the hw-acceleration has to be used by the package in order to work
(no-na). in most (if not all) cases, hw-acceleration means
3D-hw-acceleration and not pixel-processing.
Gem is openGL-based which means, that it will use hw-acceleration (to do
3d-things and to display images, but not to do pixel-based effects).
however, things like blending to (moving) images can be done in openGL
(alpha-blending)
pdp has these openGL-packages, which will give you some acceleration
too, but i m not sure, whether you will have any benefit when doing
image-processing (i don't know about textures).
but i think, pdp has mmx support, so image-processing will be much faster.
with gridflow i really don't know, but i guess you will have no
hw-acceleration at all (but might have MMX also)

well, with 20fps you are getting latencies bigger than 50ms very fast
(this is just 1 frame!)

if you want openGL-hw-acceleration try nvidia- or the new radeon-cards.
