Temporal anti-aliasing
Temporal anti-aliasing is significantly cheaper performance-wise than techniques as MSAA, yet often yields a very close level of quality. Additionally it also solves the problem of temporal aliasing, which is not solved by MSAA or other similar anti-aliasing methods. The framework already has a general purpose temporal filtering shader, it is just a matter of applying that filter to the whole scene. Currently the filter is only being used for stohastic screen-space reflections. Note that the velocity buffer is currently not set up or being written to, meaning only camera movement is accounted for - moving objects should write to the velocity buffer in order to be properly filtered.
It's always nice to have more options, but wouldn't SMAA (Subpixel Morphological AA) be preferred to TAA or FXAA in most situations?
Usually when I play games I just turn AA off unless it has SMAA or is graphically 'light' enough to use MSAA, since FXAA and TAA introduce a noticeable amount of blur.
