Use DLSS Super Resolution first when your game offers it and your GeForce RTX GPU supports it. DLSS uses AI, motion vectors, and data from previous frames to reconstruct a higher-resolution image. Choose NVIDIA Image Scaling (NIS) when DLSS is unavailable, your hardware is outside the RTX ecosystem, or you need a spatial upscaler with broader stated platform support.
That is a starting point, not a universal benchmark result. The better setting depends on the game’s implementation, output resolution, performance target, and the artifacts you can tolerate. Test both options in the same scene and compare them at similar visual quality rather than relying on identical labels such as Quality or Performance.
DLSS and NIS at a glance
| Question | DLSS Super Resolution | NVIDIA Image Scaling |
|---|---|---|
| Reconstruction method | AI-assisted temporal reconstruction using motion data and prior frames | Spatial upscaling and sharpening from the current frame |
| Processing hardware | GeForce RTX Tensor Cores for DLSS features | Documented for NVIDIA GTX or newer, AMD, Intel, and consoles, depending on integration |
| Temporal information | Yes; uses motion vectors and history from earlier frames | No; works from the current frame |
| Typical reason to select it | Your RTX game supports DLSS and you want temporal reconstruction | DLSS is unavailable or broader hardware reach is more important |
| Where it appears | Usually an in-game option; some controls can also be exposed through NVIDIA App overrides | In-game or driver/developer integration, depending on the title |
| Universal quality winner? | Not established; results vary by game, mode, resolution, and implementation | Not established; results vary by game, mode, resolution, and implementation |
NVIDIA’s own documentation describes DLSS as using AI, motion vectors, and prior frames, while spatial upscalers use only the current frame and a non-AI algorithm. That technical distinction explains why the two options can look different even when they render at a similar internal resolution.

DLSS is a collection of neural-rendering features for GeForce RTX hardware. DLSS Super Resolution is the upscaling component: the game renders at a lower internal resolution, then a neural model reconstructs an image at the display’s output resolution. NVIDIA describes the goal as boosting performance by using AI to produce higher-resolution frames from lower-resolution input.

Temporal reconstruction, not just a sharper resize
Super Resolution can combine the current frame with motion vectors and information accumulated from previous frames. In principle, that gives the reconstruction process more evidence for fine geometry, edges, and moving detail than a filter that sees one frame at a time. It also means the result depends heavily on the quality of the game’s motion vectors, exposure data, anti-aliasing setup, and integration.
Temporal methods can show benefits in motion, but they can also produce failure cases. Poor vectors or rapidly changing effects may lead to ghosting, trailing, shimmering, unstable foliage, or reconstruction errors around particles. These are implementation and scene issues, not proof that every DLSS mode behaves the same way.
DLSS features are separate
Do not treat every DLSS label as one capability. NVIDIA lists Super Resolution alongside features such as Ray Reconstruction, DLAA, and frame generation. A game may support one, several, or none of these features, and GPU requirements differ. Selecting DLSS Super Resolution does not automatically mean that frame generation or Ray Reconstruction is available.

Current version context
NVIDIA’s developer page, updated in September 2026, describes DLSS 4.5 and a second-generation transformer model for Super Resolution. In a January 2026 announcement, NVIDIA stated that DLSS 4.5 Super Resolution is for GeForce RTX GPUs, while Dynamic Multi Frame Generation and 6X Multi Frame Generation are for GeForce RTX 50 Series. The RTX 50 Series requirement applies to those frame-generation features, not to every DLSS feature.
The same January announcement reported more than 400 games and applications with DLSS 4.5 Super Resolution availability at that time. That was a vendor-published, time-bound count; consult NVIDIA’s current game list before treating it as a present-day total.
What NVIDIA Image Scaling does
NVIDIA Image Scaling (NIS) is a spatial upscaler with a sharpening algorithm. It analyzes the current frame, enlarges it to the target output resolution, and applies sharpening intended to restore perceived detail. It does not use a neural model, motion vectors, or a history of earlier frames.
Broader stated platform reach
NVIDIA describes the NIS SDK as open source and cross-platform. Its listed hardware includes NVIDIA GTX or newer, AMD, Intel, and consoles; its listed operating systems include Windows and Linux, with DirectX 11, DirectX 12, and Vulkan support. Those are SDK capabilities, not a guarantee that a particular game exposes NIS. A developer still has to integrate it, or a driver and game combination must provide a usable path.
What a spatial method means in practice
Because NIS works from one frame, it avoids some temporal-history problems but has less information with which to reconstruct detail. At aggressive scaling ratios, thin geometry, text, foliage, and diagonal edges may look softer or show aliasing. Sharpening can make an image appear clearer, yet excessive sharpening can create halos, ringing, or a noisy appearance. The useful setting is the one that meets your frame-rate target without distracting artifacts on your display.
The differences that matter when choosing
1. Game and hardware support
Support comes first. A compatible GPU alone does not add a menu option to a game. Check the game’s graphics settings, its current patch notes, and the developer’s feature list. DLSS requires a compatible GeForce RTX path. NIS can reach more vendor families in the SDK documentation, but the title must still include or expose the feature.

2. Detail stability during motion
DLSS has access to temporal information and motion vectors; NIS does not. NVIDIA characterizes that extra information as a way to improve image stability in motion. Treat this as NVIDIA’s technical description rather than an across-the-board independent result. In some games, a well-integrated NIS implementation may look preferable to a poorly integrated temporal implementation.
3. Performance at comparable quality
Both methods can increase frame rate by rendering fewer pixels internally. The gain depends on the internal scale, output resolution, GPU workload, CPU limits, ray-tracing settings, and the game engine. Mode names are not standardized: one game’s Quality setting may use a different scale or reconstruction path from another game’s Quality setting.

4. Access and controls
DLSS and NIS may appear as in-game options, driver options, or both. An in-game implementation usually exposes the game’s intended presets and sharpening controls. Driver-level controls can be useful when a title lacks a native option, but they may not have the same motion data or integration quality as a native implementation.
How to decide in a real game
- Confirm the output target. Note whether you are playing at 1920×1080, 2560×1440, 3840×2160, or another resolution. Upscaling artifacts are more visible at some combinations of internal and output resolution than others.
- Check the game’s feature list. Look for DLSS Super Resolution and NIS separately. Do not assume that a title offering one automatically offers the other.
- Verify your GPU path. DLSS Super Resolution requires GeForce RTX support. NIS is documented across a broader set of hardware, but the game or driver must expose it.
- Set a repeatable baseline. Keep texture quality, anti-aliasing, shadows, ray tracing, field of view, and display mode unchanged while testing. Record the output resolution and refresh rate.
- Start with DLSS on RTX hardware. Select a mode that gives your desired performance without obvious reconstruction errors. This is NVIDIA’s technology-based starting recommendation, not a universal benchmark conclusion.
- Try NIS when DLSS is missing or unsuitable. Choose an internal scale that provides enough performance, then adjust sharpening conservatively. If NIS is available only through a driver, restart the game after changing the setting if the title does not detect the change immediately.
- Use the same scene for comparison. Stand in one location, move the camera through foliage and geometry, and repeat the same traversal. Compare still detail and motion rather than a single screenshot.
- Match visual quality before comparing frame rates. NVIDIA cautions that similarly named modes are not necessarily equivalent. If one option looks substantially softer or shimmers more, change its scale or sharpening before judging performance.
- Check frametime, not only the average FPS counter. Look for consistent delivery during traversal, combat, particle effects, and camera pans. A higher average can still feel worse if frametime spikes are more frequent.
- Keep the setting that meets your priorities. If both look similar, use the one with the steadier frame time or simpler access. If neither is acceptable, reduce a different GPU-heavy setting or use native resolution at a lower quality preset.
How to compare image quality fairly
A fair comparison changes one reconstruction method at a time. Use the same game build, save point, display calibration, sharpening settings, and camera path. Capture or observe at native output resolution; judging a 4K output from a scaled-down web image can hide the differences you are trying to measure.
Inspect these areas
- Fine geometry: wires, railings, fence patterns, hair, and thin branches reveal edge stability.
- Text and HUD elements: look for softness, halos, or crawling edges around small lettering.
- Motion: pan across foliage, fences, and high-contrast objects to check for trails, shimmer, or breakup.
- Particles and transparency: smoke, sparks, glass, and water can expose missing or inaccurate motion data.
- Specular highlights: bright reflections and wet surfaces may flicker when reconstruction has difficulty tracking changes.
- Dark scenes: shadow detail and temporal stability can look different from bright daylight scenes.
Repeat the check at the refresh rate you actually use. A mode that looks acceptable in a paused image may reveal artifacts once the camera moves at 120 Hz or higher.
Performance: what you can and cannot infer
Rendering below the output resolution reduces pixel work, so either method can raise frame rates in a GPU-limited game. The scale factor is decisive: a lower internal resolution generally offers more performance but less source detail. At 4K output, a given percentage represents many more pixels than it does at 1080p, so the visual and performance trade-off will not transfer directly between displays.
Upscaling cannot remove a CPU bottleneck. If the processor limits the game, lowering the internal render resolution may change the image while leaving frame rate nearly unchanged. Likewise, effects such as ray tracing, simulation, shader compilation, and streaming can dominate frame time even after the upscaler reduces rasterized pixel cost.
No current independent, cross-game benchmark establishes a universal FPS winner between DLSS and NIS. NVIDIA’s older comparison material contains title-specific resolution, pixel-count, and performance examples from 2021; those examples explain the method but should not be treated as current results for every game or GPU.
Using NVIDIA App controls
NVIDIA’s March 2025 NVIDIA App article described DLSS overrides, presets, and custom scaling from 33% to 100%. In that release context, the article listed Game Ready or Studio Driver 572.83 WHQL or newer as a requirement. Driver and app behavior can change, so verify the current NVIDIA App documentation before following those exact labels or driver numbers.

When an override can help
- The game supports DLSS internally but offers limited presets.
- You want to test a custom scale between the available in-game modes.
- You are troubleshooting a title whose native preset appears inconsistent after an update.
Why native integration may still be preferable
A driver override cannot add game-specific motion vectors, exposure data, or UI handling that the developer did not provide. If the native option is well integrated, it may produce more reliable reconstruction than a generic external setting. Change one control at a time and return to the game’s default if the override causes ghosting, crashes, or unexpected sharpening.

DLSS names can refer to a family of technologies rather than one fixed requirement. For example, NVIDIA’s January 2026 announcement separates RTX-wide DLSS 4.5 Super Resolution from RTX 50 Series Dynamic Multi Frame Generation and 6X Multi Frame Generation. Check the requirement for the specific feature you want:
| Feature or label | What to verify |
|---|---|
| DLSS Super Resolution | GeForce RTX compatibility, game support, and the title’s implementation |
| Ray Reconstruction | Whether the game supports it and whether your selected rendering path uses ray-traced effects |
| DLAA | Whether the title offers native-resolution AI anti-aliasing; it is not an upscaling mode |
| Frame generation | The exact DLSS generation feature and GPU-series requirement; do not assume RTX-wide support |
Read the game’s own menu and current NVIDIA documentation together. A game may update its DLSS model, presets, or supported GPU list independently of the marketing name shown in the menu.
Common problems and fixes
DLSS is missing from the menu
- Confirm that the GPU is a GeForce RTX model and that the game build supports DLSS.
- Update the game and install a current graphics driver appropriate for your operating system.
- Check whether another renderer, such as a legacy API or compatibility mode, hides the option.
- Verify that the feature is not disabled by a configuration file or a competitive preset.
NIS is missing
- Check whether the game integrated NIS or whether your current driver exposes a usable image-scaling control.
- Confirm the renderer and operating system are supported by the specific integration.
- Restart the game after enabling a driver-level option.
The image is too soft
- Use a less aggressive scale so the internal image contains more source detail.
- Reduce sharpening if halos or ringing are mistaken for clarity, then reassess at native output resolution.
- Check that the display is not applying a second scaling or sharpening pass.
Ghosting or shimmering appears
- Compare a different DLSS mode and inspect the same object while moving the camera.
- Test NIS in the identical scene to determine whether the artifact is tied to temporal reconstruction.
- Update the game if the developer has published a rendering fix; otherwise choose the mode with the least distracting artifact for your play style.
Which option fits common situations?
You have an RTX GPU and the game supports DLSS
Start with DLSS Super Resolution. Choose the least aggressive mode that reaches your performance target, then inspect motion and fine detail. Keep NIS as a fallback if the game’s DLSS implementation produces artifacts you find more distracting.
You have a non-RTX GPU
DLSS Super Resolution is not the relevant path. Use NIS if the game or driver provides it, or use another upscaler supplied by the title. NIS’s documented hardware reach includes NVIDIA GTX or newer, AMD, Intel, and consoles, subject to integration.
The game has NIS but no DLSS
Use NIS and tune its scale and sharpening against the display resolution. The absence of DLSS is a game-support limitation, not evidence that NIS will perform identically across other titles.
You care most about competitive latency
Test both at the same frame-rate target and measure how the game feels with your display and input settings. Upscaling can increase GPU headroom, but frame-generation features are separate from Super Resolution and can have different latency behavior. Do not select a frame-generation option merely because the menu also says DLSS.
You are considering a GPU purchase solely for this choice
An RTX card is relevant if access to DLSS is a specific goal. It is not required to use NIS, whose SDK documentation covers a broader hardware range. Verify the exact model’s supported DLSS features, current driver support, and availability before buying; a generic RTX label does not guarantee every newer feature.
Bottom line
For an RTX-equipped system in a DLSS-enabled game, try DLSS Super Resolution first because its temporal, AI-assisted approach is designed to reconstruct detail from motion data and previous frames. Use NIS when DLSS is unavailable, when you need broader hardware coverage, or when its spatial result looks better in that particular title. Make the final choice by testing the same scene at matched visual quality, watching motion artifacts and frametime as well as the FPS counter.
