Lossless scaling lets your graphics card upscale lower resolutions without the blurriness you'd normally see, but it only works if your game is actually running at that lower resolution

Lossless scaling is a feature built into some graphics cards — primarily newer Nvidia and AMD models — that enlarges a lower-resolution image to fit your monitor's native resolution without the soft, blurry look of traditional upscaling. The catch: your game has to be running at a resolution lower than your monitor's native size for lossless scaling to do anything at all. If your game is already running at your monitor's full resolution, lossless scaling is not active, and there is nothing to scale.

The reason this matters is that many people turn on lossless scaling expecting a performance boost or image quality improvement, then wonder why they do not see a difference. Usually it is because their game is already at native resolution. Lossless scaling only engages when there is a mismatch between what the game is rendering and what the monitor displays.

Key Takeaways

  • Lossless scaling only activates when your game runs at a resolution lower than your monitor's native resolution — if your game is already at native resolution, lossless scaling does nothing.
  • You can check your game's actual rendering resolution in the in-game graphics settings or by using monitoring software like MSI Afterburner or GPU-Z.
  • Turning on lossless scaling when your game is already at native resolution will not improve performance or image quality.
  • Lossless scaling works best when you intentionally run a game at a lower resolution to gain frame rate, then let the graphics card enlarge it to fill your screen.

How to tell if lossless scaling is actually working

The simplest way to know whether lossless scaling is engaged is to check whether your game's rendering resolution is lower than your monitor's native resolution. Your monitor's native resolution is the size it was designed to display — typically 1920×1080, 2560×1440, or 3840×2160 for modern displays.

Open your game's graphics settings and look for the resolution option. If the number you see there matches your monitor's native resolution, lossless scaling is not active. If it is lower — say, 1440×810 on a 1920×1080 monitor — then lossless scaling can work. You can also use free monitoring tools like MSI Afterburner or GPU-Z to watch your game's rendering resolution in real time while you play.

When lossless scaling actually helps your frame rate

Lossless scaling is useful when you want more frames per second but do not want the blurry appearance of traditional upscaling. The workflow is: set your game to a lower resolution in its graphics menu, enable lossless scaling in your graphics driver settings, and the card will enlarge the lower-resolution image to fit your monitor. You get the performance gain from rendering at a smaller size, plus the sharper image that lossless scaling provides compared to older upscaling methods.

This is different from running your game at native resolution with lossless scaling on. That combination does nothing — your game is already at full size, so there is nothing for lossless scaling to enlarge. The feature only works when there is a gap between what the game renders and what the monitor displays.

Nvidia DLSS and AMD FSR are different from lossless scaling

Do not confuse lossless scaling with Nvidia DLSS (Deep Learning Super Sampling) or AMD FSR (FidelityFX Super Resolution). Those are built into individual games and use artificial intelligence or advanced algorithms to upscale lower resolutions while preserving detail. They are more sophisticated than lossless scaling and often produce better image quality, but they only work in games that have them built in.

Lossless scaling, by contrast, works on any game, any resolution, any time — it is a blanket feature in your graphics driver. The trade-off is that it is simpler and less intelligent than DLSS or FSR. If your game supports DLSS or FSR, using those is usually the better choice. Lossless scaling is the fallback for games that do not have those features.

Why enabling lossless scaling at native resolution does not help

Some people enable lossless scaling hoping it will improve their frame rate or image quality without changing their game's resolution. It will not. Lossless scaling only enlarges an image; it cannot create performance gains or sharpen an image that is already at full size. If your game is rendering at 1920×1080 on a 1920×1080 monitor, the graphics card has nothing to scale, and lossless scaling remains inactive.

The confusion often comes from marketing or forum posts that make lossless scaling sound like a universal performance tool. It is not. It is a specific solution for a specific situation: when you have deliberately lowered your game's resolution to gain frame rate, and you want the upscaled image to look as sharp as possible.

How to set up lossless scaling if you want to use it

For Nvidia cards, lossless scaling is called Integer Scaling and lives in the Nvidia Control Panel. Open the Control Panel, go to Display, and look for "Scaling" or "Integer Scaling". Turn it on. Then in your game, set the resolution to something lower than your monitor's native size — for example, 1440×810 on a 1920×1080 monitor — and the card will enlarge it using integer scaling.

For AMD cards, the feature is in Radeon Settings under Display. Look for "GPU Scaling" and turn it on, then set your game to a lower resolution. AMD's version works similarly: the card enlarges the lower-resolution image to fill your monitor.

After you enable it, the key step is actually changing your game's resolution downward. Without that step, lossless scaling will not set up, and you will see no change in performance or image quality.

When lossless scaling is worth using

Lossless scaling makes sense if you are playing a game that does not support DLSS or FSR, you want more frame rate than native resolution gives you, and you prefer the look of lossless scaling to traditional blurry upscaling. It is most useful on high-refresh-rate monitors where the difference between 60 and 100 frames per second is noticeable, or on older games that do not have modern upscaling built in.

It is not worth using if your game already runs at native resolution with the frame rate you want, or if your game has DLSS or FSR available. In those cases, lossless scaling will either do nothing or be inferior to the game's native upscaling method.

Frequently Asked Questions

Does lossless scaling work if my game is already at native resolution?

No. Lossless scaling only works when your game is rendering at a lower resolution than your monitor's native size. If your game is already at native resolution, lossless scaling is inactive and will not change your performance or image quality.

Will turning on lossless scaling improve my frame rate?

Only if you also lower your game's resolution. Lossless scaling itself does not improve frame rate — it just enlarges a lower-resolution image. The frame rate gain comes from rendering at a smaller resolution. Lossless scaling only makes that smaller image look sharper.

Is lossless scaling better than DLSS or FSR?

No. DLSS and FSR are more advanced and usually produce better image quality. Use them if your game supports them. Lossless scaling is a simpler fallback for games that do not have those features built in.

How do I know if lossless scaling is actually on?

Check your game's rendering resolution in its graphics settings. If it is lower than your monitor's native resolution, lossless scaling is active. If it matches your monitor's native resolution, lossless scaling is not doing anything.
