Enabling iGPU in bootcamp on 2017 27" iMac

[Kwyji]

iMac 27" (2017), running i7 and RX 580, with 24gb ram. I have a 500gb Bootcamp partition on the 2tb fusion drive, running Windows 10 pro (Fall Creators Update).

Now with the i7 7700 I should be able to stream netflix in 4K within Windows 10, however for this I need to run the iGPU on the CPU, rather than the Dedicated RX 580.

Does anyone know if/how it can be enabled?

PS: it absolutely baffles me that Apple is not supporting 4K streaming in Netflix or even iTunes for that matter... Especially considering the quality of this 5K screen...

I don't think that's possible; I think the display is connected directly to the dGPU.

I don't know a great deal about Netflix, but why is 4K not supported with the AMD GPU?

It's all about DRM. On PC Netflix has only allowed 4K streaming under very strict conditions (Windows 10, edge browser or store app, and Kaby Lake processor, maybe one or two Nvidia cards). The iMac in theory matches the requirements but in practice the iGPU on the i7 CPU is disabled and this one apparently should be used to allow 4k streaming
