Does your Win10 actually have a display driver installed ?

Installed properly... can play games!

Firefox uses real time compositing to build the display
on the screen, and it composites 60 times per second.
It uses "acceleration" in the form of having the video
card do the compositing. If the OS is using the
Basic Display Adapter, I don't think that will do
hardware compositing. It would have to be emulated
or something.

Maybe it's a trick to "encourage" people to use Edge. Firefox under 8.1
definitely refreshed faster... The nano-second delay was like someone
taking a screenshot of your desktop.
