If I plug the Ultrafine directly into the Macbook it works, and if I use Mac OS X it works through the BlackMagic, however it seems like there is a driver issue when using the Thunderbolt Display through the eGPU in Windows 10.

Anyone else have an idea of where I would start with this? Audio is coming through the monitor and the audio driver shows as Ultrafine, however no video.

@paul_malin, this has been answered many times. You need to boot Windows with the eGPU already plugged in. This way Windows will disable igpu and only use egpu

Thanks, tried that a few times now and no go. Just not getting any video output to the LG Ultrafine when connected through the eGPU in bootcamp.
