At Eurographics 2020 virtual conference, Lei Yang did a presentation of the Survey of Temporal Antialiasing Techniques report which included a good overview of TAA and temporal upsampling, its issues and future research.
I have taken some notes while watching it and I am sharing them here in case anyone finds them useful.
AMD recently released a great presentation on RDNA, with a lot of details on the new GPU architecture and optimisation advice.
While watching it I took some notes (like you do in real conferences) and I am sharing them here in case anyone finds them useful. They can be used as a TLDR but I actively encourage you to watch the presentation as well, some parts won’t make much sense without it. I have added some extra notes of my own in brackets  as well.
