Adaptive Shading, and it basically works as a post-process step that looks at previous frames to calculate which determine quality conditions for the next one - lowered detail areas such as skies, flat walls, or even shadowed portions of objects require lesser amounts of shading detail, and thus, their shading rates can be reduced from a per-pixel shading to four pixels per shading ratio. And this new feature, which was originally showcased on MachineGames' Wolfenstein II: The New Colossus, will finally be implemented in working form on that particular game, via a patch that's being released on November 19th. This is the first title to make use of this technology - and hopefully, it isn't the last. Should be interesting to see the differences and/or improved performance.
