Use NVIDIA Image Scaling (NIS) when DLSS is not available, your hardware is outside the RTX range, or the game exposes NIS as the practical option. The right choice still depends on the game, output resolution, upscaling mode, and the artifacts you can tolerate.
DLSS and NIS are not two names for the same scaler. DLSS uses AI, motion data, and information from previous frames; NIS is a spatial algorithm that works from the current frame. That difference affects moving detail, edge stability, hardware compatibility, and how each setting should be tested.

DLSS and NIS at a glance
| Characteristic | NVIDIA DLSS Super Resolution | NVIDIA Image Scaling (NIS) |
|---|---|---|
| Reconstruction method | AI-assisted temporal reconstruction using motion information and prior frames | Spatial upscaling and sharpening from the current frame |
| Specialized hardware | GeForce RTX Tensor Cores | No RTX Tensor Core requirement stated by NVIDIA |
| Stated platform reach | GeForce RTX hardware, with individual DLSS features varying by GPU and game | NVIDIA GTX or newer, AMD, Intel and consoles are listed in NVIDIA’s SDK documentation; actual game support depends on integration |
| Temporal information | Uses motion vectors and previous frames | Does not use previous frames; it processes the current frame |
| Game availability | Requires DLSS integration or a supported driver/game path | Requires NIS integration, a supported driver path, or a game option exposing it |
| Best starting use | An RTX system in a game with DLSS Super Resolution when image stability matters | A game without DLSS, or a system where broader vendor support matters |
These are architectural and support distinctions, not a promise that one setting wins every visual comparison. NVIDIA’s own documentation describes the temporal information in DLSS as an advantage for stable detail in motion, while describing spatial upscaling as a performance-oriented trade-off. Those are vendor characterizations; no current independent cross-game benchmark establishes a universal winner.

What DLSS actually does
DLSS is a group of neural-rendering features built for GeForce RTX GPUs. The part relevant to this comparison is DLSS Super Resolution. A game renders an internal image below the display’s output resolution, then DLSS uses AI running on RTX Tensor Cores to reconstruct a higher-resolution frame. Motion vectors, depth or other engine data, and earlier frames provide context that is unavailable to a scaler looking at one image in isolation.

NVIDIA describes DLSS Super Resolution as boosting performance by using AI to output higher-resolution frames from a lower-resolution input. Rendering fewer pixels is the main source of the speed gain; reconstruction attempts to preserve more of the detail that would otherwise be lost when simply enlarging a low-resolution image.
DLSS features are separate
“DLSS” on a game’s settings menu may refer to several capabilities. Super Resolution is the upscaler. Ray Reconstruction is designed to improve ray-traced lighting reconstruction. DLAA uses the DLSS technology for anti-aliasing at native resolution rather than lowering the internal render resolution. Frame Generation creates additional frames between rendered frames. These features have different hardware and game requirements, so support for one does not imply support for all of them.
NVIDIA’s current developer material, checked in October 2026 and marked updated in September 2026, describes DLSS 4.5, including a second-generation transformer model for Super Resolution. NVIDIA’s January 2026 announcement distinguishes RTX-wide DLSS 4.5 Super Resolution from Dynamic Multi Frame Generation and 6X Multi Frame Generation, which it identifies as GeForce RTX 50 Series features. Do not interpret the 50 Series requirement for those frame-generation modes as a requirement for every DLSS feature.

Check NVIDIA’s current game list and the individual game’s patch notes before treating availability as current.
What NVIDIA Image Scaling does
NVIDIA Image Scaling, usually abbreviated NIS, is a spatial upscaler combined with sharpening. It takes the rendered image from the current frame, enlarges it toward the selected output resolution, and applies sharpening to recover perceived edge contrast. It does not use motion vectors or a history of previous frames.
NVIDIA describes the NIS SDK as open source and cross-platform. Its listed hardware includes NVIDIA GTX or newer GPUs, AMD and Intel GPUs, and consoles; its listed operating systems include Windows and Linux, with DirectX 11, DirectX 12 and Vulkan APIs. Those are SDK capabilities, not a guarantee that every game exposes NIS on every listed platform. A developer must integrate it, or a supported driver or application path must make it available.
The broader hardware list is NIS’s defining practical advantage. You can consider it on a non-RTX NVIDIA card or on AMD or Intel graphics when the game or platform offers the option. It does not, however, make NIS automatically available in a title that has no integration.
Which one should you choose?
Choose DLSS Super Resolution first when all of these are true
- Your graphics card is a GeForce RTX model supported by the game’s DLSS implementation.
- The game actually offers DLSS Super Resolution at your chosen API and display mode.
- You prefer temporal reconstruction and are willing to inspect motion, foliage, fine geometry and transparencies for artifacts.
- You want to use the game’s supported quality modes rather than depend on a generic spatial scaler.
This is a starting recommendation, not a benchmark result. DLSS’s use of temporal data can help preserve moving detail and reduce instability, but implementation quality differs between games. A poorly integrated or aggressively tuned implementation can still show ghosting, shimmer, softness or reconstruction errors.
Choose NIS when DLSS is unavailable or hardware reach matters
- The game has an NIS option but no DLSS Super Resolution option.
- Your GPU is a GTX, AMD or Intel model, or you are playing on a supported console platform.
- You need a simple spatial upscaler and accept that current-frame processing cannot recover information from prior frames.
- You are comparing several systems and want a technique documented across more GPU vendors.
NIS can improve frame rate by allowing the game to render below the display resolution. The cost is a spatial image-quality trade-off: fine detail, diagonals and moving elements may look less stable than with a well-implemented temporal reconstruction.
Do not choose by the mode name alone
“Quality,” “Balanced” and “Performance” are labels, not a common standard. NVIDIA explicitly cautions that similarly named modes are not necessarily equivalent. One game may render its Quality mode at a different internal resolution from another, and the sharpening or reconstruction settings can differ as well. Compare the final image at a matched quality level instead of assuming that two modes with the same name render the same number of pixels.

Hardware and feature requirements
RTX requirements for DLSS
DLSS Super Resolution is designed for GeForce RTX hardware because it relies on RTX Tensor Cores. Having an RTX card still does not guarantee a DLSS menu entry: the game must support DLSS, and the relevant feature may depend on the game’s version, rendering API, operating mode or driver.
DLSS features should be checked individually. Super Resolution may be available across RTX generations, while a newer frame-generation mode can be restricted to a particular generation. Ray Reconstruction, DLAA and frame generation also require separate game integration. Confirm the exact feature and GPU requirement rather than treating “DLSS supported” as a blanket statement.
NIS platform requirements
NVIDIA’s SDK documentation lists GTX or newer NVIDIA graphics, AMD and Intel graphics, and consoles, with Windows and Linux support and DirectX 11, DirectX 12 and Vulkan APIs. The list describes what the SDK supports; a game’s implementation can be narrower. A title may expose NIS only on one API, only through a particular driver path, or not at all.
Display and resolution considerations
Both techniques are most useful when the GPU is the performance limit and the game can render internally below the display’s output resolution. At a low output resolution, aggressive scaling can make text, thin geometry and distant objects difficult to read regardless of the algorithm. At very high output resolutions, the same internal percentage may require substantially more pixels and may deliver a different performance result. Evaluate the exact resolution and refresh rate you use rather than transferring a setting from another monitor.
How to test DLSS and NIS fairly
A reliable comparison is a controlled in-game check, not a side-by-side based only on the FPS counter. Follow the same procedure for each option.
- Confirm availability. Open the game’s graphics or display settings and record which of DLSS Super Resolution, NIS, another upscaler and native resolution are actually offered. Note the rendering API and whether a restart is required.
- Lock the test scene. Use the same save point, benchmark run or repeatable camera path. Keep output resolution, field of view, texture quality, lighting, ray-tracing options, shadows, anti-aliasing and frame caps unchanged.
- Record the internal mode and sharpening. Write down the exact label, percentage or resolution for each option. If the game exposes a sharpening slider, keep it equal where possible or record the value separately; sharpening can make a softer image appear more detailed while increasing halos.
- Warm up each setting. Let shader compilation and asset streaming settle before recording performance. A first run can include work unrelated to the upscaler.
- Inspect still detail. Look at foliage, wires, fences, hair, text, distant geometry and specular highlights. Check whether edges are crisp, overly soft or surrounded by halos.
- Inspect motion. Pan the camera, follow a moving character and watch particles, reflections and transparencies. Temporal reconstruction can show ghost trails or history errors; spatial scaling can show crawling edges or loss of detail as objects move.
- Measure frame-time behavior. Use the same overlay or benchmark tool for average frame rate, frame-time consistency and, if available, low-percentile frame rates. Do not compare a higher frame rate if the image is visibly worse than the other setting.
- Match image quality before judging speed. NVIDIA recommends comparing modes at similar visual quality because equal labels do not imply equal internal resolutions. If one option is visibly softer, lower its scaling aggressiveness or choose a different mode before drawing a performance conclusion.
- Repeat after changing resolution or ray tracing. A setting that works at 1080p can behave differently at 1440p or 4K, and ray-traced effects can change which details are most difficult to reconstruct.
The result you want is the setting that delivers acceptable motion stability and detail at the frame rate your display and game require. There is no reason to keep a nominally faster option if its artifacts are distracting.
Using the settings in a game
When the game has both options
- Start at the game’s native output resolution and open its upscaling or anti-aliasing section.
- Select DLSS Super Resolution and choose a conservative quality mode first. Apply the setting and check whether the game requires a restart.
- Inspect the same scene while stationary and moving. Adjust the mode only after identifying whether the limitation is performance, softness, shimmer or ghosting.
- Switch to NIS using the closest documented internal resolution or percentage, then repeat the same inspection. Keep unrelated graphics settings unchanged.
- Retain the option that meets your visual and frame-time requirements, not automatically the one with the larger FPS number.
When the game has only NIS
Enable NIS in the game’s upscaling or resolution-scaling controls if it is exposed. If the game offers a render-resolution percentage and a separate sharpening control, change one at a time. Excessive sharpening can create bright outlines and emphasize noise; reducing the sharpening value can improve readability even when the internal resolution is unchanged.
When the game has only DLSS
Use the available DLSS Super Resolution modes and test them in motion. If the menu offers additional DLSS features, treat them separately: enabling frame generation changes latency and frame-pacing behavior, while DLAA changes anti-aliasing at native resolution. Those choices are not substitutes for deciding between DLSS Super Resolution and NIS.
NVIDIA App overrides and changing driver details
NVIDIA’s March 2025 NVIDIA App article described DLSS overrides, presets and custom scaling from 33% to 100%, with Game Ready or Studio Driver 572.83 WHQL or newer required in that release context. These labels, controls and driver requirements are time-sensitive. Before following an App-based procedure, check the current NVIDIA App and driver documentation for your installed version.
An override cannot create full game support where the rendering pipeline lacks the required integration. If an override is offered, apply it only after recording the game’s native settings so you can revert cleanly. Test the resulting image and frame times in the same repeatable scene; a driver-level option can use a different preset or scaling percentage from the game’s own menu.

Common problems and fixes
There is no DLSS or NIS option
First verify the game’s supported features and rendering API. A compatible GPU alone does not add a menu entry. Update the game and graphics driver if the developer or vendor lists support for your version, then check whether a different API, fullscreen mode or restart is required. If the title has no integration or supported driver path, neither setting can be selected legitimately.
The image is soft
Use a less aggressive quality mode or a higher internal resolution. Check for a separate sharpening control, but increase it gradually because sharpening cannot restore detail that was never rendered and can introduce halos. Compare text and fine geometry at the same output resolution before changing other graphics options.
You see ghosting or trails
Ghosting is often associated with temporal reconstruction, but its severity is implementation-specific. Test a higher-quality DLSS mode, disable a problematic post-processing effect if the game allows it, and compare the same moving object with NIS. If NIS removes the trail but produces more edge shimmer or softness, choose according to which artifact is less distracting in your game.

Thin objects shimmer or crawl
Spatial scaling has no previous-frame information to stabilize edges, so fences, wires and foliage may require a higher internal resolution or less sharpening. Check the game’s anti-aliasing interaction and compare a DLSS mode if your RTX hardware and the title support it.
The frame rate rises but the game feels less responsive
Upscaling reduces rendering work, but it does not by itself guarantee lower latency. Check the game’s latency controls, frame cap and synchronization settings separately. If frame generation is enabled, evaluate latency and frame pacing independently from the upscaler decision; frame generation is a distinct DLSS capability.
The NVIDIA App setting does not appear
App features depend on the installed App and driver release, supported game profile and GPU. Verify the current release notes and driver requirement, then return to the in-game option if the profile is unavailable. Do not assume a setting documented in an older App article is still labeled or exposed in the same place.
What the available evidence can and cannot prove
NVIDIA’s technical explanation supports the distinction between temporal DLSS reconstruction and spatial NIS processing. It does not establish one universal frame-rate multiplier or image-quality ranking across every game. NVIDIA’s November 2021 comparison article contains title-specific resolution, pixel-count and performance examples, but those are historical vendor examples rather than current guarantees.

A practical decision checklist
- Game support: Is the option actually present in this title and rendering API?
- GPU: Do you have an RTX card for DLSS, or would NIS’s broader documented platform reach solve the compatibility problem?
- Target output: What resolution and refresh rate are you trying to sustain?
- Visual priority: Are motion stability, fine detail, low latency or maximum frame rate most important?
- Artifact tolerance: Which is less distracting in your game: temporal trails and reconstruction errors, or spatial softness and edge shimmer?
- Comparable test: Have you matched internal image quality rather than comparing mode names?
- Feature separation: Are you evaluating Super Resolution itself, rather than accidentally attributing frame-generation or Ray Reconstruction behavior to the upscaler?
Bottom line for common setups
RTX GPU with DLSS in the game
Start with DLSS Super Resolution, then test its quality modes in a repeatable scene. Keep it if the reconstructed image remains stable in motion and the performance gain meets your target. Switch to another mode or NIS only when the observed artifacts or support limitations make that a better fit.
Non-RTX NVIDIA, AMD or Intel GPU
DLSS Super Resolution is not the general solution because its supported hardware path is GeForce RTX. If the game exposes NIS, it is the documented cross-vendor option to evaluate. If neither scaler is integrated, use the game’s native resolution scaling or another supported upscaler instead.
Game without DLSS
Use NIS when the game supports it and you need additional performance. If NIS is not available, the absence of an option is an integration limitation, not something a compatible GPU alone can fix.
