Updating nvidia bootcamp driver macbook
Mac computers with a discrete graphics card often require more resources and Windows isn’t always very compliant.
Error 12 (lack of resources) or flickering/stuck Windows logo at boot are primary issues when connecting an e GPU in Boot Camp.
Now that Apple officially supports external graphics cards in mac OS (since 10.13.4), we’ve devoted more effort to set up and maintain a functional external GPU in Windows 10 via Boot Camp.
AMD XConnect and Nvidia Optimus are not available for these i Macs so our options are limited to either running the e GPU with an external monitor or Windows 10 1803 (manual graphics switching) for internal display loopback.
One positive news is the full bandwidth four PCIe lanes directly attached to CPU for Thunderbolt 3 connection.
