Maybe this is related to the type of GPU on the laptops? I
don't
have
any
noticeable lag that I am aware. Here is my GPU for further
reference.

The
work-around for a bug or other performance issue that is
causing
a
screen
reader to lag is not to "get a better computer." I understand
that
computers with less RAM can't be tested by some people because
they
don't

Could this possibly be fixed? I do notice a slight lag, less
than
a
second, as soon as the preferences window opens, but the voice
tab
is
running smoothly here. So this one is either not affecting me,
or
has
been fixed. I can't tell for sure either way. > # 2. Orca

Confirmed.

Again, in the places where I see it, it's really not extremely
sluggish,
just a bit noticeable. So I will say it's confirmed here. It >
