MuFu said:Sure, but one of the main reasons Creative swallowed Aureal was to finally bury all the Patent 990 litigation. Although A3D 2.0 was a fantastic technology I really don't think Aureal were head and shoulders above Creative in terms of tech, as so many people believed. In 10K1 the latter probably had the upperhand when it came to handling multiple audio streams in a desktop environment and superior MIDI features, to name just a couple of areas. Plus they already had a very exploitable engine in EAX and of course there is no reason why they wouldn't have embraced Aureal tech since the aquisition, as nV surely will have embraced 3Dfx ideas.
3dfx and nVidia were in court too, and 3dfx was set to win You think nVidia didn't want to kill that before it ended?
nVidia will and is embracing 3dfx ideas, slowly but surely. GeForce4 has a good chunk of Rampage's 2D engine, keep in mind... but that's the only explicit use of 3dfx tech thus far.
I suspect some of NV30's tech IS 3dfx-influenced, for example the 4 colour-ops per cycle with two textures (4x2 architecture) which can do 8 any-other-ops per cycle (the whole 8 pipelines debacle)... 3dfx were good at tricks like that.
I just don't believe Rampage was as ahead of it's time as you claim. They canned it because it really wasn't all that great - if it was, we would have seen explicit use of associated technologies by now.
The only explicit use so far is GeForce4's 2D engine, as stated.
I still say it's because nVidia doesn't want to admit their most bitter rival was in fact better than them... because that's what they'd be doing if they used specific tech from Rampage.
Besides... what explicit tech would they use, anyway? It's Rampage as a whole that's really significant (or at least, was). It's still only a DX8.0 part, when you get right down to it, and a lot of its really neat tricks are done better in some aspects anyway (for example, 'borrowing' Z-check units from other pipelines while multitexturing + MSAA comapred to having multiple Z-checkers in a singe pipe). Rampage as a whole would have been the first DX8 core, and would still be ridiculously fast in a select few situations.
