Don't know for sure, but in general, since Flash does input and display in
the same thread, the question is whether you are processing the response
too slowly and events are being dropped, or the pen just doesn't output
fast enough or there is some code in between like in the browser or in
Flash itself that gates the input rate.  Many years ago, most tablet and
pen hardware couldn't keep up with fast hands.

If you use the Pen in a native app (Windows Paint, Adobe Illustrator,
etc), does it go fast enough?  If yes, then you know the device and OS is
fast enough.  Then you could try a test app that instead of drawing on
each mouse move, just queues them up and draws them "later" so you see if
Flash can get enough events without dropping any.

Then profile what happens in response to a pen event.  I could imagine
that Flex might be overthinking on each event.
