If anyone's interested in trying it out, I've started experimenting with a form of Temporal SMAA here:
github.com/lordbean-git/reshade-shaders/...ain/Shaders/TSMAA.fx
It performs temporal data aggregation similar to what I did with edge detection in HQAA, except for every step in the technique instead of just the edges. I also used the SMAA data to implement a form of raster artifact control similar to the optional image softener in HQAA as well as previous-frame blending to help with image stability.
This is still basically just an experiment so your mileage may vary considerably in terms of the output image quality.
