The text in particular looks oversharpened with slight haloing present. Setting Freestyle to 50% sharpening, and many of the same issues crop up as with adaptive sharpen. Nvidia Freestyle to me looks most similar to Reshade's adaptive sharpen.

This crops up across the image with a lot of oversharpening, plus you get haloing.
But adaptivesharpen doesn't know, and tries to sharpen it, which just leaves this weird blocky artifacting. This is supposed to be a bit blurry as you might expect from this type of display in the game's world. Take the continue text on the CRT screen. Then we get to Reshade's adaptive sharpen, which in its default configuration is much sharper than Radeon Image Sharpening. But then for the map in the upper corner, basically that entire texture is clearer with RIS compared to lumasharpen and it's in areas like that were AMD's algorithm has a clear edge. Then for the 'New Game' texture, RIS is a slight improvement without the introduction of much haloing or artifacts. In some ways, RIS is just as subtle as lumasharpen, for example in the fibers on the sweater on the right. Radeon Image Sharpening is a clear improvement on lumasharpen. If Metro Exodus used a sharper temporal anti-aliasing method, the game with lumasharpen is probably how I'd expect it to look. It slightly sharpens the image, clears it up a bit, and doesn't introduce many artifacts. Reshade's lumasharpen in its default configuration is the most subtle of all the filters. In some respects the end result is similar for all filters, and in others there are differences. What's immediately apparent looking closely at these images is that each sharpening filter has a distinct style and each manipulates the image in a different way. We'll get started with Metro Exodus because it provides a good combination of 3D elements, textures and text. For all screenshots, you can click on them to see a larger 4K version of the same image. In addition to the image quality shots offered here you can check out Hardware Unboxed's video (embedded below) using YouTube's 4K quality for the best possible representation of the game's graphics. Image Qualityįor this new test, we want to compare Radeon Image Sharpening and AMD's CAS algorithm with several other sharpening options that are available today including Nvidia Freestyle and two popular filters available in Reshade: lumasharpen and adaptivesharpen. So now, we can see how CAS works on other GPUs, and whether AMD restricting RIS to their new Navi GPUs actually makes sense. This has been possible because CAS is included in AMD's open source FidelityFX toolkit, and it seems that porting that to a Reshade effect was quite easy. The other big new development is that AMD's Content Adaptive Sharpening (CAS) filter used in RIS has been ported to Reshade. But we'll have a look at how it stacks up in this article. Nvidia Freestyle is marketed quite differently to Radeon Image Sharpening and unlike AMD, Nvidia doesn't suggest that sharpening could be used with resolution downsampling for performance benefits. Nvidia has their own sharpening option included with their Freestyle game customization tools as well.
Reshade is a very popular tool that can be used for all sorts of post processing including sharpening through several techniques. Namely, Radeon Image Sharpening is not the only way to post process sharpen a game. With a negligible performance impact on Navi GPUs, it makes for a pretty compelling feature.īut we didn't cover every angle possible in that article. The conclusion we came to was that RIS is superior to DLSS in terms of image quality and very effective at post processing say, a game rendered at 1800p to look very close to its native 4K presentation. The big focus of the test was how RIS compared to Nvidia's DLSS, and whether the two technologies could effectively do the same thing, even though they are different in how they work.
The first article is definitely worth a read if you missed it, as we were mainly interested in seeing how Radeon Image Sharpening (RIS) looked compared to a native presentation, and how effective it was at post-processing an upscaled image to look near-native. After testing AMD's new Radeon Image Sharpening feature, we've gone back for even more testing.
