This means it uses previous frames rendered in combination with the current to reduce the aliasing in the frame itself.įXAA as portrayed in the Unity asset store Temporal Anti-Aliasing (TAA) ![]() It achieves this by combining temporal and spatial techniques. ![]() MFAA is an Nvidia anti-aliasing technique that aims to improve upon the MSAA. It only looks at the edges of a rendered object with multiple samples used to determine the color to use when downscaled. It optimizes on supersample anti-aliasing by only performing the necessary computation where it matters. MSAA is one of the more common AA types out there and is a balance between quality and performance. Also leads to a much smoother transition between the lines of pixels. When the image is downscaled is what is used to show off what the pixel roughly should look like. There are multiple scaling options that will increase the size of the upscaled image to use, with which comes a bigger performance cost.ĭuring this scaling, the pixel colors are taken to work out the average color. The way this type of anti-aliasing works is by making your GPU render a game in a higher resolution which it then downsamples. SSAA is an extremely efficient way of combatting the jagged effect and was the first available, but it is highly demanding. Let’s have a look at the different AA types and see how they work. The different types of anti-aliasingĪlthough the end result is the same with the various anti-aliasing types, which one you pick is largely down to your system’s hardware. Or why using a higher more demanding type will lower your framerate. This is why, on a lower-end type of AA, you may sometimes notice that your game is a little bit blurry. There are a few different types of anti-aliasing techniques with varied performance impacts. This blended effect does come at the cost of computing power and can often lower your FPS, especially if you have a lower-end build. The post-processing filter or render technique reduces the aliasing effect on the images by essentially blending the colors at the edge, creating a smooth illusion. To combat this staircase effect we see on every slanted or round image, anti-aliasing is utilized. Unlike in the real world where we have rounded objects, the reason we get these jagged edges, also known as jaggies, in the first place is down to the fact that everything we view on our monitor is in the form of pixels, which are, of course, square. Anti-aliasing aims to remove those jagged step-like edges from your game which we sometimes see occurring when playing in lower graphical settings.
