NVIDIA DLAA Anti-Aliasing

[maxus24]

The Elder Scrolls Online is the first game to support NVIDIA DLAA (Deep Learning Anti-Aliasing). In this mini-review, we take a closer look to compare the image quality and performance offered by DLAA and TAA anti-aliasing, and also compare the results against what DLSS can achieve.

DLAA and DLSS pretty much subdue the texture flickering and shimmering at 1080p and 1440, it's a win in my book.
Deathloop desperately need DLSS, it has sooo many flickering elements in the game.

That is called subpixel aliasing. It is significant if it can curtail artifacts not addressed by pixel based analytical filters.

 

[Xuper]

TAA has more sharper and both DLSS/DLAA has more blur. Look at pattern on the wall on right of image.

Edit : I mean 4K

 

[mtcn77]

Subpixel aliasing has been missing, but shader antialiasing has been addressed which are the main highlights that supersampling still has a reference basis.

@maxus24 thanks for sharing - interesting stuff.

Comparing these images actually shows some important differences:
Different colored spots on the tree at the wall at 1080p for example.

Of course, it will have. You should adjust LOD sharpening if you see a benefit to overall texture filtering. Funny enough, aa filters don't generate neutral balance, you can notice it from staircase artifacts(transparency antialiasing, adaa on AMD and traa on Nvidia).

I mean look at DLSS 1080.maybe developer did screw up ? DLSS quality was supposed to provide better image quality than native.

That is not possible. If you want quality, the filter should know how to interpolate. That is af by nature and analytical filters do aa, not af. Aa can be pretty intelligent though, since it has pretty rocky foundations. Essentially, all texture af formulations that finalise to pixels are actually continuous calculations, which do not actually conform the definition of discrete pixels...

PS: It can help to read the color better, but not the luminosity right. So, you have to be looking at a flawed picture to see a possible improvement. Think of it this way, flipquad was the best interpretation of aa resources, but it never got integrated into the mainstream. This is one such example where the filters are integrated.

To me it looks like another vaseline smearing AA method.

My opinion, as far as the flicker suppression of the picture is concerned, I think DLAA is the best.
Sure, it smears, but the stairs doesn´t flicker with DLAA.
Was the video 4K all the way? If yes, TAA had the stairs flickering in 4K wich is really bad.

So maybe the stairs will not flicker at lower resolution either, wich would be even greater.
Back in the days i played a lot of DX9 games with 1920x1080 4x SSAA or higher to get such degree of flicker suppression.

 

[Dristun]

Didn't look at the other parts but at 4K it's somehow blurrier than TAA (by a bit and definitely noticeable in static), and TAA was already never particularly impressive in retaining the crispness. I suppose it will help with those cases where DLSS made signs and thin lines reappear where they weren't visible in native (check GN's CP2077 video test for example) but, like, I don't see much point in losing performance for that.

 

[bogami]

I don't have the latest generation GPU. After what I see 4k it is TAA is a good support and the image is sharp as a knife until we mix DLAA exetra, where there is a visible difference in the blure effect in smaller parts, which destroys the quality. I get the feeling that someone wants to take away my beautiful and quality in-depth reliving ! yap AI real pig at work! It is not worth the money ,to ban at most, Is nothing more than quality corruption technology .

 

[ZoneDymo]

ermmm......suuuure......I cant say im in any way impressed or even notice anything of DLAA....heck my eyes might be playing tricks but I think TAA if anything looks a bit better

also the big sad thing is...again...as always, big N makes it propriatory for their products only... (and of recent generations at that) and it needs to be added by the devs soooo this can never become something big (or even lasting).
Remember when we could just force MSAA or SSAA x8 or via the gpu software and it would actually....ya know....work?
I miss those days.

 

[Manoa]

no compare to MSAA ? or SM/ML AA ?

 

[Tardian]

for users who have spare GPU headroom

I wish.

 

[Timelessest]

The difference in quality is so minimal that it seems like they are just using deep learning in order to take advantage of the deep learning hype.

 

[BArms]

TAA looks better to my eyes, and higher frame rate (what's the point of DLAA if it can't even provide a higher frame rate?)

 

[xkm1948]

Damn TAA looks like shit as always

 

[mouacyk]

needs a poll, perhaps the screens don't show the best of DLAA because TAA does look sharper

 

[Chrispy_]

TAA will always look sharper, what these side-by-side images don't show is how well DLAA deals with noise and shimmering.

At least DLAA isn't blurry like DLSS. I'm still playing NMS and that has DLSS as an "AA" option and it removes shimmering at the expense of texture clarity. 4K does not look like 4K with DLSS enabled but I'm okay with that. It's still enough detail to feel better than 1080p.

Performance impact seems high if framerates are comparable to DLSS.

@maxus24 - any chance you can give us the FPS numbers for those scenes with zero AA (as a baseline)?

The same scene that is shown on screenshots at 4K with zero AA - 144 FPS.
1080p and 1440p stays at 180FPS because of CPU bottleneck in that particular scene.

Need to see this in action on other titles with other visual styles, but it's a massively promising start imo, I find the sub 4k still DLAA's strengths start to shine through, and in motion, the strengths are in full effect. Just give us the option in all new DLSS supported games for when the performance headroom is there.

 

[The red spirit]

But can RTX 3090 run games at 1080p with 8x SSAA?

Deathloop desperately need DLSS, it has sooo many flickering elements in the game.

In my experience, the flickering and shimmering issue still exists. I've seen it in games Like Marvel Avengers and Control, and only recently. Perhaps the issue is less pronounced in newer titles that support DLSS, but the issue is very apparent to me.
