Anisotropic FXAA is a form of texture filtering that improves an image's appearance quality. Using this type of filtering, textures are sharpened, resulting in a better-looking presentation. Meanwhile, antialiasing techniques like FXAA and TXAA eliminate jagged edges from rendered images and smooth them out for a more natural-looking result. However, it is important to note that not every technique yields identical results in a degree of success - some may see more drastic improvement than others, depending on their situation. Nevertheless, Anisotropic FXAA provides additional optimization levels and is worth taking advantage of.
