To troubleshoot DLSS artifacts, first identify which feature is active—Super Resolution, Ray Reconstruction, or Frame Generation—then compare the game with that feature off and back on while keeping other settings constant. If an artifact appears only in one title and persists through those checks, its cause may lie in the game’s rendering integration, not a setting you can repair yourself.
Identify the DLSS feature before changing settings
DLSS is a group of features, not a single image-quality toggle. NVIDIA’s DLSS overview lists Super Resolution and Ray Reconstruction for GeForce RTX 20 through 50 Series, while standard Frame Generation support is listed for RTX 40 and 50 Series. Check compatibility for the specific feature and game; support for one DLSS feature does not mean every feature is available on every GPU.

- Super Resolution renders the game at a lower input resolution and upscales the image. Soft fine detail may be associated with its selected mode or scaling.
- Ray Reconstruction reconstructs ray-traced or path-traced effects and replaces traditional hand-tuned denoisers in supported implementations.
- Frame Generation synthesizes additional frames. It can affect moving objects and interface elements differently from the underlying rendered frames.
Before testing, note the game, GPU, driver and NVIDIA app versions, display resolution, active DLSS component and mode or preset, and whether Ray Reconstruction or Frame Generation is enabled. This record helps make a later report reproducible; it does not establish the cause by itself.

- In the game’s graphics settings, note the current resolution and DLSS options. Record whether Super Resolution, Ray Reconstruction, Frame Generation, and motion blur are enabled.
- Disable the feature most closely associated with the symptom, then compare the same scene. Keep resolution and other graphics settings unchanged so you are not comparing several variables at once.
- Re-enable the feature and, if practical, test only one DLSS component at a time. For example, compare Super Resolution alone with Super Resolution plus Ray Reconstruction, or compare Frame Generation on and off.
- Repeat the comparison in the same scene and during the same kind of movement. A short clip can help show whether the artifact appears consistently.
This is a diagnostic check, not a recommendation to leave DLSS disabled. Disabling a feature can change image quality or performance, and the preferred balance depends on the game and system.

Fix soft or blurry fine detail
Compare Super Resolution modes
If small details look soft, compare the Super Resolution modes the game supports. A higher input resolution may preserve more detail, but it can reduce performance headroom. Judge the visual and performance trade-off in the same scene rather than assuming one mode is best for every game.
Check NVIDIA app options where available
NVIDIA documents per-game DLSS model overrides and Super Resolution scaling customization in its app. Availability and labels depend on the title, in-game setting, app and driver versions, and hardware, so there is no universal menu path or guaranteed improvement. Change one supported option at a time and compare it with the game’s original setting.

Check Ray Reconstruction in ray-traced games
For a soft or smudged image in a ray-traced or path-traced game, compare the title’s Ray Reconstruction setting, if offered, and any supported NVIDIA app model selection. Results depend on the game’s implementation; a setting change is a test, not a guaranteed cure.

Diagnose flickering
First check whether flickering occurs with Super Resolution alone or only after enabling Ray Reconstruction or Frame Generation. This helps narrow down which component is involved, but does not prove the root cause.
Rank #3
- Smooth motion: 240Hz refresh rate and fast 0.5ms response time provide crisp visuals and fluid movement with less input lag.
- Seamless gaming: FreeSync Premium and HDMI VRR eliminate tearing for smooth, responsive PC and console gameplay.
- Fast IPS: Faster 0.5ms response with excellent color accuracy across wide IPS viewing angles.
- Rich color: 99% sRGB color coverage delivers vivid, detailed imagery with strong accuracy.
- Eye comfort: TÜV Rheinland 3‑star certified display lowers blue light while preserving color quality.
NVIDIA’s developer integration guidance states: “Incorrect or missing jitter can lead to poor anti-aliasing and increased flickering.” Jitter is part of the data a game renderer supplies to reconstruction features. If a flicker remains isolated to one title after the player-facing settings checks, fixing an incorrect or missing engine input may require a game update rather than a setting change.
Reduce ghost trails and moving-object artifacts
Compare Frame Generation on and off, and test motion blur separately. NVIDIA’s Streamline Frame Generation checklist connects incorrect scene inputs with increased ghosting; it also notes that missing or incorrect inputs can cause blurry objects, increased flickering, and unstable HUD or UI. Excessive motion blur can add image-quality artifacts when generated frames are enabled, so reducing motion blur is a useful check.

These are possible causes, not a diagnosis of every ghost trail. If the artifact persists with Frame Generation off, investigate the other active DLSS components and game settings rather than assuming Frame Generation is responsible.

Recognize when the game may need a fix
Some DLSS problems depend on renderer data players cannot directly edit. NVIDIA’s developer guidance identifies issues involving jitter, motion vectors, exposure, mip-map bias, and other inputs or buffers. For Ray Reconstruction, missing mip-map bias can make textures appear blurry, smudgy, or low-resolution. A player can test available game and app settings, but generally cannot supply or correct these engine-level inputs.

If an artifact survives a controlled comparison and appears confined to one game, capture a short clip and report the game version, GPU, driver and app versions, resolution, active DLSS components, modes or presets, and the steps that reproduce it to the game developer. This gives the developer actionable details without treating a general integration checklist as proof of your particular cause.
What DLSS 4.5 changes—and what it does not establish
In its 2026 announcement, NVIDIA said its DLSS 4.5 Ray Reconstruction model has 35% more compute capability than the prior model and processes 20% more parameters while maintaining similar performance. Those figures describe NVIDIA’s model comparison; they are not claims of 35% better image quality, 20% sharper images, or 20% faster performance. See NVIDIA’s DLSS 4.5 Ray Reconstruction announcement for its description of the update.
A newer model or compatible GPU is not, on its own, an established fix for artifacts in a compatible game. Start with the feature-by-feature comparison and title-specific troubleshooting instead.
