NVIDIA's GeForce 8800 (G80): GPUs Re-architected for DirectX 10

Prey Performance
With Prey being based off of the Doom 3 engine, only with some enhancements, scores tend to be quite a bit lower than many other games. At our maximum detail settings, dual graphics cards were previously required to play at the highest resolution. Now, a single 8800 GTX card is once again able to equal the performance of X1950 XTX CrossFire, which is no small achievement. The reduction in pixel and vertex processing power results in the 8800 GTS performing quite a bit lower, although it still manages to outperform 7950 GX2 by a small margin.
Quad SLI continues to be a disappointing prospect, providing no performance increase over a single GX2 card. The release of GeForce 8800 pretty much seals the fate of Quad SLI as well, as it's doubtful that NVIDIA will continue to invest time in optimizing the QSLI drivers when they have new GPUs that could make better use of optimizations. We can only hope that most of you didn't get sucked in by the marketing.

They did the same thing with the original Halo, porting it (and slowing it down) to DX9. MS seems to think making Halo 2 Vista-only will get people to upgrade to the new OS. [:rolls eyes:]stmok - Wednesday, November 8, 2006 - link
How else are they gonna get gamers to upgrade to Vista? :)(by cornering them into adopting Vista, using DirectX 10.0)
Its sad and pathetic at the same time.
DirectX 10.0 should be a "transitional" solution...That is, it covers both XP and Vista. This allows people to gradually upgrade their hardware, and if they wish, to Vista. What MS is doing now, is throwing everyone (developers and consumers) into the deep end, and expecting them to pay for the changes. (I suspect some would be put off by this, while the majority will continue to accept it...Which is unfortunate).
Great article BTW. Interesting to see the high-end stuff...But I doubt I can afford it in this lifetime!
I have two questions!
(1) Any chance of looking at a triple video card setup?
(I saw a presentation slide which had 2 video cards in SLI, while a third showed something else on screen).
(2) Any idea when the GF8600-series comes?
(mainstream market solution).

http://www.gamedev.net/reference/programming/featu...">This article was written by a friend of mine back in April after an interview with ATI. Perhaps this will clear some things up.

When you break all hardware/software ties to something that has been around for 4-5 years? Its not that easy making it "transitional". From a software perspective, D3D10 is not compatable with XP in the least.I for one, think this is a step in the right direction.

Supposedly all of the changes to the WDDM make porting DX10 back to Windows XP "impossible", although I'm more inclined to think the correct term would be "difficult" and you also have to add in "it doesn't fit with MS marketing protocol". WDDM is quite different in Vista however, so maybe there's some substance to the claims.cosmotic - Wednesday, November 8, 2006 - link

Due to the size of this article and the amount of time it took to get ready, let me preempt any comments about the spelling and grammar. I am in the process of editing the final document as I read through it, and there are spelling/grammar errors. If they bother you too much, check back in an hour. If you read this an hour from now and you still find errors, then you can respond, though it would be useful to keep all responses in a single thread like this one.Thanks in advance,

On p 12 (gamma corrected AA):"This causes problems for thing like thin lines."

"If DirectX 10 sounds like a great boon to software developers, the fact that DX10 will only be supported in Windows XP is certain to curb enthusiasm. "I believe this should say "DX10 will only be supported in Windows Vista..."
Not to be rude, but shouldn't the article be edited BEFORE being published??
