There is no universal DLSS switch that removes every trail, shimmer, or soft image. The reliable fix is to identify which DLSS feature is producing the symptom, reproduce it in a consistent scene, and change one variable at a time. Start by recording the game and patch, GPU, output resolution, driver, and enabled features. Then isolate Frame Generation, Super Resolution, Ray Reconstruction, and DLAA before deciding whether the cause is a game implementation, a driver/app interaction, or a broader rendering problem.
Start with the exact symptom and feature
“DLSS” is a group of rendering functions, not one setting. NVIDIA’s current DLSS 4.5 technology family includes Super Resolution, Frame Generation, Ray Reconstruction, and DLAA, with support varying by game and GPU generation. Each function can produce a different failure pattern, so troubleshooting them together can hide the cause.

Super Resolution
Super Resolution renders an image at a lower internal resolution and reconstructs a higher-resolution output using temporal information, motion data, and AI. Quality, Balanced, and Performance modes change the internal input resolution while leaving the display output resolution unchanged. Lower input resolution can improve frame rate but gives the reconstruction less source detail to work with.

Frame Generation
Frame Generation creates additional displayed frames from rendered frames and motion information. A generated-frame artifact can look like ghosting or unstable edges even when the underlying Super Resolution image is clean. Test Frame Generation independently rather than assuming a Super Resolution problem.

Ray Reconstruction
Ray Reconstruction replaces traditional ray-tracing denoisers. It can affect reflections, shadows, transparency, and other ray-traced detail. Flicker or trails limited to ray-traced elements should be tested with Ray Reconstruction disabled while the other DLSS settings remain fixed.
DLAA
DLAA applies AI anti-aliasing at the game’s native output resolution rather than reducing the input resolution. It can be a useful clarity comparison, but it is not a performance-upscaling mode and may cost more GPU time than Super Resolution.
Record a baseline before changing settings
A useful diagnosis needs a repeatable comparison. Write down these details and capture the same scene, preferably with the camera both still and moving:
- Game title, patch or build number, and graphics API if the game exposes it.
- GPU model and whether the system is a desktop or notebook.
- Display resolution and the game’s output resolution, refresh rate, and HDR state if relevant to the symptom.
- NVIDIA driver version and NVIDIA app version, if installed.
- Which of Super Resolution, Frame Generation, Ray Reconstruction, and DLAA is enabled, including the Super Resolution preset.
- Whether the artifact appears while standing still, only during camera movement, only on animated objects, or only in ray-traced effects.
- Whether the same scene looks normal with DLSS disabled.
Do not change resolution, preset, sharpening, Frame Generation, and a driver at the same time. A one-variable comparison is slower than flipping every switch, but it tells you which change mattered.
Fix a blurry image with DLSS on
“DLSS looks blurry” usually points to the relationship between input resolution and the game’s implementation, not to a single defective toggle. Keep the display output resolution and scene constant while making the following comparisons.
Compare Super Resolution presets at one output resolution
| Mode | NVIDIA published input-scaling example | What to expect |
|---|---|---|
| Quality | 67% of output resolution | More source detail and usually better fine detail than lower-input modes, with less performance headroom. |
| Balanced | Game-dependent; not stated as one universal percentage | A middle trade-off whose result depends on the title’s implementation. |
| Performance | 50% of output resolution | More performance potential, but less source detail for reconstruction. |
| Ultra Performance | 33% of output resolution | Designed for very demanding output resolutions; softness and instability are more likely when the game has little input detail. |
| DLAA | 100% native input resolution | Clarity reference at native resolution, with no Super Resolution upscaling. |
These percentages are NVIDIA’s published mode-scaling examples, not a promise that every game exposes every mode or uses identical reconstruction behavior. Some compatible titles expose presets or custom input scaling through the NVIDIA app; the available controls depend on the game and driver.
Use native rendering or the game’s alternative anti-aliasing as a control
Disable DLSS and choose native resolution or the game’s built-in alternative anti-aliasing/upscaler. Compare the same camera angle and HUD elements. If native rendering is sharp but every DLSS mode is soft, the result is likely specific to that title’s implementation, input resolution, or temporal data. If native rendering is also soft, inspect the game’s resolution scale, display mode, texture settings, and operating-system scaling instead of blaming DLSS alone.

Check the input resolution, not just the monitor resolution
A 4K monitor does not guarantee a 4K reconstruction input. Performance modes may render internally at a much lower resolution, and a game can apply an additional resolution scale before DLSS receives the image. Set any separate render-scale control to its documented default while comparing presets. Do not infer a universal best mode: Quality can look excellent in one title and still show unstable detail in another.
Judge detail in motion as well as in a screenshot
Inspect thin geometry, foliage, fences, hair, text, and distant specular highlights while panning the camera. A still screenshot can hide temporal instability, while motion can make a reconstruction look softer or reveal trails. Record both states before selecting the mode that fits your game and display.

Fix DLSS ghosting and trails
Ghosting is a repeated or delayed image behind a moving object, camera, or effect. DLSS uses previous frames and motion data, so the game’s motion vectors, disocclusion handling, and temporal implementation affect the result. Frame Generation can add a separate source of trails.
First separate Frame Generation from Super Resolution
- Keep your current Super Resolution preset unchanged.
- Turn off Frame Generation in the game.
- Reproduce the same moving-object or camera-pan scene.
- Turn Frame Generation back on and compare without changing any other setting.
If the trail appears only with Frame Generation, report it as a Frame Generation or title-specific artifact rather than changing the Super Resolution preset. If it remains with Frame Generation off, continue testing Super Resolution and, where applicable, Ray Reconstruction.

Use a moving character crossing a static background, a fast camera turn, and an object emerging from behind cover. Trails that follow one character but not the environment can indicate title-specific motion-vector or disocclusion handling. A smear that follows the entire image during camera movement may instead be caused by a display response setting, motion blur, or another post-process effect. Disable the game’s motion-blur option only for the comparison, then restore it if it is not responsible.
Compare Quality and native rendering at the same scene
Run the scene with DLSS Quality, then with DLSS disabled at native resolution or the game’s alternative anti-aliasing. If the trail disappears only in the native comparison, capture the settings and scene for the developer. A single game showing ghosting does not establish a GPU hardware defect.
Fix DLSS flickering, shimmering, and unstable fine detail
Flickering can appear as alternating brightness, crawling foliage, sparkling reflections, or edges that change shape between frames. Temporal reconstruction, ray-traced denoising, Frame Generation, and the game’s own shaders can all contribute.
Identify what is flickering
- Only ray-traced reflections, shadows, or transparencies: disable Ray Reconstruction while leaving Super Resolution fixed.
- Thin geometry such as wires, foliage, or fences: compare Quality with native rendering and check whether the object is affected only during motion.
- The whole image or UI-adjacent areas: test Frame Generation separately and verify that no separate frame-interpolation feature is active.
- Only one game or one level: treat it as an implementation or content issue until another title reproduces it.
Change one temporal feature at a time
Do not switch Super Resolution, Ray Reconstruction, Frame Generation, and an anti-aliasing option in one pass. Keep the output resolution fixed, disable one feature, and replay the same camera path. Note whether the flicker is reduced, unchanged, or moved to a different object. This produces evidence a developer can reproduce.
Do not combine native Frame Generation with NVIDIA Smooth Motion
NVIDIA’s driver guide warns that native DLSS Frame Generation and NVIDIA Smooth Motion compete with each other and can cause lower performance and visual artifacts. That guidance appears in the guide’s Linux-oriented documentation context; platform and compatibility-layer behavior can differ. If both options are present, disable Smooth Motion while testing the game’s native Frame Generation, then test the reverse combination only if your platform supports it and the game documentation calls for it.
Check game, driver, and app versions carefully
Update the game first when a patch is available
DLSS behavior is tied to the title’s engine integration and update level. Check the game’s patch notes or launcher for an update, then repeat the same scene comparison. A patch can change motion vectors, presets, supported features, or the way the game exposes DLSS controls.
Verify the current NVIDIA driver listing
The NVIDIA listing consulted for this guide showed GeForce Game Ready Driver 617.14, released September 22, 2026. Driver releases change, so verify the live NVIDIA driver page rather than treating that version as permanently current. Install the driver appropriate to your operating system and GPU, and record the version used for your test.

Notebook owners should follow the OEM’s guidance
NVIDIA recommends that notebook owners check their notebook manufacturer for recommended driver updates. A generic desktop package may not be the validated choice for a particular notebook, hybrid-graphics design, or display path. If a problem began after a driver change, document the versions and consult the OEM and NVIDIA support guidance; do not treat a rollback as a universal fix.

Do not replace DLSS files as a first-line fix
Unofficial DLL swaps and configuration edits can break game updates, anti-cheat checks, or feature compatibility and make the original cause harder to identify. Use the game’s documented controls and supported NVIDIA app options while diagnosing. Escalate with reproducible evidence before attempting any unsupported file replacement.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Linux, Proton, and compatibility-layer checks
Linux and Proton users have an additional compatibility variable. Record the distribution, kernel or driver package source, Proton version, translation layer, launch options, and whether the game uses native Frame Generation or a driver-level feature. Reproduce the issue with one configuration, then compare only the feature you are isolating. A result that occurs only through a compatibility layer should be reported with that layer and version; it should not be generalized to the Windows implementation.
Decide whether DLSS is the cause
Use this decision path after your comparisons:
- The artifact appears with DLSS disabled too: investigate the game’s anti-aliasing, motion blur, resolution scale, ray-tracing settings, display response, and other post-processing.
- Only Super Resolution changes the artifact: compare Quality, Balanced, Performance, and native rendering at the same output resolution, then report the title and preset that reproduce it.
- Only Frame Generation changes the artifact: keep Super Resolution fixed and report Frame Generation separately, including any Smooth Motion setting.
- Only Ray Reconstruction changes the artifact: identify the affected ray-traced element and report that feature independently.
- Only one game reproduces it: treat it as likely title- or feature-specific, not proof of failing hardware.
- Several games reproduce it in the same way: compare drivers, operating-system settings, display behavior, and GPU stability, then contact NVIDIA or system support with the complete record.
What to send when you escalate
A useful support report is more than “DLSS is blurry.” Include:
- Game name, patch/build, platform, and graphics API.
- GPU model, notebook model when applicable, operating system, and driver version.
- Display and output resolution, refresh rate, HDR state, and any compatibility layer.
- Exact DLSS features and modes: Super Resolution preset or custom scale, Frame Generation, Ray Reconstruction, and DLAA.
- Whether NVIDIA Smooth Motion or another frame-interpolation option is enabled.
- The repeatable scene, camera movement, and whether the symptom occurs while stationary.
- A comparison with DLSS disabled and the result of each one-variable test.
- Short clips or screenshots that show the same frame or camera path under each configuration.
This information lets the game developer or NVIDIA support distinguish an implementation issue from a driver, display, or system problem.
Performance and image-quality trade-offs
Lower Super Resolution input modes can raise performance because fewer source pixels are rendered, but they reduce the detail available for reconstruction. Native rendering and DLAA preserve native input detail but can require more GPU time. Frame Generation can increase displayed frame rate while introducing its own latency and artifact considerations, so judge it separately from the base rendered image. The right choice depends on the game, output resolution, GPU, motion in the scene, and your tolerance for softness or temporal instability.
NVIDIA has published historical game-specific performance claims, such as up to 40% improvement for Battlefield V at 4K and 2560×1440 in 2019. That figure is not a general promise for current games or hardware and should not be used to predict the result of your troubleshooting changes.
When the best fix is to leave DLSS off
If native rendering or the game’s alternative anti-aliasing is consistently clearer and fast enough for your target frame rate, leaving DLSS disabled is a valid outcome. DLSS quality varies with resolution, graphics settings, motion data, and the game’s implementation. The goal is a stable, readable image at acceptable performance—not enabling a feature when its artifacts remain unacceptable in a particular title.
