"Although Vista isn't going to be available in retail until at least January 2007 (with rumours mounting of further delays), the major graphics cards vendors such as ATI, NVIDIA and S3 naturally already have their responses to DirectX 10 very much planned out. However, thus far it's been ATI that have made by far the most noise regarding this next release of DirectX, as they seemed determined to leverage what they clearly feel is their advantage (both architecturally and regarding their experience) in this upcoming arena. To this end, they have been travelling far and wide to promote both DirectX 10 and ATI's plans towards supporting it (Without giving away too much about their first DirectX 10 product, R600, of course) to the press."

Where are you guys trying to access it from? Maybe its to do with a filter blocking the address. Needless to say it works for me.

[DCR]

Dunno...worked for me. Interesting too...

link worked for me second time around.maybe the site was down momentarily.

I did something similar a while ago as well: Here (http://www.overclock3d.net/articles.php?type=3&id=47&page=1&desc=ati_talks_about_directx_10)

it's funny how often ati slides get put up. you never see them from nvidia...

techpowerup puts out both sides slides and nvidia has tons of them as well...

The uptake of new functionality, the use of geometry shaders in particular, will also be dependant on the speed of first-generation hardware at processing these effects of course - In the aforementioned example, I've already heard rumours of poor performance from one IHVs DirectX 10 part, which suggests that we might not see geometry shaders used 'in anger' for quite some time. As ever, time will tell.

Hmm. I wonder if 16 combined vertex/geometry shaders for are not enough in G80? Perhaps 16 shaders used for vertexes is fine, but when they are partially used as geometry shaders it limits vertex performance too much?

On the flipside, it could just as easily be a flaw in R600's design. Perhaps when geometry shading is used, it drops the shader pool available for vertex/pixel shading to much because of weaker individual shaders.

Perhaps it's none of the above, and one just is sub-par in general.

If that rumour is true, I'd think it'd have to be G80...As afaik ATi has not sent samples to AIB parters while Nvidia has.

Just random speculation on my part, and perhaps a unfounded rumour on his, but that is an interesting and enticing comment coming from the Senior Bastard.

I got a feeling that this depth of field crap is going to be used waaaay to much like HDR. It's like it gets to a point where they just put it in there , even when it's not needed, just because they can.:rolleyes:

Well, anyway I think ATI's bet is for sure more DX10 compatible than nvidia's, even when they get lucky and end with the right amount of pixel/vertex/"geometry" shaders.

But again, game devs won't want to close the doors to nvidia owners, so they will use the exact amount in G80, which funny enough, IMO is going to be the "standard" Microsoft wanted to be for DX10 :D at least for first gen of DX10 cards.

If not imagine this: next Crysis game engine goes and uses 24 pixel shaders, G80 only has 16 and there you go, all nvidia owners can't play the game 100% in DX10. So the devs will have to use the nvidia shaders if they want to be fully compliant with all the cards in the market.

it is very stupid to say "the game engine uses 24 pixel shaders" - the engine is shading pixels with the pixel shader. The engine can and will render graphics even if the chip has only one shader unit, but it will take very long and frame rate will be low. Speed depends on number of shader units and core clock speed

Now if you are talking about 24 bit precision, that's a whole ohter story...

Even if devs do have to pander to nV owners (as in the new FX :rolleyes:) then ATi can always optimise its unified architecture to run in the same ratios. Its not a problem for them because they can effectivly have any configuration they want. Much more flexible. On the other hand G80 relies on the devs doing exactly what it needs to run at peak performance.

Still, its too early to really speculate on whats going to happen.

(Off topic: did I miss something while I was away because a large number of people seem to be sporting huge OCZ ads in their sigs and not just the people from OCZ it seems. Anyone mind PMing an answer to me?) EDIT: got an answer no more PMs please ;)

[LOE]

more flexible, but also much more complex... we will have to wait and see how ati does

nvidia decided to be cautios, I bet there is a good reason behind it

[ahmad]

Unified shaders are handled by the drivers and software. It's already implemented in the xbox360 and works great obviously. Every frame generated will use a different vs:ps ratio, to allow effective usage of all the available shaders.

Remember that the r600 will also work in dx9, so I assume they have a "default" ratio in place for that and similar situations.

[tys90]

To this end, they have been travelling far and wide to promote both DirectX 10 and ATI's plans towards supporting it

Huh? Where? What? When?

Did I miss something?

[Cobalt]

Ati have defo been making a lot of noise about DX10 and unified shaders. nV on the other hand have said very little on the matter. So either ATi has something killer and knows it and nV are having some trouble, or ATi is compensating for poor performance with marketing tricks and nV has an ace up their sleeve.

Of course the the best situation is that both cards are just as good as each other and a price war begins. w00t for teh consumer! :toast:
