MBP 2019 16” on BIG SUR, Windows 10 Bootcamp.
All stock.

My problem.
I bought this thinking it’s going to be A Plug and Play combo via BOOTCAMP.
But turned out since the BigSur update all EGPU’s are done for?

Current Build 

razer X core with pin adaptor to adapt the 8pin +8pin + 6 pins for nvidia msi gpu. 
GPU : nvidia msi 2080TI 

What happens?
When I plug in the thunderbolt device while on bootcamp the sound come out, but the installation gets an auto cancelation.

I tried to make a Bootable EFI partition on Mac OS but since BIGSUR upsate not one of my USB stick get’s detected.

To do: Create my signature with system and expected eGPU configuration information to give context to my posts. I have no builds.

Big Sur 11.1 works great with my Vega 56 eGPU and Bootcamp.

I’ve found EGPU support (and all TB device support) for the Mac Mini to be much better in 11.1 than it was in Catalina. 

On my Mini, booting between Big Sur and Windows just works with an eGPU and all thunderbolt devices connected.
