Multiple Graphics Adapters (related to 4.1 QFE / very low fps rendering)

I absolutely agree, but disabling the Intel HD530 makes Unreal revert to the ‘Microsoft Basic Render Driver’ (as I stated before), making Unreal run completely on CPU. Not exactly what we want … Disabling the Intel HD530 doesn’t get me any further.

As an illustration: when I monitor what applications are running on the GPU (using the NVIDIA GPU Activity screen - can be enabled from Geforce Control Panel), it is very clear that Unreal Editor is not running on the GPU.
