Apart from the new DLSS available on NVIDIA's RTX cards, it has been a very long time since we looked at anti-aliasing implementations and the effects your choice has on performance and visual quality.  You are likely familiar with the four most common implementations, dating back to AMD's MLAA and NVIDIA's FXAA which are not used in new generation games to TAA/TXAA and SMAA but when was the last time you refreshed your memory on what they actually do and how they compare.

Not only did Overclockers Club looking into those, they discuss some of the other attempted implementations as well as sampling types that lie behind these technologies.  Check out their deep dive here.

"One setting present in many if not all modern PC games that can dramatically impact performance and quality is anti-aliasing and, to be honest, I never really understood how it works. Sure we have the general idea that super-sampling is in effect running at a higher resolution and then downscaling, but then what is multi-sampling? How do post-processing methods work, like the very common FXAA and often favored SMAA?"
