Ha! That's the whole damn point Dave. Use your head. Just because ATI

back to my original example of the aic7xxx cards. The alternative to
their simple hardware design is something like the BusLogic or QLogic
cards that are far more complex. Your assuming that because the ATI
cards are getting more complex and people are less able to discern their
makeup just by reading the specs that the nVidia cards are doing the
same, nVidia is telling you otherwise, and you are just blowing that off
as though you know more about their cards than they do. Reality is that
they *could* be telling the truth and the fact that their card is a more
simplistic card than ATIs may be the very reason that ATI has ponied up
specs and they haven't. Therefore, you can reliably discern absolutely
*zero* information about the nVidia cards from a reference to ATI specs.


Certainly possible. Maybe all their real IP is in the code, although if
that was true, letting opensource peope ahve the programing spec and
have to do their own drivers wouldn't expose that IP. I have no idea.


Even without opening up the code, but with programming specs there are many graphics driver guys out there, given the specs out it would not be too hard to have a decent driver, without the Nvidia IP. In that case there would be no question of IP violation.

Or maybe somebody can do a clean room implementation provided Nvidia agrees to some NDA, and the resultant work is acceptable to Nvidia provided that it is free of their IP.. Many hardware vendors do resort to these to get their hardware working properly under Linux, and in some cases, the Linux driver has proved to be a better driver than their Windows counterparts, albeit with lesser gimmicks/features.
