MSI Ge70 which graphics card is rendering?

In my experience onboard graphics is overridden by a dedicated card unless it's running hybrid SLI. From the looks of it both graphics cards are enabled on this MSI GE70 laptop. I haven't used it much for gaming besides a few low-demand applications so I can't really tell if it's suffering. However, the general graphics remind me of a 14" laptop I had 5 years ago. The screen is supposed to be far advanced and the resolution is 1920x1080. So how can I tell which card is currently working? Would it be possible for them to work simultaneously?
