How to make your PC’s graphics less blurry with Radeon image sharpness
Have you ever had the feeling that your games seem a little blurry, even if you are running them in high resolution? Or maybe you don’t have the graphics power to run them at high resolution so you are forced to switch to blurry graphics. AMD’s Radeon Image Sharpening is designed to help, giving your images a crisp look without overloading your hardware.
What is Radeon Image Sharpness?
Radeon Image Sharpening is one of those rare technical features that does exactly what it looks like – it sharpens the images in your games.
Say you’re gaming on a high-resolution screen, like a 4K TV, but you don’t have a graphics card that can push that many pixels into your favorite titles. Or maybe you have a game whose anti-aliasing implementation adds a little too much blur to the image, even at native resolution. Some games have built-in sharpening features to handle this, but many don’t.
Radeon Image Sharpening is a post-processing technique designed to make these games look sharper without slowing down performance – in fact, there’s hardly any drop in performance to talk about. Best of all, your games don’t have to specifically support the technology. It’s available in your graphics card settings and works with any game that uses DirectX 11, DirectX 12, or Vulkan (and in some cases, even DirectX 9).
It’s not just a brute force sharpening filter. It uses an Adaptive Contrast Sharpness (CAS) algorithm that emphasizes soft edges, without overemphasizing high contrast parts of the image. By using this smarter, contrast-aware approach, AMD is able to reduce the number of artifacts you’ll see with a wider application of sharpening, as you might apply in a basic photo-editing program (although that some artifacts may still appear from time to time). The results are surprisingly good, although it depends on the game and what specs you are hoping to achieve.
Radeon Image Sharpening vs. Nvidia DLSS
If you think RIS looks a lot like Nvidia’s DLSS, you’re sort of right: they have somewhat similar goals, but use different methods to achieve them.
Although Radeon Image Sharpening has intelligence built into its algorithm, it is still just a simple post-processing trick: it takes an image at a certain resolution, adds some sharpness, and spits the new image out at the same time. same resolution. Nvidia actually has a similar feature called Image Sharpening, available directly in the Nvidia control panel or through Nvidia Freestyle. This is a more equivalent comparison than DLSS.
This is because DLSS goes beyond simple picture sharpness. Instead of just applying a filter to the image, DLSS uses artificial intelligence to take a low-resolution image and reconstruct it at a higher resolution. DLSS 2.0 uses a sharpness filter as part of this process, but it’s much more than that, which means it can produce better results – at least in some cases – and has more room to improvement as it evolves. However, this is a bit more successful in terms of performance, and developers need to build DLSS support into games before they can use it.
While Radeon’s image sharpness is built into some titles (like Shadow of the Tomb Raider and Death Stranding), users with an AMD card can apply it to driver-level games for support. much more extensive.
AMD has its own DLSS competitor on the horizon, called FidelityFX Super Resolution, but it has yet to launch. When this is the case, comparing the solutions of the two companies will be a little more apples than apples. For now, Radeon Image Sharpening is a decent workaround for owners of AMD graphics cards.
How to activate Radeon image sharpening
To use Radeon Image Sharpening, you will need an AMD Radeon RX 470 or better, although game support differs a bit by card. Most cards currently support sharpening for DirectX 11, DirectX 12, and Vulkan based games, with some cards also supporting DirectX 9 games.

Right click on the Radeon software icon in the system tray to open your Radeon settings. Go to the Games tab, select the game you want to play, then activate Radeon Image Sharpening. You’ll see a slider appear that lets you fine-tune the level of sharpness you want, which can help alleviate artifacts or other issues that some games may exhibit more than others.
You may have to go through some trial and error to find your ideal setting for each game. You can also click Global Settings on the main Game tab to enable sharpening on all supported games, but it is probably best. to do it game by game so that you can adjust the slider accordingly.
If your game incorporates AMD sharpening technology, you’ll usually find it listed as FidelityFX CAS in the game’s settings. AMD recommends enabling only one of these features at a time to avoid over-sharpening. If you are an Nvidia owner, you can try out AMD’s technology using this in-game setting without having to purchase an AMD card first.
From there, simply launch the game in question, set your resolution or scaling to meet your desired performance goals, and start playing. The higher the resolution you can run before sharpening, the better. Keep in mind that RIS doesn’t enhance games at a higher resolution, it just increases blur to existing specs. The more data it has to use, the better the final image will be.
