Take it or leave it. ;)

Personally I'll be dissappointed if this is true, I've been waiting for Nvidia to bump up their features department. Hopefully angle independent AF is back and more !!

That stinks. Wish we could get a confirmation on the clock speeds and number of pipes now.

I never thought it would happen this round.The only statement I read concerning new features was that they were going to implement the af that was on the fx series cards.
(angle independant)

So if hdr+aa is a feature you definitely want,then ATI has a big leg up in this department.

Do you know if many games are coming out with this feature ?One would assume it will be standard at some time.Just curious if it will slowly show up much like SM3

to be expected i think, its not like they were going to do a major core change for the next release......just add more pipes to it. its dissappointing yes, but being the same architecture as G70 only with more elements i just didnt expect it to.

i guess NV are now doing what ATI did with R300->R420 just increasing the numbers and tweaking a little

theres far cry with HDR (of the open EXR variety) but in all honesty you can only play FC so many times before it gets boring

Splintercell choas theory is another game where NV cant do HDR+AA, and thats a good game too. Serious Sam 2 as well, only ATI got the HDR and AA.

others this year? who knows, U3 will use HDR and Ati will be able to AA+HDR in that, but wether NV can, who knows, im not sure waht type of HDR they are going to use.

I'm not a bit surprised. It's a refresh, and adding HDR+AA ability would require some major changes.

So they're finally bringing back some decent AF? That would make it a very compelling card for me if the other rumored specs are true. I personally don't care about HDR+AA though as I tend to bump the resolution instead of using AA in most cases.

I don't know why anyone would be surprised by this since the G71 is simply a die shrunk G70 with some extra pipes tacked on. Even if they introduce FX series AF to the G71, it doesn't neccessarily mean it will be anywhere near as effecient as ATi's.

Exactly.

Additionally, not that im putting ATI down for it, because really it is very nice to have this feature (i wish i had it lol), but the only Crossfire boards and MAYBE the X1800XTX can run this at any decent settings.

Yes, its just like ATI's x1900, its an x1800 with 32 more pipes. The 7900 will be similar, not "next gen" but a simple speed bump.

We are getting closer to launch, already into the lowering of expectations phase. Should be a great card. :beer:

It adds more lighting effects. If anything, it usually decreases performance.

I am truly impressed with the x1900 series that ati pulled out of thier hat. I was really starting to worry that nvidia was taking over...

Now ati needs to work on their crossfire..

It gives color more range which allows you to have a very dark color and a very bright color, high dynamic range is used to simulate how the eye adapts to light where in very dark areas your pupil widens more, if you expose it to very bright light while its that open, you'll see blinding light, that is very much what HDR tries to do, it gives a more bloomy effect to games.

I can't get HDR and AA to work in SC Chaos Theory, as soon as I change to SM 3.0 AA is grayed out, is there some trick to it?

Doesn't shock me at all but then it's not exactly a major thing in game development yet. In the next 12 months it should take off along with SM3 games becoming more frequent. ATI have done well to get a future technology in early, like nVidia did with SM3 which most of us would agree is coming in strong in H1 2006.

Chaos Theory automatically disables AA when HDR is used. To run it with both options will require a new game patch.

I think AOE3 has HDR+AA too. We'll have to see if newer games take advantage of this feature or not.

Add Ghost Recon: Advanced Warfighter (March) and Armed Assault (H1) to the list of HDR games this year. nVidia's definitely missing out on this feature, at least for a little while.

Yes, and actually it works on Nv cards also, through SSAA. It takes a major performace hit, but that's one way to get HDR+AA working on Nv cards.

No it doesn't. Nvidia cards do not have the required onboard logic to run FSAA (Full Scene Anti Aliasing) with HDR that uses FP Blending. AFAIK, HL2, which uses the Pixel Shaders to render High Dynamic Range Lighting, is the only game that allows any card to run HDR (Provided DX9 and PS2.0 support are present) and any card to run HDR+AA.

Are there many people that would rather turn HDR off than use it? Not talking HDR+AA just HDR. It just doesn't quite look right to me so I turn HDR off in favour of AA+AF.

I find it interesting a game like HL can combine AA + HDR and push it through the shaders and get great performance. But a game like far cry which is supposed to be using a version of HDR that has less overhead goes belly up with their HDR implementation.

I know people have said the makers of Far Cry are supposed to be using the better of the two implementations. But I think HL2 looks better than Far Cry and it performs much better as well.
