late-2016 13" MacBook Po + RX470@32Gbps-TB3 (AKiTiO Thunder2 via TB2 to TB2 adapter) + macOS10.12.2BETA [itsage]^
I am researching if, using `spoof_osx_version` with rEFInd, it would be possible to a) improve Thunderbolt (re)connect under BootCamp and b) enable both Iris Pro and discrete GPU. The latter seems more difficult than eGPU as Iris Pro seems to be connected to internal display by default and external display requires discrete GPU (and switching doesn't work). I am using MBP late 2015, 15" with AMD GPU.
Any experience here with enabling both GPU's? Or at the very least, force always discrete GPU but with `spoof_osx_version` enabled?
If it helps for eGPU: I have patch the Intel Thunderbolt software to work under BootCamp:
I'm already tried the automate egpu a lot of times, but when I reboot I got the same screen.
do you know if it's possible to modify the EFI/Boot/x64 efi file on my external windows ssd? I've tried the usb thing, but when I select Efi boot after holding option on startup it just goes to OS X. I can't for the life of me get the internal egpu to stay on in windows.
