This can make smooth transitions, which can look great in games with moving foliage. Be wary, though, because it demands a higher level of performance from your computer. Games that were released in or earlier look great using this anti-aliasing method. This anti-aliasing method, just like the TXAA, is a filtering technique that occurs post-processing.
Using color data, it actively looks for the jagged edges in images through the differences among the pixels. It is much more efficient at balancing quality and performance as it only uses what is necessary. The downside to this method is that it can sometimes be faulty when it comes to blending, mixing up background and foreground portions of the overall image, sometimes resulting in distorted text.
This is the oldest, most basic method of anti-aliasing and from which every other method has evolved. It is also the most effective method by far, but be warned. This will take up a lot of memory on your computer, so you better have the right equipment for it. The reason behind that is that it takes each individual pixel and analyzes its color and that of the pixels surrounding it.
SSAA works by rendering your game graphics at a higher resolution and then it downsamples — AKA shrinks — the image to adapt to that resolution, hence the image becomes sharper.
The FXAA method, as you might have guessed from its name alone, is a faster and more demanding technique of anti-aliasing. The great thing about this is that it processes all of the pixels on the screen, smoothing all of their edges. You get a pretty obvious decline in the amount of aliasing in your images but it would cost you — a lot. Yes, it is. Depending on your computer setup and the types of games that you play, the answer may vary. It has become somewhat outdated after the appearance of the newer anti-aliasing techniques.
A word of caution, though, and I cannot emphasize this enough: SSAA is a daunting method of anti-aliasing that can easily cut your PCs performance down by a third of its original value. So, a middle ground, then. Yup, the game crashed. Some are more efficient than the others, but usually also come at a higher performance cost resulting in FPS Frames Per Second drop. Alternatively, the second group of AA types blurs the rough edges on the screen after the rendering process. So, if you can afford to sacrifice performance for the picture quality, you will likely opt for some sort of sampling anti-aliasing.
If every frame per second is precious to you, then you will have to settle for a post-processing AA, which may slightly blur the image, but at least it will eliminate the unpleasant staircase effect.
A more popular AA is the MSAA Multi-Sample Anti-Aliasing , which only applies the sampling to the edges, where it is most needed, and will thus save you the performance cost while still noticeably improving the image quality. As previously described, enabling this will blur out the annoying jaggies with the minimal performance cost. Basically, it works like FXAA but also detects the edges to smooth them out specifically. However, as you might have guessed, this results in heavily blurred edges in the game, usually more so than with FXAA.
However, TXAA is quite demanding on the hardware and, sadly, not that many games use it in Finally, we have DLSS. This results in a noticeable FPS drop that can really make the gameplay experience less enjoyable on weaker PCs. In any case, the question of which anti-aliasing technique you should use largely depends on your hardware and personal preferences. Samuel is GamingScan's editor-in-chief.
