DLSS adds a small amount of latency in most cases, but the trade-off is usually worth it

DLSS (Deep Learning Super Sampling) is Nvidia's upscaling technology that renders games at a lower resolution and uses AI to enlarge the image to your monitor's native resolution. This process does introduce latency — the delay between your input and what appears on screen — but the amount varies depending on which DLSS mode you use and how your GPU handles the workload. In most games, the latency increase is small enough that you won't notice it, and the performance gain from running at lower resolution often outweighs the slight delay.

The latency added by DLSS is typically measured in single-digit milliseconds. Nvidia's own testing shows DLSS Quality mode adds around 1 to 2 milliseconds on RTX 40-series cards, while Performance mode may add slightly more. For context, a 60 Hz monitor displays a new frame every 16.7 milliseconds, so 1 to 2 milliseconds is a small fraction of that time.

Key Takeaways

  • DLSS Quality mode adds roughly 1 to 2 milliseconds of latency, which is imperceptible to most players.
  • DLSS Performance mode may add slightly more latency than Quality mode, but the frame rate boost often makes input feel more responsive overall.
  • The latency impact depends on your GPU model, driver version, and the specific game engine being used.
  • For competitive games where latency matters most, test DLSS in your specific title before deciding whether to enable it.

How DLSS creates latency

DLSS adds latency because the upscaling process itself takes time. Your GPU must render the frame at the lower resolution, run the AI upscaling algorithm, and then output the result — all of this happens between the moment you press a button and the moment the final image reaches your monitor. This is separate from the latency your GPU already introduces by processing frames.

The upscaling step is where the delay comes from. Instead of simply displaying what your GPU rendered, the system must process that lower-resolution image through Nvidia's neural network before sending it to your monitor. Even though this happens very quickly, it still adds a measurable delay that sits on top of your existing GPU and monitor latency.

Why the latency often goes unnoticed

Even though DLSS adds latency, you may not feel it because the frame rate improvement usually compensates. If DLSS lets you jump from 60 frames per second to 100 frames per second, each frame arrives more frequently, which makes the overall experience feel more responsive despite the slight delay in each individual frame.

Your brain perceives responsiveness as a combination of latency and frame rate. A game running at 100 fps with 2 extra milliseconds of latency often feels snappier than a game running at 60 fps with zero DLSS latency, because frames are arriving more often. This is why many competitive players enable DLSS even in latency-sensitive games — the frame rate gain outweighs the small latency cost.

DLSS modes and their latency differences

Nvidia offers several DLSS modes, and they have different latency profiles. DLSS Quality uses a higher internal resolution (usually around 67 percent of your monitor's resolution), which means less upscaling work and lower latency. DLSS Balanced sits in the middle. DLSS Performance uses the lowest internal resolution and does the most upscaling, which theoretically adds more latency, though the difference is usually under 1 millisecond.

DLSS Frame Generation, available on RTX 40-series cards, is different — it creates entirely new frames using AI rather than upscaling. This technology can add more noticeable latency because it introduces an extra frame of delay, though Nvidia has worked to minimize this in recent driver updates. If latency is your primary concern, stick with DLSS Quality or Balanced rather than Frame Generation.

Games where DLSS latency matters most

In single-player games like Cyberpunk 2077 or Starfield, the small latency increase from DLSS is irrelevant — you won't notice it, and the visual quality improvement is obvious. In competitive multiplayer games like Counter-Strike 2, Valorant, or Apex Legends, latency is more noticeable because your reaction time directly affects your performance.

Even in competitive games, however, DLSS Quality mode is usually safe. Professional esports players have used DLSS in tournaments, which suggests the latency is low enough not to matter at the highest skill levels. If you play competitively, test DLSS in your specific game before a ranked session — some games handle DLSS better than others, and your own sensitivity to latency varies.

How to measure DLSS latency yourself

If you want to know the exact latency impact in your setup, you can use tools like FrameView (from Nvidia) or FCAT to measure frame times with and without DLSS enabled. Most gaming monitors also have built-in latency testing features. The difference you measure will depend on your specific GPU, driver version, and game.

A simpler approach is to enable DLSS Quality mode in a game you play regularly and pay attention to how the game feels for a few hours. If you notice no difference in responsiveness, the latency is below your perception threshold, and you can safely use DLSS to boost your frame rate. If you feel a difference, try DLSS Balanced or disable it entirely.

DLSS versus other upscaling technologies

AMD's FSR (FidelityFX Super Resolution) and Intel's XeSS are competing upscaling technologies that also add small amounts of latency. FSR tends to add slightly less latency than DLSS because it uses traditional upscaling rather than AI, but the difference is minimal — usually under 1 millisecond. XeSS sits somewhere in between.

For most players, the choice between these technologies should be based on image quality and compatibility, not latency. All three add negligible latency compared to the frame rate gains they provide, so pick whichever one your GPU supports and produces the image quality you prefer.

Frequently Asked Questions

Does DLSS add more latency than native resolution?

Yes, DLSS adds latency compared to rendering at native resolution with no upscaling. However, the latency is small (1 to 2 milliseconds), and the frame rate gain usually makes the overall experience feel more responsive. If you're comparing DLSS at 100 fps to native resolution at 60 fps, DLSS will feel faster despite the added latency.

Is DLSS latency noticeable in fast-paced games?

For most players, no. The latency from DLSS Quality mode is below the threshold most people can perceive. In competitive games, the frame rate improvement often outweighs the latency cost. If you're extremely sensitive to latency, test it yourself in your game before committing.

Does DLSS Frame Generation add more latency than regular DLSS?

Yes, Frame Generation introduces an extra frame of delay because it creates synthetic frames. This can add 1 to 2 additional milliseconds compared to DLSS upscaling alone. If latency is critical, use DLSS Quality or Balanced upscaling without Frame Generation enabled.

Can I reduce DLSS latency by changing settings?

Use DLSS Quality mode instead of Performance mode for slightly lower latency. Disable Frame Generation if you have it enabled. Beyond that, latency is determined by your GPU and the game engine — you can't adjust it further through settings.

Do newer graphics cards have lower DLSS latency?

Generally yes. RTX 40-series cards handle DLSS with lower latency than RTX 30-series cards, and RTX 30-series is lower than RTX 20-series. However, the differences are small — usually under 1 millisecond — so an older card's DLSS latency is still unlikely to be noticeable.
