Using gpu-switch script to force Windows to use the iGPU results in a black screen when booting Windows and then it restarts over and over so that I have to get into Safe Mode and run the dedicated.bat script. It showed up on rEFInd but it sort of kept looping and flashing some text on screen (it seemed like the procedure worked since somewhere there was a 'press any button to continue' but clearly it didn't as it stuck again on that screen. Further searching on the forum took me here to aa15032261's modified version of apple_set_os.efi. As it was noted on the thread, I tried using the rEFInd spoofing function and yet I wasn't able to use my iGPU.

Even with this I wasn't able to boot it from USB stick, so I proceeded to put it in /Volumes/EFI/custom but again it seemed stuck after the 'set vendor to Apple Inc.'. Then I found this and tried apple_set_os.efi. Wasn't able to use automate-eGPU.efi on USB stick cause it didn't show up neither in rEFInd nor in the 'option' menu so I put automate-eGPU.efi in /Volumes/EFI/custom folder and it did show up in rEFInd but it got stuck in the loading screen, forcing me to shut down through power button. So this led me here and to goalque's solution and this is the list of things that I have tried (unsuccessfully): Here's a screen of the iGPU not being usable: The goal is to get Windows to use the iGPU for soft tasks and the dGPU for gaming and heavy tasks. Windows sees correctly both the iGPU and dGPU in Device Manager but I'm not able to use the iGPU resulting in Windows using only the dGPU with consequent overheating, fan noise and battery drain. Followed this guide to override the DSDT in order to make the sound work in Windows Created a Partition Manually (as the Boot Camp procedure would result in a black screen with 'no bootable device detected'), installed Windows 10 on it via USB and then installed all the bootcamp drivers.

I'm getting here after a (way too) long journey with no success in enabling the iGPU on Windows 10 and I really hope someone in here can help me out as I'm running out of options.
