Very interesting. So it is more like a romance than a business deal, and then in the end it's still the suitor who is willing to buy the biggest diamond ring and give the "bride's family" the biggest payoff who finally gets the prize.
There was a title I read about (can't remember the name now) where Nvidia supposedly wrote shaders for the developers, but kept copyright on them, insisting that their work was only to be used for the Nvidia path, so there was some kind of deal done beforehand for some of the dev-rel stuff.
Yeah for the most part, well as a developer I wouldn't want to go exclusive if another company can also help me lol, thats the way I look at it, I'm sure others do too, unless the developer is big enough to sustain themselves at endless costs . Yes I know nV still does keep copyrights to some of the shaders they write for developers (specially around launch time of a new product, if that developer has access to nex gen cards), this is the whole thing about the g80, ATi wanted a couple or more developers, (I know there were at least 2 developers involved), to release some "code" later on I found out it was indeed shader code, which nV gave the permission to release but only after the g80 was launched. Now doing code that only works on nV cards, if it did happen it was probably before my time, my company joined with around the time the Fx was launched, but didn't really get serious till the gf6.
