But you have to define "obsolete". I do not really care for the latest
and greatest; a generation or two ago is fine by me. And my pityful
MX440 run Xgl/Compiz fine enough, thank you. We could probably extend
that POV to a huge part of domestic computer user, who are not running
the latest and greatest anyway. Leaving aside CAD/CAM/EDA and other
professionnal endeavors for the moment, the only category of users that
really need "non-obsolete" (by your definition) GPU are the hardcore
gamers that must absolutely, positively play Doom 3 the day it come out.
Actually, what we would really need is good (relatively speaking)
support for the little 3D acceleration most popular onboard chipset
does. I am thinking, obviously, about Intel integrated graphic here. I
do not have any market data, but I would believe onboard GPU marketshare
dwarf gamer-oriented one.
That being said, we did had GLX drivers that performed ... half a decade
ago. The OSS Voodoo 3 drivers where, reputedly, on-par with their
closed-source counterparts. They where written professionnally and
funded by the manufacturer, too. So I would not dismiss the possibility
of getting decent OSS GLX drivers entirely.
Regarding the IP issue, that's one I just don't get. Where's the IP in
friggin' hardware interface ? For me, that would be like a CPU
manufacturer claiming it's instruction set is IP, and not releasing it.
My little theory (thin-foil hat on) is that GPU manufacturer do product
differentiation in software, and they don't want that exposed. Selling
black boxes is a pre-condition for this business model to succeed, so
there will be no published interfaces as long as they do.
