Could there be any PS3 games with no AA?

They wont have AA if there using HDR i should imagine, can RSX do ANY kind of AA with HDR??

You can apply SSAA to FP16 buffers with G70 tech.
You can have MSAA with HDR on G70 tech, but you can't use FP16 buffers. However, you can do what you need to do wrt HDR in shaders, which are fully floating point btw, using a buffer that can have MSAA applied. Not everyone will use such techniques, but depending on your requirements it may be the best route to go.

MSAA can't be used on FP16 render targets on RSX, so the only two solutions available for HDR plus AA on RSX are either FP16 plus SSAA (But that costs way too much bandwidth) or HDR implemented on a shader level plus MSAA.!eVo!-X Ant UK said:
Heavenly Sword has HDR and AA, using a custom INT format instead of FP for the HDR. We don't yet know if RSX supports MSAA and FP buffers either, or is still restricted in that way same as G70.!eVo!-X Ant UK said:

Volumetric/3d architecture, allows for designs with more memory allocated closer to the logic, also molecular memory can be quite fastShifty Geezer said:When that setup finds it's way into a home console, let me know
Actually you'd also need an incredible memory system. It's often overlooked, but bigger faster processors are only as fast as the memory that feeds them, and that's not progessing in specs as fast as the processors.

You'll have to excuse the image quality as I took this close range with my cameraphone:
So just to put the matter to rest, Kameo has no AA. That's taken from a 45" 720p HDTV. You can see the individual pixels and that there is no edge-softening present.
Now, to stray back on topic, we have to consider in the holistic sense what this means. Personally I don't mind the fact there is no AA in RR6 or Kameo. Neither title is detrimented in gameplay experience by this and neither would be measurably 'better' with it. In the end, it's a feature which would be nice, but not something to sacrifice content for. If the greater majority of PS3 games don't feature AA, as evidenced by some test cases on the 360, I can't see it being a great loss.
i am not the aa guru..... but we had many cases where one saw zickzack edges in a picture and thought this would mean that there is no aa at work.
but then the aa gurus said that this would simply be the limit of 2aa respective 4aa and for getting rid of all edges at least 8aa or 16aa would have to be used... thats what i think is the case here
edit: meaning it would be a lot worse without AA. The cellphone picture from before.

That's a load of crap. Kameo does not look like that, I'll go home tonight and snap you a 4 mega pixel image of what it ACTUALLY looks like. None of this cell phoen camera crap, cropped down to 100px then upscaled 10x's...to twice the original resolution.Mmmkay said:You'll have to excuse the image quality as I took this close range with my cameraphone:

You're gonna pretend that this has 0AA?

" So just to put the matter to rest, Kameo has no AA."
That is so blatantly wrong it's almost sig worthy....

I can't say if Kameo has or not, but I think we should stop using gamespot's downsized pics (just checking the properties, this is 1024 whereas I would assume the original resolution needs to be 1280) to see if there is AA or not (I believe someone also tried this in another thread or something in regards to PGR3). I think the downsizing inherently causes some AA, no?

Not really sure how 2 extra megapixels are going to give you anti-aliasing that isn't there... That's a native resolution image from my 2megapixel phone camera. ALL of the information to prove that is located within the jpeg file itself. Just save the .jpg to disk and see the file properties for yourself.
Also, a nice 720p untouched framebuffer grab would be nice if you wanted to contest this opinion of mine.

That downsampled image (not 1280x720) isn't an accurate show of jaggies in game. Mmmkay's close up shows the difference between edges very clearly. More megapixels isn't going to change that, because the camera resoltuion was much greter than the pixel resolution of the display. The visible pixels aren't artefacts of the camera so you can't blame that. And in Mmmkay's shot, there certainly looked to be no AA to me.scooby_dooby said:
I just googled Kameo images and found this at the Rare website

If you downscale that to 1024x576, you get a fair smoothing of jaggies similar to the gamespot image. The linked image definitely looks to have no AA. But then you get pics like this that do. Are the jaggie pics from demo's? Or are the antialiased pics promo shots? I don't know. Almost all the pics I've looked at appear to have no AA though.

That's what some people want you to believe. It can be less noticeable, but it really depends on the situation. Even then, only Blur will help you out, and that gives you a blurry image, which is therefore less detailed than a non-blurred one.
