Difference between anti-aliasing taa and fxaa

The main differences between anti-aliasing taa and fxaa are computing power, picture quality and hardware consumption.

1. Computational power

TAA is a technology based on pixel motion between frames, which smoothes the jaggies by averaging the pixels of two adjacent frames. It can deal with relatively complex scenes, but it may appear visual blur and motion blur, which requires higher computing power. Generally speaking, FXAA is suitable for processing sawtooth in simple scenes, which can be processed quickly and reduce the burden on GPU. TAA is suitable for dealing with sawtooth in more complex scenes, which can provide higher sawtooth smoothing effect, but it needs more computing power.

2. Picture quality

FXAA is a technology based on pixel color analysis, which detects and reduces aliasing by analyzing and comparing each pixel. FXAA can quickly process a large number of pictures, but it may appear blurred and distorted when dealing with complex scenes.

3. Consuming hardware

FXAA is a fast approximate anti-aliasing with the lowest consumption. If the anti-aliasing is turned on at a low level, it is actually a rough fuzzy processing. The anti-aliasing effect of TAA is much better than that of FXAA, but it consumes more hardware.

Introduction to Anti-aliasing

Anti-aliasing is also translated as edge softening, anti-aliasing, anti-aliasing and so on. It is a technology to eliminate the jagged edges in the images output by the display. Those jagged edges are usually caused by graphic aliasing when high-resolution signals are expressed at low resolution or 3D graphic coordinates cannot be accurately calculated.

anti-aliasing technology can effectively solve these problems. It is usually used in digital signal processing, digital photography, computer graphics and digital sound effects, etc., to soften the aliased digital signals.

it is usually used in digital signal processing, digital photography, computer drawing, digital sound effects and electronic games, etc. to soften the overlapped digital signals. Anti-aliasing is a mosaic that reduces the jagged pixel grid on the edge of game graphics and makes the picture look finer instead of full screen. The larger the value, the better the picture.
