Although this method makes TAA achieve a result comparable to supersampling, the technique inevitably causes ghosting and blurriness to the image.
[1] Prior to the development of TAA, MSAA was the dominant anti-aliasing technique.
In parts of the picture without motion, TAA effectively computes MSAA over multiple frames, but does not always achieve the same quality as the latter.
[opinion] TAA and FXAA both sample each pixel only once per frame, but FXAA does not take into account pixels sampled in past frames, so FXAA is simpler and faster but can not achieve the same image quality as MSAA [opinion]or TAA[opinion].
Possible methods include: Nvidia's DLSS operates on similar principles to TAA.
