hi cgc,
thank you, for your posting, I think i am coming along now
Pentium. Still, I am glad to read that a lot is done by the hardware (graphic card) and an average PC with 1GHz+ should do it.
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)
latency actually is of importance, since the video should be like a mirror to the performer. but some ms are ok.
well, with 20fps you are getting latencies bigger than 50ms very fast (this is just 1 frame!)
I think all my questions are answered, only if there is a preferred graphic card, to be used?
if you want openGL-hw-acceleration try nvidia- or the new radeon-cards.
