The Ford seems a bit "low" for the bad roads in my area. :-)

Win 8.1 is definitely more responsive than Win 10 build 1607. There was
always some delay in screen refresh when using Firefox. Weird....

Does your Win10 actually have a display driver installed ?

Right-click start, select Device Manager, click the Display
Adapters one, and if it says "Microsoft Basic Display Adapter"
then you don't have a driver.

On my Test Machine right now, the "real world" install of
Win10 is using an AMD driver, and the adapter name is "HD6450".
That means my display is "accelerated" in hardware.

Whereas, in a Win10 VM I have loaded, the entry says
"Microsoft Basic Display Adapter". The display is unaccelerated.
(I did that on purpose.)

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.

My HD6450 was supported in Win8.1, but in Win10, there
were two drivers available. An in-box driver from Microsoft
for the HD6450 (with bugs in it, a CCC version). And the
second driver was a Crimson CCC2 driver package you could
get from ATI/AMD. And that one doesn't throw nuisance errors
on the screen any more.

If you did an Upgrade Install from Win8.1 to Win10 using
the various "Microsoft tricks to get you to upgrade",
that path would not install unless there was a display
driver. However, if you download an ISO from Microsoft
for Win10 and do a Clean Install, you can install
on hardware that doesn't have a driver. Then, the
screen is run using Microsoft Basic Display Adapter.

A side effect of MBDA, is you have limited resolution
setting choices. At one time, it would do 1024x768 max.
