A few questions about Bootcamp & Error 12

While waiting for my eGPU I've been reading a bit about bootcamp setup and a few things are still unclear to me. So hopefully someone can share their experiences.

 

1) Does error 12 happen only on Macbooks which already have a built in graphics card? 13'' with integrated graphics work OK or are those affected too?

2) How is the latest windows version (20H2) behaving? Still having issues? 

3) If I'm doing a fresh install its best to install Win10_1903_V1 and then disable updates, right?

4) Is this issue related only to 5700XT? Would I avoid it if I buy 5600XT instead?

 

Once I get the answers I'll edit this post and add them here for others to see.

Eh, I can only repeat what other members have said:

In time, you will know what it's like to lose (to error 12). To feel so desperately that you're right. Yet to fail (cuz error 12) all the same. Dread it. Run from it. Destiny (error 12, yo) still arrives.

Ok, that and Windows 20H2 needs the Hackflags 0x600  work-around.

Or disable automatic updates if you’re installing Windows 1903v1.

@mini-i5, For me on Windows 20H2 the 0x600 fix does not work.

Sorry to hear. You might want to read @agent post.

Maybe reinstalling 20H2 using the Windows Update Assistant tool will work for your RX 580 as well.

@mini-i5, Thanks for the info.  I did read it and had no luck even with the 0x600 fix.  I did not try 1903, but given I have a MacBook Pro 16 I'm concerned about using an older build for a newer laptop. 

 

I also realized I don't use bootcamp for anything other than games.  I then realized the two or three games I play work on Mac and run equivalently well with the eGPU in macOS.  There are some old games I can't play in macOS that I've limped by with VMware.  I don't want to go done the EFI route or similar as if I do that I can just Hackintosh a machine and dual Windows (or just put Windows on it for the 1-2 games I can't play well on VMWare.

 

Would I prefer bootcamp, yes, but it's not a great option if I wish to use the eGPU.  Can still use the 5000m of course.  They perform roughly the same.  I wanted to upgrade to a 6900 next year, so figured bootcamp may perform better but I'm doubting how much support will be in macOS in the future for ePGU.

Good points. I can see Mac eGPU support reaching its apex in Big Sur with 6800 XT, 6900 XT and Pro model drivers. 

Even with their talented designers, there’s no quick way for Apple to speed development of its own pro-level GPU to rival AMD and Nvidia.

That’s what the rest of the Industry says, anyway.  

So whatever happens next will surprise people.
