I run Firefox on it.
The graphics stack is pretty impressive. And one
of the things that impressed me, is the time it
took to go from "barely working" to "tuned". Only
a week or two. Whoever did the work, "had experience" :-)
It wasn't run like a lot of Microsoft projects.
It had real Linux people in the pits.
One of the layers of the graphics stack, seems to be Terminal Services,
and I suspect that's how it gets to the Windows desktop.

The renderer seems to be wired up (judging by Task Manager info), but...
it's not very fast.

GLXGears doesn't seem to be accelerated.
However, in W11 Task Manager, the hardware GPU indicates it is
running at 40% at the moment, to make these paltry frame rates
for the animation.
