blikblum: the thing is, the "selected adapter" in dolphin's settings has nothing to do with the gpu actually being used. It is controlled by the driver. Adapter=1 is always wrong because the driver is actually only exposing 1 gpu at a time, there is no ability to select.
Well, it doesn't work for me... I have to Right Click > Run on NVIDIA GPU or add an entry for Dolphin in nVidia Control Panel... Using the latest nVidia drivers for windows
In the graphics config dialog, if I run Dolphin normally, it lists only Intel HD 4000, if I run through context menu, it lists only nVidia GT635M...
I don't know how more clear I can be:
The list that dolphin presents you is not related to what's actually being used.
