Yay, we finally agree!
You want to explain how SM3.0 is involved with that? First of all we're talking DX vs OGL. Second, the two major advanatages are not specific to the specs of either SM3.0(PS or VS) or OGL 1.5/2.0/+, but design choices that were meant for D3 and which D3 was made to exploit.<font color=purple>In reply to:
As for SM3.0 I go back to the FX statement. Features mean little if the accompanying power doesn't make it worthwhile either. Sofar no one can show a single thing with SM3.0 that can't be replicated with ATi's feature set in any real-world app.</font color=purple>
<b>Doom 3 certainly seems to show the advantage...</b>
There's two things wrong with that statement, the next gen cards will have additional features that may or may not be the requirements for WGF1.0, the addition of FP32 HDR will be the default for UE3 based games. So when looking at it, IMO the future will not be defined so much by a set DX#.#x or even WGF# but by the subset features. Geometric instancing is in SM/VS3.0, but the X800s can do it because they have a superset to the standard features.But when even the next gen. cards are only going to be SM3, it somewhat shows that it will do us good for a while.
Doom 3 is a very shadow-insense game, and therefore benefits more from Shader Model 3 vs. 2; ( 3>2). Those benefits are shown through the various benchmarks you can find throughout the net. There, now that that's taken care of... 😀You want to explain how SM3.0 is involved with that?
Right, and just like I stated, in about a years time, coincidently around the same time as Vista or when the "next-next gen cards are released, features will improve. An example being Shader Model. It will improve from version 3 to version 4 (supposedly). I never said that would be the *only* feature. Because you're right about the subset features and all, and I totally acknowledge that.There's two things wrong with that statement, the next gen cards will have additional features that may or may not be the requirements for WGF1.0, the addition of FP32 HDR will be the default for UE3 based games.

Just to reiterate D3 is OGL not DX, so that assumption based on 3>2 doesn't fit.Doom 3 is a very shadow-insense game, and therefore benefits more from Shader Model 3 vs. 2; ( 3>2).
Well if your answer's going to be that quick and ignore the facts that much, then my response would be 3DC plus ATi memory management > not. Means about as much as SM3.0 and D3.There, now that that's taken care of... 😀
True but GF6800s can't support SM4 any better either, and WGF1.0/'DX9.0L' is definitely beyond them too, so the question will be 'will people code for SM3.0 any better than 'SM2' versus true WGF1.0 capable cards?An example being Shader Model. It will improve from version 3 to version 4 (supposedly). I never said that would be the *only* feature. Because you're right about the subset features and all, and I totally acknowledge that.
Ok, like I mentioned to RX8, there are some advantages (but a little costly IMO) to the SM3.0 class cards, but for the mid-range these seem beyond them. With the FP16 OpenEXR/HDR implementation in FartCry the GF6800U slows down to a level where the X850XT could replicate the same effect using 3 passes, with greater precision at close to the same speed. The greatest additions beyond the basics of PS2/VS2 are the vertex additions and one of the major benifits (geometric instancing) can be done by not only the nV GF6 and ATi X series but also the ATi R3xx series. As for dynamic branching, it doesn't appear that the heavy stuff that VS3.0 supports is also too tough for the 4x generation, no real tests yet on the G70 though but with 4X MADD it should be much better than the NV4x series.Ok, then I'm just a little confused. I'm not trying to be sarcastic, but then what advantage would having a SM3 card have over a SM2 card?
Depends on where you buy it from, and what type. I'm not talking about the X850XTPE BTW.An X850XT is way more expensive than the 6800ultra,
Explain that in relationship to what I said about FartCry, which is one of the only games to ship with SM3.0 support as you mention (BTW other that use it are SplinterCell ChaosTheory [worthwhile to turn on vs 1.1 but we'll have to see versus 2.0 now that they've patched PS2.0 support] ; and there are some add-on effects in a few other games like Painkiller). I agree 3 passes doesn't magically change the card, but if it can achive the same effect by doing that then that 'advantage' seems to be somewhat lessened when the time it take to do those 3 passes nearly equals the time it take the GPU to crunch through those extended shader instructions to achieve the effect.and 3 passes does not make a sm3.0 card,
It's not necessary for D3, the same effects can be achieved with far less, and that's what it's doing NOW with a few more passes (to do shadows). D3 seems to be the only one you guys can drag out to compare SM3.0 but it's not DX and the extended OGL API does not apply to D3. At least bring out Riddick if you want to try and discuss OGL, then you have a different support level, but even then you'd have to explain to everyone the benifits, because the visuals don't quite do it on their own.Doom 3 on a x850xt with 3 passes would be nice to see.
???apart from doom 3 which visually kicks ass in sm3.0
Huh, What? Not in the USA. In both PCI-e and AGP, you can get a X850XT platinum edition for the price of the 6800U, and the plain X850XT is cheaper.An X850XT is way more expensive than the 6800ultra
exactly my view Cleeve. 6800U @ 430/1200 isn't strong enough IMO, so the 6600GT or vanilla 6800 would be far from enough. As far as HDR in Farcry, I have never seen what a X800 series can do visually, but the GF6 does look very nice except maybe a bit too much at times.I'm very happy with my 6800U but Far Cry with HDR is not really playable
And now that there's the PS2.0 patch, I'd like tosee what the differences look like now that the X800 series aren't running under only PS1.1.Only game I have noticed the extra beauty in is SP:CT. In that one the X800 series got rooked so there is a definate IQ advantage.
