NVIDIA Finds a Clever Way to Boost DLAA Adoption—To Turn it into a DLSS Preset

[btarunr]

DLAA, or deep-learning anti-aliasing, is essentially DLSS without the image upscaling. The technology holds the rendering resolution at par with your display's, but uses AI to attempt to add detail to your game, particularly smoothing out edges and other forms in the raster graphics that could require anti-aliasing. The result is image quality that's visibly superior to even native-resolution, and other methods of anti-aliasing, such as TAA and MSAA. Since all this is happening at native resolution, there is zero performance gain, some performance loss, however not one that is comparable to MSAA. It's a wonderful technology, and any game that supports DLSS should naturally expose DLAA in its quality settings to end-users, however this isn't the case. DLAA is seeing sluggish adoption among game developers, and NVIDIA has taken it upon itself to fix this.

NVIDIA is working on updates to DLSS that essentially makes DLAA a quality preset. We know from an article from earlier this week that DLSS performance presets don't just linearly scale render resolution, but affect other algorithm features, such as Reflex. A unique "G" preset was found in an Unreal Engine 5.2 presentation by Epic. It turns out, that this preset is part of the updates NVIDIA is planning for not just DLSS 3, but also DLSS 2, which makes DLAA a quality preset for DLSS. When engaged, it renders the game at 100% display resolution, without upscaling, but applies much of the AI image reconstruction features of DLSS. With this, it is hoped that many more game developers will pick up on DLAA, and integrate it with practically any game that supports DLSS.

There is a tweak to apply DLAA in games that come with DLSS SR 3.1, I guess this update just make it easier, quite a welcomed update to DLSS

For the couple of games I've used with DLAA it's definitely the best AA option and I wouldn't hesitate to use it.

DLSS is a crutch that hurts image quality more than it helps, IMO. I used DLSS sometimes to get 4K60 running smoothly but in just about every possible scenario I found it better to just lower the graphics settings so that I could run native. Raytracing with DLSS is noisy, shimmery, and has dramatically worse lag on reflections and RT occlusion/shadows. It's bad enough that I notice all the things "wrong" with DLSS far more than I appreciate the higher resolution. YMMV of course, but I can handle slightly lower resolution with ease - sometimes it's as easy as just sitting back a bit further on the sofa. I cannot handle all kinds of smear/lag/shadow-fade-in/wobbly delayed reflections at any viewing distance.

It really is unmatched, the only game I currently play that supports it is Deep Rock Galactic, but then I only really play 3-4 games regularly these days.

I wonder how many people in the poll are confusing it with DLSS, since in my experience it's better than native 100% of the time. Maybe there's some mild artifacts, but I've never noticed them, and the improvement in anti-aliasing is borderline perfect - looks like a much higher resolution image.

It is a shame to see that so many games which support DLSS don't have a DLAA option currently, hopefully that changes with this and other improvements NVIDIA is making.

Try using DLSS with DLDSR, it's basically free performance at no hit to IQ, or better IQ.

Messed up sentence: "that supports DLSS should expose naturally expose DLAA in its quality settings"

Most of the time I rather just have native resolution with a good AA options, or essentially SSAA. If I do need to run DLSS/FSR to get just a few more frames, I might like it better if there was an even higher quality setting that ran at like 1800p or something. I generally rather just have it turned off with some settings tweaked lower. Really only use DLSS/FSR when I have RT enabled.

DLDSR is your higher quality setting.

Its technology and tricks like this that cause people to use Nvidia over its competitors. I would really like to see the benefit of this in person or maybe TPU can show us a few comparison slides. Anything that helps AA is a win for me!

Does this mean there's a way to turn on DLAA on Modern warfare 2:warzone even though its not an option in the in-game menu?

Look at any of the DLSS game articles, there's a DLAA option in the comparison screenshots.

Ooooohhhh, thx for the info.

***A few moments later***

DLAA is actually pretty damn decent in some cases. I couldn't see a difference in Cyberpunk. But in a few other games, its actually pretty impressive.

 

[chrcoluk]

In Nvidia sponsored titles might we see DLAA as the only AA option?

 

[GeForce_JacobF]

Diablo IV has DLAA support and it is a great option for higher end hardware as it generally runs at very high FPS.

 

[GreiverBlade]

For me, @ 1620p and above: noAA = best AA...

 

[Sithaer]

Yup, I'm also playing D4 and DLAA is pretty much the best AA option in the game currently with an Nvidia card.

I agree with everything you just said! I've also tried DLAA in only a few games, but every time it's been absolutely something I want to turn on. I'm very glad to see it getting pushed. I've also the same opinions of DLSS; i.e. I'd rather lower quality settings than play with DLSS on, every time.

 

[Chrispy_]

I'd rather lower quality settings than play with DLSS on, every time.

I think I can liken DLSS upscaling to playing on a really slow, smeary LCD panel. It looks great when things are static but the moving image is obviously worse and it's not even uniformly worse so your eye is drawn to the bits that look wrong far more easily.

I've been working through the PS5 ports this year - God of War, Horizon Zero Dawn, Uncharted 4 etc - and they all support DLSS and they're all third-person so whenever you turn the camera (which is just about all the time) you get this horrific shimmering down the trailing edge of the player character front and center of your experience. That would be bad enough but then all three games also suffer from the repeating artifact issue where that trailing edge shimmer is then stamped and repeated into the background. It honestly doesn't matter what the resolution is, I'd rather play at 720p native than 4K with DLSS image issues.

All three of those named games look FANTASTIC with DLSS in static screenshots but the human eye (technically the visual cortex) is incredible at picking out patterns in motion - and not by coincidence either, it's an evolutionary trait in most animals to spot camouflaged prey/predators because those that couldn't starved or were eaten, respectively. The number of games that look really good with DLSS is tiny, and most of those are the highest-profile AAA games where Nvidia has made a special effort to get involved at the developer level (eg, CP2077). Even then, it's taken several iterations to work around the inherent artifacts that come from upscaling so it's still not an absolute win vs native resolution.

I've never found it to be worse than native + TAA, makes me think a lot of votes are coming, yet again, from people who don't use it.

I wonder how many people in the poll are confusing it with DLSS, since in my experience it's better than native 100% of the time. Maybe there's some mild artifacts, but I've never noticed them, and the improvement in anti-aliasing is borderline perfect - looks like a much higher resolution image.

Perhaps that too, DLSS Q at 4k almost always looks as good or better, and is extremely rarely worse in any discerable way, plus the AA resolve is straight up unmatched. Again, hard to believe anyone who'd actually seen it with their own eyes would argue native TAA is better (than DLAA).

It is a shame to see that so many games which support DLSS don't have a DLAA option currently, hopefully that changes with this and other improvements NVIDIA is making.

100% welcome the option in every single game.

 

[Chrispy_]

DLAA is native + TAA.

So yeah, it can't possibly look worse than native + TAA because that's the starting point for DLAA and no upscaling means no pixel-guesswork artifacts. It's literally all the good bits of DLSS with none of the bad bits.

Yes I understand what DLAA is, native input resolution plus the AA pass from DLAA/DLSS, which is why I'm also confounded that anyone could vote saying no it's not better than native.

The AA in DLAA/DLSS is the best TAA derivative in the business, hands down, no question about it imo.

 

[Chrispy_]

In that poll, "No" does not mean that 57% of people think native is better than DLAA. That would be true only if the poll was re-worded to a binary choice of "Which is better, DLAA or Native?"

DLAA really shines when you have sub-pixel lines (such as cables in the distance, wire-link fences etc), or very slightly off-angled geometry that's half a degree off the horizontal or vertical pixel grid. If the game doesn't have an art style that trips up TAA then it seems fair to me to call TAA comparable. Not all games need DLAA to pull off near-perfect AA quality.

As good as DLAA is, it's not free; It has one of the highest performance overheads of any AA method outside of the long-obsolete MSAA and in that poll, "better" is subjective - based on the games a person plays, whether they interpret the word "better" considering the performance cost or just looking at image quality alone, and doesn't give you any idea how many of those "no" respondents were on the fence, given that the wording of the question is "always". I can definitely imagine there are games I haven't played where DLAA has little benefit but still adds the performance penalty, even though all the DLAA games I've played look better with DLAA!

 

[wolf]

As good as DLAA is, it's not free; It has one of the highest performance overheads of any AA method outside of the long-obsolete MSAA and in that poll "better" is subjective for those that feel the question is about the quality/FPS balance, rather than just looking at the image quality in isolation.

Makes sense and good insights, however I'd bet money on some of the voters don't on the requisite hardware to test that for themselves.

In the end, the poll is very vague and leaves lots of room for how you want to interpret the term 'better' and the multiple ways in which that could be true.

 

[HOkay]

It's a fairly small overhead still though, somewhere in the 8-10% kind of range vs native. It'll depend on your GPU, the target resolution & refresh rate, the game etc. but most of the time for me it's definitely worth that.

Ooooo. Let me guess
