FXAA Supersampled for better quality?

I stumbled on this Marty McFlys post reshade.me/forum/shader-discussion/599-fxaa-ultra-quality#5153 from this forum whilst searching for the best AA solutions. Is it really possible to do this? I tried multiplying buffer_width and height by 2 in reshade.fxh, but it doesn't seem to do anything. Maybe it's simply not making any sense and that's why it doesn't work? Anyone?
Thanks in advance.

Hey Marty, thanks for your answer! Can SMAA be "downsampled" or the idea of downsampling AA shaders is just moot?Marty McFly wrote: Yeah... That didn't really work out. SMAA is better and faster.

Shame T2X isn't possible but for a generic shader injection ReShade has improved a lot since the early versions in several other areas and some things just aren't as feasible without game specific support.
And FXAA is just a blur, that certainly explains why people find it smoother looking and why it's sometimes preferred when running downsampling either through the game or through the GPU or similar software. (And why it's also so fast though still a fairly OK early post-process AA method.)

Marty McFly wrote: It can, but I think this'll make the result worse. SEE, FXAA just blurs the image where it's jaggy, SMAA tries to detect geometry edges and guesses how the geometry looked like (let's say you have 4 pixels shaped like an L in tetris, this suggests that the underlying geometry has some sort of \ line). It then modifies the pixel colors to give a perfect representation of that guessed geometry. If SMAA detects a 1 pixel wide line (for example a wire or something), the result is 100% accurate anti aliasing, just as if you ran 4x Downsampling. Raising the internal render resolution spreads each pixel into a 2x2 block so SMAA won't detect these edges anymore.
Ok, thanks for clarifying this.

What is your recommended settings for a non-shimmering experience, Marty? Because SMAA flickers a lot no matter what I do.
One more thing, what kind of SMAA is Batman Arkham Knight use? That thing is stronger than any post processing AA I have ever seen.
