Anti Aliasing is the method to breakdown Staircase effect or jaggies that appear in pc games.The images on your PC Monitor display are formed by thousands of small squares called “pixels.” Each pixel is a single color. Every image that’s displayed on your computer screen is a mosaic that’s made from thousands of colored pixels.

It’s easy to create images that have vertical or horizontal lines because the square pixels line up perfectly when they’re placed side by side.

But it’s more difficult to create images that have curves and diagonal lines. To create diagonal lines, the pixels have to be aligned point to point, which reveals their jagged edges. The official term for this distortion is “aliasing,” but most gamers know it as “jaggies” or “the staircase effect.”

To understand about anti-aliasing, you need basic knowledge about Display resolutions

Display resolution means number of pixels is used to create image. A Good Monitor generally has higher resolution like 1920 x 1080. In 1980 x 1080((1900 pixels on the horizontal axis and 1080 pixels on the vertical axis).

Higher Resolution means better image because they utilze more pixels and also means better color that also means more details in the image.

Different Types of Anti Aliasing

Their are many types of Anti Aliasing, But we only lists most common types

  • SSAA
  • MSAA
  • FXAA


SSAA is short for “supersampling anti-aliasing,” and it is one of the most basic and demanding anti-aliasing techniques you will encounter. Essentially, SSAA renders the game at a higher resolution and then downsamples it to produce a sharper, clearer image using various downsampling patterns.

SSAA tends to produce the best results when it comes to reducing aliasing. Still, as you might have guessed, it delivers a big performance hit that can greatly limit the performance of many GPUs, something that makes it a poor choice for those with weaker or dated graphics cards.


MSAA short for “multisample anti-aliasing,” and it is among the most common types of anti-aliasing. It generally strikes the best balance between visual fidelity and performance.

What this type of anti-aliasing does is it uses multiple “samples” of two or more adjacent pixels to create a higher-fidelity image. The more samples it uses, the better the image will look. However, using more samples inevitably requires more GPU power, and MSAA can usually use two, four or eight samples.


FXAA, short for “fast approximate anti-aliasing,” was created by Nvidia, and it is probably the best anti-aliasing method for low-end PCs. This is because it’s not very demanding on the GPU since it smooths out the 2D image as it appears on-screen rather than taking into account the 3D geometry of the in-game models.

The downside is that the edges and the textures can become somewhat blurred, which obviously doesn’t look as good as the comparably sharper and crisper image produced by MSAA or SSAA.

Should You Use Anti-Aliasing Technique?

The answer is Yes, if you want smooth images without jaggies Otherwise no if you want better performance
