What is Anti-Aliasing and Why Is it Important for Gaming?

If you are a gamer, you might have come across the term anti-aliasing in games and the option to turn anti aliasing on or off. Are you curious about what anti-aliasing iswhat does anti aliasing do, and how it can enhance your gaming experience? In today’s post, we give you a crash course on Anti-Aliasing

If you know anything about computers and digital images, you must be aware that every image in a game is made up of pixels, which are square-shaped. However, not all objects in the game are rectangular or straight. Due to the nature of the picked, round and inclined have jagged edges, which affects the game’s visual quality.

Anti-aliasing technology is used to smooth out jagged textures and lines through a process of blending colors on the edge of the object. Typically, the jagged lines are more apparent when you play games on a low setting because Anti-Aliasing is either turned off or on low.

Let’s discuss the topic further:

How Does Anti-Aliasing Improve Gaming Experience?

As we mentioned earlier, the digital images in games are composed of square-shaped pixels that cause jagged edges in non-rectangular objects. The issue of jagged edges also occurs in high-resolution images that are made up of millions of tiny pixels because pixels are still rectangular. As a result, the jagged edge issue known as aliasing is guaranteed to happen.

Anti-Aliasing, as the name implies, is a combination of techniques that help in reducing aliasing to make objects appear smoother. There are different types of Anti-Aliasing techniques that use various methods for dealing with the jagged edges. 

What Are The Different Anti-Aliasing Types?

Thanks to technological advancement, different Anti-Aliasing types have been developed that different yield levels of results. Some techniques are more commonly used today for modern gaming, which others are being phased out because they are outdated. Let us take a look at the different anti-aliasing techniques that are popular and typically used these days.

Multi-Sampling Anti-Aliasing (MSAA)

One form of anti-aliasing is known as “multisample anti-aliasing” (MSAA). It’s the most prevalent type of anti-aliasing nowadays, balancing performance and visual fidelity.

Using multiple “samples” of at least two pixels, this form of anti-aliasing produces higher-fidelity images. The greater the number of samples, the higher the image clarity. However, it comes at the expense of needing more GPU power; fortunately, MSAA is limited to eight samples and will not extend above that.

Supersample Anti-Aliasing (SSAA)

By far, the strongest and perhaps the most effective anti-aliasing solution accessible today is Supersample Anti-Aliasing.

It causes your GPU to render games at a greater resolution before downsampling the picture. The higher resolution produces more pixels, meaning the image appears sharper. However, once again, it necessitates a high-end and robust GPU with extra video memory.

Fast Approximate Anti-Aliasing (FXAA)

FXAA is among the easiest anti-aliasing methods to use. FXAA is the way to go if you’re looking for anti-aliasing but doesn’t have or want to purchase a high-end PC.

It blurs the image’s jagged edges rather than performing all of the calculations and utilizing the GPU power, leading to a much faster with minimal performance effect on your Computer.

Temporal Anti-Aliasing (TXAA)

TXAA is a newer form of anti-aliasing that is only found in newer GPUs. It employs a number of anti-aliasing methods to smoothen out the image’s edges.

It is less demanding compared to a few other anti-aliasing techniques, but it creates higher-quality images than FXAA. However, some blurriness may still be present.

Morphological Anti-Aliasing (MLAA)

TXAA anti-aliasing smooths out edges by inspecting the variations between pixels.

Unlike TXAA, which prioritizes quality over speed, MLAA is gentle on your Computer. It is more efficient and achieves a better balance of quality and efficiency on what is required.

The disadvantage of TXAA is that it can occasionally be faulty, resulting in distorted text when combining background and foreground image sections.

Which Anti-Aliasing Technique Should You Use?

The methods that depend on post-processing, such as SMAA, FXAA, and MLAA, are a reliable option for mid and low-end builds because they reduce aliasing without consuming too much GPU processing power. However, the image quality is blurring most of the time and not as crisp clear as generated by multisampling and supersampling methods.

Although MSAA and SSAA produce cleaner and crisper image quality; however, they consume a significant amount of processing power, resulting in a noticeable FPS drop. Due to the FPS drop, the gameplay experience becomes less enjoyable on weaker PCs.

Does Anti-Aliasing Affect Fps?

Anti-aliasing puts additional load on the graphics card. If your graphics card or the computer on which the GPU is running is not powerful enough, anti-aliasing will cause a significant drop in FPS. The large amount of loss in FPS will be more visible when you play high graphic games. 

Anti-Aliasing Setting for PUBG, World of Warcraft, Valorant

The most popular anti-aliasing setting for PUBG, World of Warcraft, Valorant, and other high graphic games is the MSAA 2X and MSAA 4X. MSAA is the best setting for playing high graphic games for optimum cleanness and clarity. Remember that MSAA 2X causes a 19% frame rate dip, whereas MSAA 4X causes a 29% frame rate dip. 

For gamers with a low-end PC, MSAA is the best setting for an excellent gaming experience, with minimum impact on processing speed and frame rate. If you have a high-end PC, you can use TXAA without compromising processing speed and framerate.

Should You Disable Anti-aliasing?

In highly competitive gaming, where pixel-perfect accuracy with your shots is required, owning an acute visual monitor can give you a slight advantage over opponents. And if you’re looking for realism, you want to be focused on something other than unnatural lines or blocky textures. Anti-aliasing is helpful because it affects engagement as well as efficiency within a game, yet it additionally has a negative effect on performance by consuming computational resources.

Anti-aliasing is generally unnecessary if you’re using 4K resolution on a 27-inch display. A resolution of such a magnitude will appear smooth right away. However, anti-aliasing may be of assistance in other ways.

For instance, it may be capable of helping in the smoothing of textures and lines, which is not something that can be accomplished simply by making cells smaller.

As with many other aspects of life, the best method to determine if you require anti-aliasing is to experiment. Load up a few of your beloved games and see if you like the blending effect it creates. And if you’ve been experiencing performance problems, try turning it down or off to determine if that helps.

When searching for an anti-aliasing preset to use, keep in mind that there isn’t a single best setting. It is determined by your Computer, display, as well as the game you are playing. However, as a general rule, FXAA is a decent primary anti-aliasing option for low-end systems, and MSAA could be disabled to save resources. 

If you have a modern GPU, don’t be afraid to attempt some of the more complex letter combinations, such as CSAA. You’ll be able to make sensible decisions regarding your personal settings in the future as long as you remember that more filtering isn’t always better.

Final words

All-in-all, the anti-aliasing technique that you should select mainly depends on your GPU and personal preference. If you want the best gaming performance, then we would recommend you to select FXAA. If performance is not your preference and your top priority is the graphics’ quality, then SSAA would be an excellent choice for you.

If you are new and unsure, we recommend you to try all anti-aliasing methods to find the one that best fits your needs.
