NVIDIA
Nvidia has developed a new anti-aliasing technique it dubbed Adaptive Temporal Anti-Aliasing (ATAA). ATAA builds upon the existing Temporal Anti-Aliasing (TAA) method, but kicks things up a notch by adding adaptive ray tracing rendering techniques to the mix.
Temporal Anti-Aliasing has become one of the more popular anti-aliasing options for gamers as it produces great results in most situations without imposing a performance burden on their systems. But as with every anti-aliasing method, Temporal Anti-Aliasing is not free of drawbacks, and the principal issue is that it tends to add a considerable amount of blur to the scene. The blurriness is more noticeable than ever when there is a lot of object motion on screen. However, Nvidia has found a solution to this problem - or so it claims.
Unfortunately, it'll take some time before we see Adaptive Temporal Anti-Aliasing in games as it relies on Microsoft's DXR API, which is yet to be supported by mainstream gaming graphics cards. Nvidia has scheduled a talk about its new anti-aliasing technique at SIGGRAPH 2018, which will take place in Vancouver, British Columbia between August 12-16.
