GPU graphs in Task Manager

Both my own laptops were upgraded win7-win8-win10 and both were giving
me different issues with a USB audio interface not working properly.

So I decided it was the right time to wipe and do a fresh install of
1709 on my "work" laptop, having done so I now get two extra graphs
(GPU0=Intel HD Graphics and GPU1=AMD FirePro) in the Performance tab of
Task Manager.

Now I've noticed it, MS do mention it was coming in 1709

But my "home" laptop which was upgraded to 1709, not a fresh install,
does not show a graph for the Intel HD Graphics, presumably (despite
getting an upgraded driver with 1709) it doesn't have a WDDMv2 driver
for its lower spec GPU?

That's about the level of it, dxdiag reports WDDMv1.3
