Twas time to upgrade to chief x7 (from X4)- yep I'm slow... so I took the opportunity to upgrade my pc to a Microsoft Surface Book i7 with dedicated Nvidia GPU. Been running for years on an old desktop with Quad core Q6600 and a Nvidia GTX 460 graphics card. Don't do heaps of 3D so the old system has lasted well.
On the new Surface Book everything installed without a hitch but when I look at the About tab in Chief it says its using the internal Intel GPU and not the faster dedicated Nvidia GPU.
I have loaded all current updates etc for Windows 10 and surface book firmware.
