Yes, based on my test :)

The "main" is the one connected to the desktop you choose in "Show only on 1" / Show only on 2" box (I got the 2 VGAs connected to the same monitor, DVI for the NVidia GeForce and HDMI for the Intel HD Graphics).

Re-tested with Unreal (227j) and the updated Win10 1809 (build 253) using the DDRAW (DX6/7) renderer: only the main (choosen) GPU manages the rendering process, power saving config is simply not considered.

So that just leaves one question unanswered; is this the limitation in Windows itself or the drivers?

Good question!
I guess Windows.

OpenGL has the same behaviour of DX<DX9 (main GPU only).
