Hi..... proud new owner of a 15" Surface Book 2!
I cannot find where to tell the PC which GPU to use for an app. I had owned the previous Surface Book and there was an NVidia Control panel thatgave you all kinds of control over that.
The new Surface Book 2 doesn't have that installed on it and it seems that it's stuck using the crappy Intel Pro 620 GPU on every piece of software. I haven't modified ANYTHING since I unboxed it last night (in other words, I haven't screwed any drivers or anything up). If I look under Device Manager, it shows both the Intel 620 and the NVidia 1060 as graphics adapters.
I'm sure this is something very simple but thanks for helping!
