Still I was pretty sure that ATI would not go for CG since this is Nvidia's thing and if it adopted it, this would make it look like a follower but not the leaders.
Nvidia will allow anyone to use this language at no charge, but it still seems to be the only one ready to go for it big time.
But this could cause problems because if ATI designs its own shading language, this would put developers into an invidious position, as they would have to decide which language they should use.
