There is always one option that confuses the non-gamers, which appears in gaming graphics card settings, and that is Anti-Aliasing (AA).

Anti Aliasing technique is a term where the Graphics processor enables shadow, rounded shapes, or curved edges to make the games smoother and improves image quality as the jaggy edges make the images look roughly.

In this article, we will try to explain about anti-aliasing, its types, and which one is good for you along with some other explanations. Besides, you will get an idea to choose the right antialiasing. Briefly, even if you’re not a gamer, then you must know what it is, how it works, and what type of antialiasing setting is the best for your hardware and resolution.

What is Anti-Aliasing?

Anti Aliasing

Anti Aliasing is the method that reduces the edges of polygons to make the image texture smoother. With this, the final rendered objects jaggies are lessened, which are made using square-shaped pixels.

And, aliasing makes an image appear with jagged lines; it means the image renders using visible pixels. It makes it look rough, and before Anti Aliasing, Most of the games used this method.

In our real-world the objects that are perfectly round shaped, they are not really rounded in computer. And if you play games with a lower graphics system you will witness the prove. So why is it? Everything we see on the monitor is formed with pixels and these are of course rounded shaped. That’s why, for every rounded shape, there is formed a shaped exactly like the staircase. To make these staircase shape into a round shape rubbing or scrubbing is a must and that’s why Anti Aliasing is here.

Anti-aliasing filter

An anti-aliasing filter helps to restrict the bandwidth of a signal to approximately.

Types of Anti-Aliasing

Amid different types of antialiasing options and where all of their only goals are to improve the game’s image quality, you must choose wisely which one to choose. Let’s see which one works well and how. 

SSAA (SuperSampling AntiAliasing)

SSAA is a spatial anti-aliasing method, and it is the oldest of all AA that has an efficient way to render a higher resolution image.  As it increases the pixel density and displays smooth curves and sharper images, it needs a massive amount of PC power, and that’s why it is also demanding. Yet, it somewhat will disturb your performance. 

MSAA (MultiSampling AntiAliasing)

The term multisampling refers to a special case of supersampling optimization; it means multisample antialiasing evaluates the piece program once per pixel (single pixel). Using two or three adjacent pixels, it creates a higher fidelity photo. The more pixels you use, the better quality you get. Simply putting, this type of AA renders an image or scene at a higher resolution with important resources such as texture, shadows, bandwidth. MSAA in games is found as 2x MSAA, 4x MSAA, and 8x MSAA, and the higher one you choose, the more PC power you will need. 

CSAA (Coverage-Sampling AntiAliasing)

CSAA is a new AA technique Nvidia had introduced. Carrying almost the same feature as MSAA, it has also coverage samples that are newly added. 

FXAA (Fast Approximate AntiAliasing)

FXAA is best for low-end PC’s, and it gives good performances despite its low demanding option. It will provide you with higher performance than that of 4xMSAA, but in general, you will often find the images blurry, and they won’t look as sharp as the oned of MSAA. 

EQAA (Enhanced Quality AntiAliasing)

With a minimal performance cost, EQAA developed by AMD will smooth out the edges. Point to be noted, EQAA also features almost like MSAA, and it doesn’t affect the performance. 

TXAA (Temporal AntiAliasing)

To reduce or to remove the temporal aliasing, TXAA does a great job. It is a mix of several techniques, and through working on it, temporal antialiasing smoothes edge that is better than FXAA. Yet, you can’t still unsee the blurriness that TXAA produces. 

DLSS (Deep Learning Super Sampling)

Developed by Nvidia, DLSS is a technology that uses the power of Deep learned and trained A.I algorithm to improve the game performance and, at the same time, improving or maintaining visual effects. It uses Tensor cores and can access all RTX (Metro exodus along with the same similar limitations as RTX)

MLAA(Morphological AntiAliasing)

MLAA isn’t very demanding, most likely as FXAA. It does reduce the jaggies but it will give a blurrier image than FXAA.

SMAA (Subpixel Morphological Anti Aliasing)

Another MLAA type of Aliasing which renders similar features. But it has less blurriness than FXAA or MLAA.

Which AntiAliasing Technique is best for you?

After all the introductions, you still need to know which one to choose. Every AA is good for its purpose. Choose wisely, whether this one or that one is right.

FXAA, MLAA, and SMAA, these three renders the same quality, which are excellent choices for low-end PC’s. But, the fact mentioned before that all these three end up blurring the image that doesn’t look sharp or smooth. Yet, they are far better than those images with jagged objects.

In the term of a sharp and smooth image, the names came into our mind are SSAA and MSAA. But for this, it will require a lot of PC power which you are already aware of. Because on low-end PC or less powered PC using SSAA or MSAA will make the Framerate drop and make the gaming experience unpleasant. 

Though they are most likely the same, we’ll keep SSAA at the top as MSAA is like the middle child between SSAA and the group of those three (FXAA, MLAA, and SMAA).

SSAA > MSAA > (FXAA, MLAA, and SMAA)

Well, the rest of the techniques are the unpopular ones, but they can be used to support some games though.

Things to keep in mind-

Now, it is high time you set your mind. If you want the best performance and whether the image quality is good or bad doesn’t matter to you, then you should go with FXAA. But if you want your eyes to be mesmerized with a crispy and smooth high-quality image, even though your performance will be somewhat affected, then go for SSAA. And I know that I have made you confuse, but MSAA will be best to have both of the advantages though your opinion matters the most here.   

The resolution of your monitor is the one that impacts a lot on which technique you choose. If your monitor is of a small screen with 1080p then you won’t be noticing aliasing that much but if the monitor is large, you will notice the aliasing easily. For 4K gaming monitors, you won’t be noticing the aliasing no matter how large your screen is unless you place yourself extremely close to the screen. 

Closing thought

Now that we’ve finished our discussion, it’s up to you to make your choice. In spite of having many methods of antialiasing, we’ve tried our best to sort them out for you so that you can choose wisely and easily. Firstly, see what will be suitable for your hardware and if it could generate the power or not. Secondly, sort out your thoughts, and it will be easy for you. 

Last but not least, anything we’ve missed out or any mistake that makes you uncomfortable with our article, feel free to comment down and we’ll try our best to resolve the problem.
