Personally, I hope it’s before Christmas 2019. That’s as close this feature would ever come to being commited before a Christmas.

We will wait for the big Christmas present.

It'd be good that they're the same. Anyway thanks for the links!

Hmm, you lost me there. I was under the strong impression those files are a whole. Like fxh being "headers" for fx. In fact, if I remove the fxh only, reShades starts with an arror: "failed to compile" and SMAA becomes unavailable.. maybe is not "another implementation" just that the library (fxh) is made by "iryoku.com" people and the calls by reShade.... just guessing.

I can suggest to add a new tab (like "Advanced Graphics"), if we can't increase the size of options window. If it was accepted, it'll be mostly about low level problems, like Intel crashes, backward compatibility. Because the Graphics Room is more low level oriented.

As far as I see reShade has own modification (or implementation) of the SMAA: https://github.com/crosire/reshade-shaders/blob/master/Shaders/SMAA.fx But the original one is present there as well: https://github.com/crosire/reshade-shaders/blob/master/Shaders/SMAA.fxh  

Please note that individual shaders for reShade are written by third parties. SMAA authors and a trove of information can be found here: http://www.iryoku.com/smaa/  This might be also worth looking at: http://mrhaandi.blogspot.com/p/injectsmaa.html (adds "Subpixel Morphological Antialiasing" to an application) Also mailed them a link to this post.. ;)
