Are you saying that the reviewers don't use AA, or that I don't? I'd have to disagree with that. I've posted links that support my position, can you post links that support yours please? I'm open minded, and if you post links to videos that illustrate this large difference you say exists, I'll retract. Heck you can even post them yourself on ABT if you want, then we can all watch and decide for ourselves.

I mean if we?re going off screenshots, can we compare ATi?s AF to nVidia?s AF with screenshots and conclude the cards are equal? Of course not. In fact (and rather ironically) ATi?s AF often looks ?better? in screenshots but in actual gameplay that isn?t the case at all.
Personally I'd say ATi and NVIDIA AF are pretty close to equal- are you saying that you believe NVIDIA's is superior? I realize NVIDIA's is closer to angle invariant, but you're the first person I've seen say there's a noticeable difference. Seems like something I would have likely been posting if this were widespread knowledge- source?

There are visible and clear improvements in actual gameplay when going from 4xMSAA to 8xMSAA. That is a fact.
You and others have been saying that, can you post links to your source, or better yet videos that illustrate? I only remember reading the difference from 0X-4X is large, and 4X-8X is small. As it's impossible for CSAA to have worse AA than 4X (sample patterns: 4XMSAA = 4/4/1, BX MSAA =8/8/1, and 8X CSAA = 8/4/1) it seems likely my theory that 8X CSAA is somewhere between 4X and 8X in quality. People should note that although 8X MSAA offers double the coverage and color sampling, I've never seen anyone put forth it offers double the image quality. The jump from 4X to 8X to 16X is seen as diminishing returns- do you have contrary info?

Right, but how many nVidia hardware accelerated PhysX games are there? UT3?s five maps that nobody plays don?t count, and neither do tech demos, nor do games that will never be released to the public.
How do you know nobody plays them? I'd bet $100 more people play them than the 8 year old games I had never heard of you were upset about on nZone, or Serious Sam 1 with a specific patch you were after NVIDIA to fix. Unless you know everyone or have some method of monitoring them, you can't say this.
What abnout GRAW2 and Warmonger? They are games people can play now. Mirrors Edge launches next month, Cryostasis in February, do you have information they won't? Or information about all of the other upcoming games? (e.g. Bionic Commando)

Now compare your list to the thousands of 3D games that can have 8xMSAA enabled.
How about I compare it to DX10.1 or tesselator enabled games instead, as those are vendor specific features the X2 has?
Better yet, how about link us to games where 8X MSAA is less playable on a GTX200 SLi rig than a 4870X2, as you seem to be implying the 8X MSAA is a reason to choose ATi over NVIDIA.
I say the IQ benefit is small and offset by better transparency and CSAA, and that this card will offer 8X MSAA at a level the difference in ATi and NVIDIA won't matter.
Please provide links that disprove what I say, rather than just saying I'm wrong and pointing at your single card results which aren't applicable. You could get both of the cards and review them for ABT perhaps.

I have about 80-85 games installed right now where I can enable 8xMSAA. I have two PhysX titles and neither of them support hardware acceleration, so hardware PhysX makes no difference to them. So remind me again, why should I be excited about hardware PhysX?
There's no reason for you to be, the people who own the current games and will be buying the games launching next year are the ones who should be excited. I don't own any sailboats, only have powerboats and hand powered boats, but I don't say "Why should I be excited about a nice sailboat?" and totally discount their value.

Show me the majority of new games (not tech demos) shipping with hardware PhysX support and then I?ll get excited enough to install the PhysX driver. Until then it?s a niche at best, like DX10.1.
OK so niche products aren't worth having to you. Ironically you made a point about no TSAA in OpenGL, and that's a niche these days. So I guess to you OpenGL is the niche to care about, PhsyX is not. Whether you care about PhysX should be irrelevant to everyone else presumably- it offers higher image quality and changes gameplay in games current and upcoming. The fact they aren't the majority of games doesn't change anything. Used to be 3d games were few and far between, made most people want to play them all the more.
Were you saying "There's only a handful of 3d games, I'll stick with good ol' bitmaps"?
Eh? Since when are Call of Duty 4 or Bioshock five year old games?
When you show me a GTX295 can't run these games acceptably at the resolutions a X2 can, and answer my previous questions, we'll talk. Maybe I'll post some benches as I'm in a good position to do so. (hint)

So let me see if I read this correctly: you?re saying 8xMSAA doesn?t make much difference but 8xCSAA does, even though it?s objectively and mathematically provable that 8xCSAA is inferior to 8xMSAA?
I didn't say that at all. I said 8XAA offers a small improvement over 4X, that 8X CSAA offers a smaller one, but the difference in either and 4X isn't enough to get worked up about.

That simply doesn?t fly. If 8xMSAA provides no benefit then neither does 8xCSAA, making it a useless feature. But if 8xCSAA provides a benefit then 8xMSAA must also provide one because it?s objectively provable that it?s better.
You've said this many times in this post, I posted links to others who agree with me and screenshots to back my position. I ask again, can you do the same? I also never said it's "useless", please don't misquote me. I said the difference in 4X MSAA and 8X MSAA is much smaller than the difference in 4X and 0X, that 8X CSAA provides some of the small improvement by having double the coverage samples.

I have no trouble acknowledging the strengths of either vendor which is why I don?t make ridiculous flip-flop arguments depending on which IHV is currently leading or what is the current ?in? thing. I?ve extolled the virtues of nVidia?s combined AA modes for years despite the fact that basically no-one uses them.
OK sounds good.

OpenGL games don?t need to launch; there?s already an installed base going back over ten years to GLQuake. Additionally there are large community followings of source ports such as Doom, Quake, Quake 2 and Descent 1/2. Additionally, many popular legacy games like UT99 have updated renderers that run best on OpenGL.
PhysX needs launches because it needs games for it?s almost non-existant market base, namely titles supporting hardware acceleration on nVidia GPUs.
Everything starts somewhere BFG, and there are games now and many on the way in 2009.

Again with the still screenshots which are generally useless for showing IQ differences unless they?re zoomed. Anyone that uses AA in gaming knows that.
Ratchet doesn't know what he's doing? Have you told him this over at B3d? In any case, I'm just waiting for you to post links to contrary proof still, because I've used 8X AA and have missed the awe inspiring difference you seem to be alleging and the reviewers always miss.

8xCSAA?s effectiveness diminishes on polygon intersections and it?ll also fall back to the base 4xMSAA on stencil shadows, when running TRAA, and also anywhere where coverage sampling may fail for a given pixel.
8xCSAA is definitely better than 4xMSAA but 8xMSAA is even better. The only place where 8xCSAA may rival 8xMSAA is on first-class polygon edges and only if all pixels succeed in their coverage tests.
I understand there are differences and fallback with CSAA, and realize MSAA is by definition "better", but think it's a diminishing return compared to 0X-4X, and not a whole lot better than 4X.
I also say NVIDIA GT200 SLi solutions offer good 8X AA performance, sometimes better, and the small difference in IQ and small performance lead in some games doesn't justify anything. I also say it's offset by transparency deficiencies for ATi.
