I don't need an extreme zoom to notice that it introduces considerably more aliasing then nVidia. I was griping about that fact a year ago and was continually told by numerous ATi supporters that I was seeing things(although at the time I was blaming it entirely on ATi's LOD bias selection when that wasn't the whole issue). You are right that ATi is within DX specs, it is the extra steps that nVidia took that makes their solution better in this case. Once you are used to the higher level of filtering quality on say the NV2X parts, the R300 offerings do look noticeably inferior in terms of filtering quality(although significantly faster).

depends on what kind of games you are playing,
if it does affect gaming performance with AA and AF on, by all means turn it off,
who wants smooth edges but lagging ...??

No, false. That colour wheel isn't terribly useful at showing realistic gaming conditions.
nVidia's AF method can potentially sample more angles but ATi's AF method tends to stay sharper for longer distances on the angles it does sample.
You pick a real game and try to break ATi's AF. Trust me, it's almost impossible. On extremely rare occasions you'll spot such an angle but for all practical purposes it's superior to nVidia's method the majority of the time.
Show us then. I don't believe for a second that at 1600x1200 with 8x AA and AF you can see jaggies.

I have noticed one thing about nVidia's drivers... not EVERY edge gets AA treatment. In Call of Duty, I just finished the mission where I'm on the boat and you destroy the radar computery things. Well in the next mission, you start on a boat... certain parts of the hand rail are not anti-aliased. I'll take a screen shot in a few minutes.
This is with 4X Quality AA...
here's a bitmap... enlarge it to show it better (about 500KB)

the red area is pointing to alpha textures, which mulitsampleing cannot do anything to fix. the alising being pointed to by the green arow is due to the ordered grid sampleing method nvidia uses, nearly horizonal lines will show noticeable alising.
"Some antialiasing settings require a large amount of video memory. If the mode you requested requires more video memory than available and you see unexpected results, try selecting the next lower mode, and so on, until you achieve the desired result. You may also want to experiment with different screen resolutions, refresh rates, and/or color depths until you arrive at a setting or combination of settings for antialiasing to work."
This was written as a AA tip in the Driver User's Guide. Guess it explains it all... mostly.

No wonder VIAN thinks AA sucks. Stupid Nvidia doesn't even fix the jaggies all the time. I played call of duty demo with a 9500pro and didn't notice jaggies like that.

Have a look at this screenshot , I think quality is superb (jpeg has made it worse though).
NFSU: 1280x1024 2xAA 16xAF performance in 9700Pro.
Now tell me how big the jaggies are.

I can still see many jaggies, although the picture looks great, it is compressed and it would look a lot worse in real life.
It looks better, a lot sharper in textures and with less jaggies in real life.... I can tell you
Edit: and while playing looks a lot better
Good quality but as you can notice antialiasing isn't as good as ati's. I'll post a pic of taht circuit in some minutes.
I agree with VIAN to a degree.
I don't think they're useless, but I don't think they're a big improvement either.
I have a 9800 but I rarely use AA or AF, the major exception would be Freespace 1&2 where I use AA since they can't go higher than 640x480 and 1024x768 respectively.
Sure, if I turn on AA/AF in Max Payne, CS, or Quake, I can see a difference, but when Im actually playing them rather than just looking at them, I see no difference whatsoever compared to "vanilla" 1600x1200.
Of course I never play any flight sims, the closest to that would be the Freespaces.

Look at the difference between texture quality in the houses for example, it's huge with AF on. Have you seen my screens with and w/o AA/AF? The difference is very big, and I can notice it while playing a lot.
But is it worth the performance drop. Depending on your framerate likes. 30fps is enough. Who here plays Halo at much more than that?
Wow, look at the difference between the screen shots. Yours is dark and mine is light.

It is al least in the games I play. They look much better and have no lag at all. Maybe it is another story in another games, but not in mines hopefully
