What is anti-aliasing?
To understand DLAA, you first need to know the problem that anti-aliasing solves. This section explains it with a simple picture.
Jagged edges and shimmering
Computer screens are made of square pixels. When a game draws a diagonal line, such as the edge of a roof, the pixels form tiny steps along the line, a bit like a staircase. These steps are called jaggies. When the camera moves, the steps shift and shimmer, which is distracting, especially on thin objects such as wires and fences.
Why it happens
A pixel can show only one colour. If an edge passes through the middle of a pixel, the game must decide whether the pixel belongs to the object or the background. The all-or-nothing choice creates the staircase.
What anti-aliasing does
Anti-aliasing softens those steps by blending the colours along the edge, so that the line looks smooth. Good anti-aliasing also keeps the line steady when things move.
Older methods and their limits
Games have used several methods over the years. Some draw the scene at a higher resolution and shrink it down, which looks good but costs a lot. Others blur the whole picture slightly, which is cheap but softens detail. Temporal methods use information from earlier frames, which gives smooth results but can cause ghosting. Each method trades image sharpness, stability and speed.
What is DLAA?
DLAA stands for Deep Learning Anti-Aliasing. It is NVIDIA's AI-based answer to the anti-aliasing problem.
The core idea
DLAA takes the AI model behind DLSS Super Resolution and runs it at your screen's native resolution, with no reduction in internal resolution. The game draws every pixel at full size, and the AI uses information from earlier frames and motion data to clean up edges and keep details stable. The result is a very clean, sharp picture.
Same technology, different goal
DLSS Super Resolution draws fewer pixels and rebuilds the picture to raise the frame rate. DLAA draws all the pixels and uses the AI to improve quality. In effect, DLAA is DLSS with the scale factor set to 100 percent. The DLSS 4 overview shows how the family fits together.
Why it often beats older methods
The AI model can distinguish real detail from noise and jagged edges better than a simple blur can. It tends to keep fine textures sharper while also keeping edges steady.
Which cards support it
DLAA works on all RTX cards, from the RTX 20 series to the RTX 50 series. It does not need frame generation hardware. GTX cards cannot use it, as the guide to GTX versus RTX explains.
DLAA compared with DLSS upscaling
The two are siblings with different jobs.
| Question | DLSS Super Resolution | DLAA |
|---|---|---|
| Internal resolution | Lower than native | Equal to native |
| Main goal | Higher frame rate | Higher image quality |
| Performance cost | Reduces the workload | Increases or keeps the workload |
| Best for | Needing more frames | Having frames to spare |
| Hardware | RTX cards | RTX cards |
How to read the table
DLAA is not a speed feature. It is a quality feature that you choose when your card is comfortable. DLSS Quality is the upscaling mode closest to DLAA in appearance, and it gives a speed boost at a small cost in detail. The guide to DLSS quality, balanced and performance modes shows the render scales.
A common middle path
Some players use a custom render scale between Quality and DLAA, such as 80 percent, to get most of the picture benefit at a smaller cost. The NVIDIA App's Super Resolution override can accept custom values.
When should you use DLAA?
The right situation depends on your hardware and your goals.
When it makes sense
DLAA suits powerful cards playing at 1080p or 1440p, where the card has performance to spare. It also suits older or lighter games that run far above your monitor's refresh rate. In those cases, spending the spare performance on image quality is sensible.
When it does not
If your game struggles to reach a comfortable frame rate, DLAA makes it worse. In demanding games, DLSS Quality or Balanced is a better choice. Competitive players who want the highest frame rate usually avoid it.
A check you can do
Run your game at native resolution without anti-aliasing and note the frame rate. If you are well above your monitor's refresh rate, DLAA is a good use of the spare headroom. If you are near or below it, stay with upscaling.
For high-end cards at 4K
Even powerful cards can struggle with 4K in demanding games, so DLAA is a luxury in the most demanding titles. In lighter games, it works beautifully. The site's guides to RTX 5090 at 4K and RTX 5080 at 4K show how high-end players balance quality and speed.
How to enable DLAA
There are two routes.
In the game menu
Many games list DLAA as an option beside the DLSS modes. Look in the graphics settings for DLAA, NVIDIA DLAA or a native-resolution DLSS mode. Choose it, apply and check the frame rate.
With the NVIDIA App override
If a game supports DLSS but not DLAA, the NVIDIA App's Super Resolution override can enable it. Open Graphics, then Program settings, choose the game and open Driver settings. Set the Super Resolution override to DLAA. DLSS must be switched on in the game, and you should restart the game. The guide to the NVIDIA App shows where to look.
Confirm that it works
Use the on-screen DLSS indicator to check that the render resolution equals your output resolution.
Undo it
Set the override back to the game's own setting.
How DLAA compares with other anti-aliasing methods
Several methods compete, and a table sets them side by side. The notes are general, and results vary by game.
| Method | How it works | Typical strength | Typical weakness |
|---|---|---|---|
| FXAA | Blurs edges in the finished image | Very cheap | Softens the whole picture |
| MSAA | Samples edges multiple times | Clean geometry edges | Costly, misses shader shimmer |
| TAA | Uses earlier frames | Smooth, stable | Can blur and ghost |
| DLAA | AI model with earlier frames | Sharp and stable | Needs an RTX card, costs performance |
| Supersampling | Renders at higher resolution | Excellent quality | Very expensive |
How to read the table
Each method makes a different bargain. FXAA is cheap and soft. MSAA is clean but expensive and does not handle modern effects well. TAA is common, with a reputation for blur. DLAA aims to keep the strengths of TAA's stability while keeping the picture sharp. Supersampling is the gold standard for quality and the most expensive.
Why games moved to temporal methods
Modern games use effects that older methods cannot smooth, such as shader detail and ray-traced lighting. Temporal methods handle them, and DLAA is a better temporal method.
What DLAA looks like in practice
Descriptions help you know what to look for.
Edges
Thin diagonal lines, such as wires and rails, stay smooth when the camera moves. The staircase effect disappears.
Textures
Fine texture detail, such as brick or fabric, remains sharp, whereas some older methods soften it.
Motion
Moving objects have clean outlines with fewer trails, particularly with the newer transformer models. The guide to the transformer and CNN models explains the improvement.
Shimmering
Shimmer on foliage and distant detail is reduced, though not always eliminated.
Where it can still struggle
Very fast motion, and games with poor motion data, may show some ghosting. Test in your own game, and consider a newer model if you see it.
Choosing a preset with DLAA
DLAA uses the same model families as DLSS, so presets still matter.
Which preset suits DLAA
Independent guidance has generally recommended preset K for DLAA, because the internal resolution is already full and the heavier DLSS 4.5 presets add cost with little gain. Check the NVIDIA App for what it offers. The guide to DLSS presets explains the options.
Testing it yourself
Compare presets in a scene with fine detail, and note the frame rate. If a newer preset looks cleaner and the frame rate is acceptable, keep it. If not, stay with K.
DLAA and ray tracing
Ray-traced games are expensive, and DLAA adds to the load.
Why caution is wise
A game with heavy ray tracing already pushes the card hard. DLAA on top of it may be too much. Many players use DLSS Quality or Balanced with Ray Reconstruction instead, as the guide to Ray Reconstruction explains.
When it works
On a powerful card at a lower resolution, DLAA with ray tracing can look wonderful. A card at 1080p with spare power is a good example.
Watch the temperature
A card running DLAA and ray tracing works hard. Keep an eye on temperatures and fan noise.
Four example players
These illustrations show different decisions.
The high-end card at 1440p
This player has a powerful card and a 1440p monitor. Most games run far above 100 frames, so they enable DLAA and enjoy the cleanest picture.
The mid-range card at 1080p
This player has a mid-range card at 1080p. DLAA works in lighter games, and they switch to DLSS Quality in demanding ones.
The 4K player
This player uses DLAA in older games at 4K and DLSS Balanced in the newest releases. They change per game.
The competitive player
This player avoids DLAA, because frame rate matters more than perfect edges. They use light settings and Reflex.
The lesson
DLAA is a tool for players with performance to spare, not a rule for everyone.
How much does DLAA cost in performance?
The cost depends on the game, the card and the resolution, so no single figure applies. The pattern is clear, though.
The general picture
DLAA renders every pixel at native size, so the graphics workload is as high as native resolution gets, plus the cost of the AI model. DLSS Quality renders about 44 percent of the pixels, so it runs noticeably faster. The gap between them is the price of the extra sharpness.
A way to measure it
Run a repeatable scene with DLAA, then with DLSS Quality, and note the average frame rate and the slowest frames. The difference tells you the real price on your computer.
Why the cost is higher at high resolutions
At 4K, a native frame has far more pixels than at 1080p, so DLAA costs more in absolute terms. A card that handles DLAA easily at 1080p may struggle at 4K.
Combining DLAA with a frame cap
If a game runs far above your monitor's refresh rate, a frame cap with DLAA gives a clean, quiet experience. The card works less than flat out, and the picture is as sharp as it can be.
Consider your power bill and noise
Native-resolution rendering uses more power than upscaling. If you care about quiet or about electricity, DLSS Quality is a sensible compromise.
Monitors and DLAA
The screen you use affects how much DLAA matters.
High-resolution monitors
On 1440p and 4K monitors, edges are already fine, and the benefit of DLAA is mainly in shimmer reduction and detail stability. Many players find DLSS Quality indistinguishable in normal play.
Lower-resolution monitors
On a 1080p monitor, pixels are larger and jaggies are more visible, so DLAA gives a clearer improvement. This is where it shines for powerful cards.
Large screens and televisions
On a large television viewed from a distance, edge quality still matters, but the viewing distance reduces visibility. The site's article on gaming on a 4K TV discusses the trade-offs.
Refresh rate matters too
A high refresh rate monitor wants high frame rates, and DLAA may lower them. Balance sharpness against smoothness, as the guide to high frame rates that feel rough explains.
A testing routine
Use this routine to decide whether DLAA suits a game.
Step one: baseline
Play a demanding scene at native resolution with the game's default anti-aliasing, and note the frame rate.
Step two: enable DLAA
Switch on DLAA, restart if needed and play the same scene. Note the frame rate and the picture.
Step three: compare with DLSS Quality
Switch to DLSS Quality and compare again. Look at fine detail and motion, and note the frame rate.
Step four: choose
If DLAA's picture is clearly better and the frame rate is comfortable, keep it. If you cannot tell the difference, use DLSS Quality for the extra frames.
Step five: write it down
Record the choice, and revisit when you change your card, monitor or driver.
Settings that pair well with DLAA
Companion settings can improve the result.
Sharpening
DLAA is already sharp. Turn off extra sharpening, or use it lightly, because too much creates halos.
Other anti-aliasing
Disable other anti-aliasing options in the game when you use DLAA, unless the game says otherwise. Stacking methods can blur the picture.
Motion blur and film grain
Test with these effects off to judge DLAA fairly, and add them back to taste.
Texture and shadow quality
Because DLAA is expensive, balance it by trimming heavy effects that you rarely notice, such as extreme shadow settings.
Troubleshooting
| Symptom | Likely cause | What to try |
|---|---|---|
| DLAA option missing | Game lacks it | Use the NVIDIA App override |
| Override has no effect | DLSS off in game | Enable DLSS, restart |
| Frame rate too low | Card has no spare power | Use DLSS Quality instead |
| Picture looks soft | Old model | Try a newer preset |
| Ghosting in motion | Game integration | Test other presets or modes |
| Option greyed out | Conflicting setting | Check display mode and other upscalers |
Keep notes
Write down what works for each game. The settings page in the NVIDIA App makes it easy to compare.
DLAA by game type
Different kinds of games respond differently.
Slower cinematic and story games
These games benefit greatly, because players study the picture and frame rate demands are modest. DLAA gives clean edges on detailed environments.
Strategy and simulation games
Fine lines, buildings and distant detail look cleaner with DLAA. Frame rate rarely limits these games, so there is room to spare.
Older and lighter games
DLAA is ideal for older games that run at hundreds of frames, because it turns spare performance into quality. If the game supports DLSS, it is an easy upgrade.
Fast shooters and racing games
Frame rate and delay matter more. Many players prefer DLSS Quality or lighter modes. If your card is very powerful, DLAA with Reflex can still work, but test the feel.
Open-world adventures
Large worlds with foliage and distance can be heavy. Use DLAA only if your frame rate stays comfortable.
Why DLAA exists at all
It may seem strange to offer a mode that does not raise the frame rate. The reason is simple.
Quality for those who can afford it
Some players have more graphics power than a game needs. For them, the best use of that power is image quality, and DLAA converts spare performance into a cleaner picture.
A better temporal anti-aliasing
Many games use temporal anti-aliasing, which can look soft. DLAA offers an alternative that keeps the benefits of the temporal approach while sharpening the result.
A familiar option for NVIDIA owners
DLAA uses the same software that games already integrate for DLSS, so developers can offer it with little extra work.
How it fits the family
The DLSS 4 overview places DLAA alongside the other DLSS features, and the guide to presets explains the models behind them.
What to remember when comparing with native
A common question is whether DLAA looks better than native resolution without any anti-aliasing.
Native without anti-aliasing
Native resolution with no anti-aliasing shows jagged edges and shimmering. It looks sharp in a still frame, but the motion can look rough.
Native with older anti-aliasing
This reduces jaggies but may soften the picture or cost performance.
DLAA
DLAA typically gives the cleanest result, with steady edges and sharp detail. It is the best of the options for most RTX owners who can afford the cost.
Your eyes decide
Differences vary by game and screen, so compare in the games you play.
A buyer's note: does DLAA matter for choosing a card?
If you are shopping, you might wonder whether DLAA should influence your choice.
What it tells you
DLAA works on every RTX card, so it does not favour a particular model. It does reward cards with spare performance, because only those can use it freely. A stronger card lets you use DLAA in more games and at higher resolutions.
How to think about it
Decide your resolution and refresh rate first. Then choose a card that reaches your target frame rate in the games you play, with a bit to spare. If you like the idea of DLAA, aim for a card one tier above your minimum, and you will have room for it. The RTX 50 series beginner guide and the model names guide help you place each card.
Do not overspend for one feature
DLAA is a nice option, not a reason to buy a card you do not need. A balanced setup serves you better.
A short history of anti-aliasing for the curious
The story shows why DLAA is a natural next step.
The early days
Early games had jagged edges and little to fight them. Developers drew games at higher resolution and shrank them, which worked but was costly.
The middle years
New methods blurred edges after drawing, or sampled geometry edges several times. They helped, but each had weaknesses.
The temporal era
Modern engines use information from earlier frames, which smooths almost everything, at the price of some blur and ghosting. This is where most games sit today.
The AI era
DLAA and its relatives use AI to make temporal methods sharper and steadier. It is the latest step, and it will probably keep improving.
Why this matters to you
Knowing the history helps you see that DLAA is an evolution, not a gimmick. It takes a long-standing idea and improves it with better tools.
Common mistakes with DLAA
A few errors come up repeatedly.
Expecting a speed boost
DLAA is not designed to raise frame rate. If you enable it expecting more frames, you will be disappointed.
Forgetting to turn off other anti-aliasing
Stacking methods can blur the picture. Disable extras while you judge DLAA.
Using it on a card without spare power
If the frame rate falls below your target, move to DLSS Quality or Balanced. A smooth game at slightly lower sharpness beats a choppy game at perfect sharpness.
Not restarting after an override
The NVIDIA App's override applies when the game starts, so restart after you change it.
Not checking the indicator
The on-screen DLSS indicator confirms that DLAA is active. Use it, because menus do not always reflect overrides.
A short checklist
- Confirm you have an RTX card and a current driver.
- Check the frame rate at native resolution without DLAA.
- If you have spare performance, enable DLAA in the game or through the App.
- Turn off other anti-aliasing options.
- Compare with DLSS Quality for picture and frame rate.
- Keep the setting you prefer, and note it.
Why a checklist helps
It keeps the decision simple and repeatable, so you can apply it to every new game without starting from scratch.
Review your choice with fresh eyes
After a few weeks, revisit your setting. Your eyes get used to a picture, and a quick comparison can show whether DLAA is still doing something you value. If you cannot tell the difference any more, switching to DLSS Quality gives you extra frames, lower heat and a quieter computer at no real cost in enjoyment.
A final word on enjoying the picture
It is easy to chase perfect edges, and the difference between DLAA and a good DLSS mode is small in many games. If you are happy with the picture and the frame rate, you have no need to change anything. Use DLAA when it improves a game you love, and let it go when it does not. The point of every setting in this library is to make your games more enjoyable, not to give you another thing to worry about.
Myths about DLAA
Myth: DLAA is a different technology from DLSS
It uses the same model and the same hardware. The difference is the render scale.
Myth: DLAA always looks better than native
It often looks better than native with older anti-aliasing, but it still depends on the game.
Myth: DLAA is only for RTX 50 cards
It works on all RTX cards.
Myth: DLAA raises frame rate
It does not. If anything, it lowers it. Use DLSS upscaling for speed.
Summary
DLAA applies DLSS image-quality processing at native resolution, giving smooth edges and sharp detail without upscaling. It works on all RTX cards, costs more performance than DLSS upscaling and suits situations where your card has power to spare. Enable it in a game's menu or with the NVIDIA App's Super Resolution override, check that it is active with the DLSS indicator and compare with DLSS Quality if you need frames. Use a sensible preset such as K, keep notes and revisit your choices after updates. If you are unsure which to use, test both in your favourite game, choose the one that suits your frame rate target and enjoy the result. For more on the modes that sit beside it, read the guides to DLSS quality modes and DSR and DLDSR.

Frequently asked questions about DLAA
What does DLAA stand for?
DLAA stands for Deep Learning Anti-Aliasing. It is NVIDIA's AI-based anti-aliasing technology, which uses the same model as DLSS Super Resolution but renders at your screen's native resolution. The result is cleaner edges and more stable detail, with a higher performance cost than upscaling.
Is DLAA better than DLSS?
They serve different goals. DLAA gives the best image quality because it renders at full resolution, while DLSS upscaling gives higher frame rates. If you have performance to spare, DLAA looks better. If you need frames, DLSS Quality or Balanced is the better choice.
Does DLAA work on all RTX cards?
Yes. DLAA runs on all RTX cards, from the RTX 20 series upwards, because it uses the same Tensor core hardware as DLSS Super Resolution. It does not need frame generation hardware. GTX cards cannot use it, and the game must either offer DLAA or support DLSS so that the NVIDIA App override can enable it.
Does DLAA lower FPS?
Compared with DLSS upscaling, yes, because it draws every pixel. Compared with some older anti-aliasing methods, the cost can be similar. The exact effect depends on the game and card, so test it in your own game and compare the frame rate.
Should I use DLAA at 4K?
Only if your card has headroom. In demanding games at 4K, even high-end cards may struggle with DLAA, and DLSS Quality or Balanced is more practical. In lighter or older games, DLAA at 4K looks excellent and is worth using.
How do I turn on DLAA if my game does not have it?
If the game supports DLSS, use the NVIDIA App's Super Resolution override and choose DLAA, with DLSS switched on in the game. Restart the game and check the DLSS indicator. If the game does not support DLSS at all, the override cannot add it.
