For most games, anti-aliasing should be on—but the best setting is the one that removes distracting jagged edges and shimmer without adding excessive blur or lowering performance below your target frame rate. If you need more FPS, lower or disable AA after testing the game in motion; if the game offers several methods, choose based on the method rather than the simple “on” label.

Anti-aliasing (AA) smooths stair-step edges that appear when a game has to represent diagonal lines, curves, thin geometry, or subpixel details with a finite grid of pixels. It can make fences, wires, foliage, character silhouettes, and building edges look cleaner. The trade-off is that some methods consume GPU resources, and some can soften the image or create ghosting during movement. NVIDIA describes the general choice as a balance between system performance and improved image quality (NVIDIA’s anti-aliasing guide).

What anti-aliasing does
A diagonal line cannot always pass cleanly through individual square pixels. Without anti-aliasing, pixels along the edge are usually drawn as either the object’s color or the background color. The result is a visible staircase, commonly called a jaggy.

Anti-aliasing estimates how much of each edge pixel should be covered by the object and blends the edge with nearby colors. The result is a smoother-looking boundary rather than a sequence of abrupt steps. This does not increase the physical resolution of your monitor, and it cannot recover detail that was never rendered. It changes how the available pixels are used.
That smoothing can have costs:
- Performance: Some methods require additional samples, higher internal resolution, or substantial temporal processing.
- Softness: Post-process methods can blur textures, small details, the HUD, or text.
- Temporal artifacts: Methods that use previous frames can produce ghosting, trails, crawling detail, or instability when objects move.
- Incomplete coverage: One method may smooth polygon edges while leaving transparent foliage, particles, shadows, reflections, or shader effects aliased.
Should anti-aliasing be on or off?
| What you see or need | Recommended starting point |
|---|---|
| Jagged edges and shimmering are distracting, and performance is comfortable | Leave AA on and test the game’s available methods. |
| You need more FPS or lower latency | Reduce the AA quality or choose a lighter method before disabling every other quality setting. |
| The image is excessively soft | Try a sharper AA method, increase render resolution, or disable the game’s post-process AA and inspect motion—not just screenshots. |
| Foliage, wires, fences, or particles still shimmer | Try temporal AA, transparency AA, a higher internal resolution, or the game’s reconstruction option. Ordinary MSAA may not address these effects. |
| You are playing an older game with a conventional forward renderer | MSAA can be a good choice if the game supports it and the performance cost is acceptable. |
| You are unsure what NVIDIA driver settings to use | Use Application-controlled and configure AA inside the game. |
Turning AA off can improve performance and may make a still image look sharper, especially if the game’s post-process AA is soft. It also exposes more jagged geometry, transparency aliasing, and shimmer during motion. Therefore, compare settings while panning the camera, walking past foliage, and viewing thin lines—not only in a paused screenshot.
Likewise, a higher number is not automatically better. NVIDIA notes that 16x represents a higher quality level than 2x, but the practical result depends on the game and its implementation. A high sample count may cost more while failing to solve temporal shimmer or screen-space artifacts.
Common anti-aliasing types
FXAA: fast and inexpensive, but often soft
FXAA means Fast Approximate Anti-Aliasing. It is a screen-space, post-process filter: it examines the finished frame and looks for likely high-contrast edges, then smooths them. NVIDIA describes FXAA as improving image quality with less performance impact than other AA settings and as useful for applications without hardware-based AA (NVIDIA Control Panel reference).
FXAA is a sensible option when your GPU is limited or you want a quick reduction in obvious jaggies. Its weaknesses are equally important:
- It can soften textures and fine geometry because it cannot always distinguish an actual edge from detail that should remain sharp.
- It may not resolve every form of aliasing, particularly details that are difficult to identify from the final frame.
- A driver-level FXAA filter can affect the whole frame. Depending on where the game renders its HUD and where the driver applies the filter, menus and text may also become soft.
Choose FXAA when performance matters more than maximum clarity. If the result looks blurry, try the game’s other AA options or disable FXAA and compare at native resolution.
MSAA: clean polygon edges at a higher cost
MSAA, or Multisample Anti-Aliasing, samples coverage at polygon edges. It is especially effective at smoothing traditional geometric boundaries such as the outline of a building or character. It is not a complete solution for every effect: alpha-tested foliage, fences, particles, shader aliasing, shadows, and other screen-space details may remain jagged. The Valve Developer Community’s MSAA documentation describes these strengths and limitations.
MSAA can become expensive at higher sample counts. It is also less commonly the only AA option in modern deferred-rendering games, where temporal or reconstruction-based techniques often cover more of the final image. If a game offers 2x, 4x, or 8x MSAA, higher values can improve polygon edges but should be tested against your frame-rate and frame-time target.

NVIDIA MFAA with MSAA
On compatible NVIDIA systems, Multi-Frame Sampled AA (MFAA) can work with games that expose 2x or 4x MSAA. NVIDIA’s documented setup is:
- Right-click the Windows desktop and open NVIDIA Control Panel.
- Open Manage 3D Settings.
- Set Multi-Frame Sampled AA (MFAA) to On.
- Click Apply.
- Set the game’s anti-aliasing option to 2x MSAA or 4x MSAA.
MFAA is not universal. NVIDIA specifically lists Dead Rising, Dragon Age 2, and Max Payne 3 as incompatible examples (NVIDIA MFAA support). If there is no visible improvement, artifacts appear, or performance changes unexpectedly, return MFAA to Off and use the game’s native setting.
TAA: broad coverage and better motion stability
TAA, or Temporal Anti-Aliasing, uses information from multiple frames. Because it can accumulate samples over time, it can address both ordinary geometric aliasing and temporal shimmer. This makes it particularly useful for modern games with deferred rendering, foliage, thin geometry, shadows, reflections, and other screen-space effects. A technical overview is available in the Temporal Anti-Aliasing reference.
Do these 3 things before closing this tab:
1Clear out junk files and repair common Windows errors2Fix the driver behind crashes, sound loss and screen glitches3Repair Windows errors before they cause bigger problemsThe trade-off is that TAA depends on accurate motion vectors and a usable history of previous frames. Fast movement, disocclusion—when a previously hidden surface becomes visible—and imperfect reconstruction can cause:
- ghost trails behind moving objects;
- soft or smeared fine detail;
- crawling or unstable textures;
- temporary artifacts around particles, foliage, wires, and reflections.
Disabling TAA may produce a sharper paused image, but foliage, wires, shadows, reflections, and subpixel geometry can shimmer much more while playing. If a game has a TAA sharpening slider, use it cautiously: sharpening can restore perceived crispness but cannot fix incorrect motion history or eliminate all ghosting.
SSAA and supersampling: excellent quality, heavy rendering cost
SSAA, or Supersample Anti-Aliasing, renders the scene at a higher internal resolution and downsamples it to the display resolution. Rendering more pixels generally produces high-quality smoothing, but it can be one of the most expensive options because the GPU must process substantially more image data.
Supersampling is most practical when your GPU has considerable performance headroom, or in an older or less demanding game. NVIDIA’s Control Panel also distinguishes transparency Multisampling, which favors performance, from transparency Supersampling, which favors quality (NVIDIA’s settings reference).
DLSS, DLAA, FSR, and XeSS: reconstruction and anti-aliasing are related but not identical
Modern games may put anti-aliasing inside an upscaling or reconstruction pipeline. That does not make every option interchangeable.

- DLAA uses NVIDIA DLSS technology for anti-aliasing at native resolution. It is not the same as DLSS Super Resolution.
- DLSS Super Resolution renders internally at a lower resolution and reconstructs a higher-resolution output, usually to improve performance. Its anti-aliasing behavior is part of that reconstruction process.
- Frame Generation creates additional displayed frames; it is not itself an anti-aliasing method.
- Ray Reconstruction addresses an element of ray-traced image reconstruction; it should not be treated as a general AA toggle.
- FSR and XeSS are vendor technologies whose available modes and image quality depend on the game’s implementation. Their presence does not mean the same AA choices are available in every title.
NVIDIA’s documentation emphasizes that DLSS features are game-specific. A title may provide DLSS Super Resolution, DLAA, Frame Generation, or Ray Reconstruction independently, and “DLSS on” does not necessarily mean the game is rendering at native resolution (NVIDIA gaming and DLSS documentation).
NVIDIA App DLSS overrides
For games that already have DLSS Super Resolution enabled but do not natively expose certain modes, the NVIDIA App can provide DLAA & Ultra Performance Modes through DLSS Override – Super Resolution. The documented path is:
- Open the NVIDIA App and go to Graphics > Program settings.
- Select the game.
- Scroll to Driver Settings.
- Choose DLSS Override – Super Resolution.
- Select the desired mode, click Apply, and reopen the game.
NVIDIA’s support article, updated February 3, 2025, lists Game Ready Driver 572.16 or newer and NVIDIA App 11.0.2.312 or newer as minimums for the documented DLSS 4 overrides (NVIDIA DLSS override instructions). To return control to the game, select Use the 3D application setting.

- Start with the game’s own AA control. It usually knows which method is compatible with that game’s renderer and post-processing pipeline.
- Set a realistic performance target. Check the frame rate and frame-time consistency in a demanding scene, not only in a quiet menu or opening area.
- Inspect motion. Pan the camera across fences, foliage, wires, rooftops, and distant detail. Look for jaggies, shimmer, ghosting, and softness.
- Try methods in a sensible order. Compare TAA or a reconstruction method against FXAA, then test MSAA where the game supports it. Use supersampling only when the GPU has room.
- Change one setting at a time. Otherwise you cannot tell whether a change in sharpness or performance came from AA, resolution scaling, sharpening, texture quality, or another option.
- Keep the setting that looks best during play. A technically sharper screenshot is not automatically a better gaming image if it shimmers constantly.
At lower resolutions, jaggies are usually more visible, so AA can be more valuable. At higher resolutions, the improvement may be subtler, but thin geometry and temporal shimmer can still benefit from an effective method. Display resolution, internal render resolution, camera movement, game engine, and the type of content on screen all affect the result.
NVIDIA Control Panel: the correct paths and modes
To configure NVIDIA driver settings globally or for one game, right-click the Windows desktop, open NVIDIA Control Panel, select Manage 3D Settings, and choose either Global Settings or Program Settings. Program Settings is safer for testing because it avoids changing every game.
The relevant controls are:
- Antialiasing – Mode
- Antialiasing – Setting
- Antialiasing – FXAA
- Antialiasing – Gamma correction
- Antialiasing – Transparency
- Multi-Frame Sampled AA (MFAA)
Antialiasing – Mode includes four important choices:
| Mode | When to use it |
|---|---|
| Off | Disables the driver’s AA mode. Use when troubleshooting or when the game’s own renderer should receive no driver AA. |
| Application-controlled | The preferred default when the game has its own AA controls. NVIDIA recommends this mode when you are unsure how to configure driver AA. |
| Enhance the application setting | Adds driver AA to an AA level already selected in the game. NVIDIA says the game must have an AA level selected—for example, 2x—before this option can add to it. |
| Override any application setting | Designed for applications without built-in AA controls or situations where built-in AA fails with HDR. It is not a guarantee that modern games or every rendering API will respond. |
On GeForce 8 Series and later, Antialiasing – Setting is read-only when Antialiasing – Mode is Application-controlled or Off. That behavior is expected; change the mode first if the driver permits it.
Transparency anti-aliasing is a separate problem
Ordinary polygon-edge AA may not smooth alpha-tested or partially transparent surfaces. This is why foliage, hair, chain-link fences, grates, and thin leaves can remain jagged even with MSAA enabled. NVIDIA exposes this separately as Antialiasing – Transparency.

The choices typically favor either performance through multisampling or quality through supersampling. Available sample values are constrained by the ordinary AA level. For example, NVIDIA states that with 4x AA selected, transparency values may include 1x, 2x, and 4x, but not 8x.
Why a driver override may do nothing—or make the image worse
NVIDIA Control Panel options are application-, API-, GPU-, and rendering-path-dependent. A setting can be visible in the panel without being able to force a meaningful change in a particular modern game. Newer engines may use deferred rendering, temporal reconstruction, HDR paths, or APIs that do not respond to legacy driver overrides.
Forcing AA can also conflict with the game’s own method. Common symptoms include:
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
- no visible change;
- double-processing and excessive blur;
- shimmering that was not present before;
- broken transparency or lighting;
- rendering artifacts, crashes, or an option that silently resets.
If a driver override fails, set Antialiasing – Mode back to Application-controlled, restart the game, and use the in-game option. If you changed the preferred GPU in NVIDIA settings, restart the program as well: changing Preferred graphics processor does not affect a game that is already running (NVIDIA Control Panel reference).

A practical troubleshooting checklist
The game looks jagged
- Confirm that AA is enabled in the game rather than only in the driver.
- Try TAA or a reconstruction option if the jaggies move or shimmer.
- Increase internal resolution or render scale if performance allows.
- For an older game, test 2x or 4x MSAA.
- Check transparency AA if the problem is mostly foliage, fences, grates, or hair.
The game looks blurry
- Test FXAA against the game’s other options; FXAA commonly trades detail for low cost.
- Compare TAA while moving, since a still image can make its softness appear worse or better than it feels in play.
- Check whether resolution scaling is below 100%.
- Try DLAA at native resolution if the game supports it and your GPU can maintain the desired frame rate.
- Disable driver-level FXAA if it may be filtering the HUD or text.
The game shimmers during movement
- Disabling AA is unlikely to solve the underlying problem; it often makes temporal shimmer more obvious.
- Test TAA, DLSS Super Resolution, FSR, or XeSS, depending on what the game provides.
- Inspect foliage, wires, shadows, reflections, and distant geometry separately.
- Use a higher render scale if reconstruction artifacts remain and performance permits.
The NVIDIA setting has no effect
- Move the profile from Global Settings to Program Settings for the correct game executable.
- Use Application-controlled unless the game lacks a working AA option.
- Do not assume a modern rendering API accepts a legacy driver override.
- Restart the game after changing the preferred GPU or DLSS override.
- Undo the override if it causes blur, artifacts, or instability.
The short recommendation
Use the game’s built-in anti-aliasing first. Keep it enabled if jagged edges or shimmer are visible and you have enough performance headroom. Prefer a method that remains stable during movement: TAA or a reconstruction-based option is often more comprehensive in modern games, while MSAA can be excellent for geometric edges in compatible older titles. FXAA is a useful low-cost fallback but may be soft. SSAA provides very good quality when you can afford its heavy pixel workload.
Turn AA down or off only when the performance gain is worthwhile, and judge the result while playing rather than from a static screenshot. For NVIDIA driver settings, leave Antialiasing – Mode on Application-controlled unless you have a specific compatibility reason to enhance or override the game.
Frequently Asked Questions
What does anti-aliasing do?
Anti-aliasing smooths stair-step edges by blending pixels along object boundaries. Depending on the method, it can also reduce shimmer and improve thin geometry, but it may cost performance or make the image softer.
Should anti-aliasing be on or off for gaming?
Usually, yes. Leave it on when jagged edges or shimmering are distracting and your GPU has enough headroom. Turn it down or off when you need the performance and can accept more aliasing.
Is higher anti-aliasing always better?
Not necessarily. FXAA is a lightweight screen-space filter, MSAA targets polygon coverage, TAA uses information from multiple frames, and DLAA applies DLSS technology at native resolution. Their sharpness, coverage, artifacts, and performance costs differ.
How do I fix blurry anti-aliasing?
Try a sharper or less aggressive method, check that resolution scaling is at the intended value, and disable any driver-level FXAA that may be filtering the whole frame. Also compare the image while moving, because TAA softness and ghosting can look different in motion.

The Bottom Line
Bottom line: Anti-aliasing is usually worth leaving on, but “on” is not a quality level. Start with the game’s own setting, compare the actual method in motion, and lower or disable it only when blur or performance loss outweighs the reduction in jaggies and shimmer.
