What Is Nvidia Image Scaling?

What exactly is Nvidia's image scaling feature and do you need it? Here's the ultimate guide to help you understand it better.

Since the introduction of AI upscaling technologies such as DLSS (Deep-learning super sampling) from Nvidia and FSR (FidelityFX super-resolution) from AMD, getting more FPS is easier than ever. By enabling one setting in-game, users get an AI upscaled image that decreases GPU demand and increases FPS.

However, DLSS and FSR are exclusively backed by some GPU series, not every single one. Moreover, these advancements necessitate manual inclusion in each game, thus industry-wide acceptance is still pending.

Fortunately, Nvidia has a different solution called Nvidia Image Scaling (NIS).

If you desire to comprehend what it is, how it functions, and how to utilize it on your PC, proceed with reading.

Let’s dive right into it!

How Does Nvidia Image Scaling Work

Unlike DLSS, Nvidia Image Scaling is a driver-based upscaling feature, and it doesn’t use AI or any other fancy stuff like Tensor core. Instead, it uses a combination of sharpening and an upscaling algorithm.

This feature that takes the image from a smaller input resolution and with directional upscaling and a bit of sharpening outputs an image that seems to be of higher resolution, ultimately boosting in-game FPS.

Until now, this characteristic has not been used regularly, but as of November 2021, this image-enhancing technology has been updated to use a so-called 6-tap filter with four directional scaling, as explained in Nvidia’s blog post. Supposedly this new update will bring a superior FPS boost at a lower cost on quality.

How To Enable Nvidia Image Scaling

You will need to enable Nvidia Image Scaling first before using it in-game.

Here’s how:

  1. Right-click on an empty space on your desktop and select Nvidia Control Panel.
    selecting NVIDIA Control Panel
  2. Once the Control Panel is open, head over to Manage 3D Settings on the menu on the left.
  3. In front of you should be a list of settings. Look for Image Sharpening (the first one).
  4. Click it, and in the newly opened window, select On.
  5. Additionally, you can play around with the Sharpening and Ignore Film Grain filters to optimize your in-game visuals.

After enabling NIS, several input resolutions will be generated that you will need to apply in-game to utilize the benefits of this feature.

Here is a table of the resolutions produced from the provided input resolution:

ScalingInput Resolution for 4K OutputInput Resolution for 1440p OutputInput Resolution for 1080p Output
85%3264 x 18362176 x 12241632 x 918
77%2954 x 16621970 x 11081477 x 831
67%2560 x 14401706 x 9601280 x 720
59%2259 x 12711506 x 8471129 x 635
50%1920 x 10801280 x 720Not supported by Windows

So, if you’re on 1080p and use the 1632 x 918 resolution, you will get the clearest image and the lowest boost in FPS. On the other hand, if you use 1129 x 635, the image quality won’t be as high, but you will get a considerable boost in framerate.

How To Use NIS In-Game

NIS is enabled, so it’s time to use it in-game.

Here’s how you can do that:

  1. Start any game (we used God of War).
    God of War settings
  2. Go into the game’s settings and into the Video/Display/Graphics options.
  3. Change Display Mode to Fullscreen (or Windowed).
  4. Select one of the newly generated resolutions (table above).
  5. Once selected, hit Apply (if required) and enjoy your game!
    selecting resolution

That’s it! You’ll now have more FPS in your game while image quality has been maintained.

Reminder: It’s not advised to utilize NIS if your graphics card can employ DLSS or FSR, as they are superior choices. God of War is already equipped with both DLSS and FSR.

Also, remember that not all games may have an option for Fullscreen, so you won’t be able to use NIS.

Below is a comparison of NIS at 85% resizing (1632 x 918) and NIS deactivated (native 1080p).

The difference in quality is definitely noticeable, especially if you take a closer look at Kratos’ armor or axe. However, NIS 85% still looks pretty good while also getting 10% to 15% more FPS.

Final Words

While NIS might not be as effective as DLSS and can over-sharpen some video games (it’s adjustable), it’s still just a simple push of a button that can provide you with a significant boost in performance.

Whenever any upscaling technology is available, we recommend you always to use it as there are minimal to no downsides.
