What's TAA?
antialiasing and denoising through temporal reprojection (using data from multiple frames)
it works pretty well imo but makes things slightly blurry when the camera moves, it really depends on the person how much it bothers you
its in a lot of games because their reflections/shadows/ambient occlusion/hair rendering etc needs it, its generally cheaper than MSAA (taking multiple samples on the edges of objects), it can denoise specular reflections, and it works much more consistently than SMAA or FXAA
modern upscalers (DLSS, FSR, XeSS) basically are a more advanced form of taa, intended for upscaling, and use the ai cores built into modern gpus. They have all of the advantages (denoising, antialiasing) of taa, but also generally show blurriness in motion.
