Enable Nvidia Image Scaling: How to Turn It On

Nvidia Image Scaling (NIS) is a driver-level upscaling feature that renders a game at a lower internal resolution and then upscales it to your monitor’s native resolution, boosting frame rates with a small visual quality trade-off. You can enable it either globally through the Nvidia Control Panel or per-game through the GeForce Experience overlay. This article explains both methods, how NIS differs from DLSS, and how to troubleshoot common issues.

What Is Nvidia Image Scaling?

NIS is a spatial upscaler and sharpener built into Nvidia drivers since version 496.76 (November 2021). Unlike DLSS, which uses dedicated Tensor cores and temporal data (motion vectors) to reconstruct frames, NIS works on a single frame at a time. It applies a directional sharpening filter after upscaling, which helps recover edge detail lost when the image was rendered at a lower resolution.

Because NIS is driver-level, it works with virtually any game, even those without built-in support. It also works on GeForce GTX 10-series and newer GPUs, including cards that do not support DLSS. The feature is especially useful for older or less powerful GPUs that struggle to maintain smooth frame rates at high resolutions.

How to Enable NIS via Nvidia Control Panel

The most reliable method is through the Nvidia Control Panel. Follow these steps:

  1. Right-click on your desktop and select Nvidia Control Panel.
  2. Under 3D Settings, click Manage 3D Settings.
  3. In the Global Settings tab, scroll down to Image Scaling.
  4. Click the toggle to turn it On.
  5. Choose an Off, 25%, 50%, 75%, or 100% sharpening value. A higher percentage means more sharpening, but can introduce halos or ringing artifacts.
  6. Check the Overlay Indicator option if you want a small NIS badge in the corner of your screen while gaming.
  7. Click Apply.

Once enabled, you can adjust the per-game render resolution in the game’s graphics settings. NIS will automatically upscale the image to your monitor’s native resolution.

How to Enable NIS via GeForce Experience

If you have GeForce Experience installed (version 3.26 or later), you can also enable NIS from the in-game overlay:

  1. Launch a game that supports the overlay (most DirectX and Vulkan titles).
  2. Press Alt+Z to open the GeForce Experience overlay.
  3. Click the Game Filter icon (the slider icon).
  4. Click Image Scaling in the left panel.
  5. Toggle it On and adjust the sharpness slider.
  6. Click Done.

Note that this method requires the game to be running and the overlay to be active. Some games may not display the option if they already have their own scaling solution.

NIS vs. DLSS: What’s the Difference?

DLSS (Deep Learning Super Sampling) is Nvidia’s AI-powered upscaling that uses temporal data and Tensor cores. It can often produce better image quality than NIS, especially at lower render resolutions, because it reconstructs frames using motion vectors and previous frames. DLSS also has different quality modes (Quality, Balanced, Performance, Ultra Performance) that adjust the internal resolution.

NIS, on the other hand, is a simpler spatial upscaler. It does not use AI or temporal data, so it works on any GPU that supports the driver feature. The trade-off is that NIS may show more shimmering or aliasing on fine details compared to DLSS. However, NIS is more widely compatible and does not require game-specific integration.

Common Problems and Fixes

Here are some frequent issues users encounter and how to resolve them:

  • NIS option is grayed out: Ensure your GPU is supported (GTX 10-series or newer) and that you have the latest drivers installed. Also, check that you are not using an unsupported display connection (e.g., HDMI 2.0 on a 4K 120Hz TV).
  • No visible improvement in frame rate: NIS only helps if the game is GPU-bound. If you are CPU-limited, lowering the render resolution will not increase FPS. Check your CPU usage with a tool like Task Manager.
  • Blurry image: Increase the sharpness slider or lower the render resolution. Sometimes a 50% sharpness setting works best. Also, ensure the game’s own anti-aliasing is not conflicting.
  • Overlay indicator not showing: The overlay may be disabled in the Nvidia Control Panel. Re-enable it under the Image Scaling settings.
  • Game crashes with NIS enabled: Some games have issues with driver-level scaling. Try disabling NIS for that specific game and use the game’s built-in resolution scale instead.

When Should You Use NIS?

NIS is a good option in these situations:

  • Your GPU cannot maintain a smooth frame rate at native resolution.
  • You are playing a game that does not support DLSS or FSR.
  • You have a GTX-series card and cannot use DLSS.
  • You want a simple, driver-level solution that works across most games.

It is less ideal if you are very sensitive to image quality artifacts, or if your CPU is the bottleneck. In that case, lowering other graphics settings may be more effective.

Frequently Asked Questions

Does NIS work on all games?

Yes, NIS works on virtually any game that runs in fullscreen or borderless windowed mode, because it operates at the driver level. However, some games with unusual rendering pipelines may not scale correctly. It is best to test each game individually.

Is NIS the same as DLSS?

No. DLSS uses AI and Tensor cores, while NIS is a simpler spatial upscaler. DLSS generally provides better image quality, but NIS works on a wider range of GPUs and does not require game-specific integration.

Will NIS reduce input lag?

NIS itself does not directly reduce input lag, but by increasing frame rate, it can reduce the time between frames, which often results in lower perceived input lag. Nvidia also offers a separate feature called Nvidia Reflex that reduces system latency.

Can I use NIS with G-Sync?

Yes, NIS can be used alongside G-Sync. However, some users report that G-Sync may not work correctly when NIS is enabled in certain games. If you experience screen tearing, try disabling G-Sync for that game or using the borderless windowed mode.

How do I know if NIS is working?

Enable the overlay indicator in the Nvidia Control Panel. When NIS is active, a small NIS badge appears in the corner of your screen. Alternatively, you can check the frame rate difference—if you lower the render resolution and FPS increases, NIS is working.

Does NIS affect image quality?

Yes, because NIS renders at a lower internal resolution, there is a loss of detail compared to native resolution. The sharpening filter helps mitigate this, but you may still notice slight blurriness or aliasing, especially on fine textures or thin objects.
