A consensus can only be given for users having the exact same setup and videos usually. This being said, the consensus is that AB helps a lot and makes things better, but everyone found their own setting that works for them. I have a hard time reading the rest of the question. Super res has it's uses too, usage of AB is good for all algorithms so far.

They both do the same thing, so those shaders would be competing with each other. It is better to choose one or the other, not both.

Sure, I'm not sure if it is 100% accurate. But you can use it. I've used many of your descriptions.

sharpen edges and crisped edge (thin edges and enhance details) are not designed to work on the same part of the image so you can use them all together at the same time.

As for the second question, I don't know how to word it better. In essence, would one generally use higher strength of superres the bigger the upscaling factor or vice versa. If the answer is the classic "use your eyes", I'll just leave superres at 1 for everything and stay happy. |

The higher the upscaling factor, the less SuperRes strength you need to see a distinct effect of it.
Matter of personal taste if you want to have a stronger or weaker effect. High SuperRes strength looks less artificial than other sharpen filters, however you can get problems with aliasing, mostly when the source is bad. |

At 2x (1080p -> 2160p), I would use SuperRes (3) without anti-bloating because SuperRes really doesn't bloat all that much if the image is not oversharpened. Nor does it need anti-ringing. enhance details (1.0) is another shader that is not redundant. To me, SuperRes at the right strength provides plenty of sharpening on its own.
sharpen edges and LumaSharpen are likely pushing the image towards being oversharp and are redundant. If you like the image really sharp, I might add sharpen edges with anti-bloating but not LumaSharpen on top of that.

You're right; both are true.

So if I understood you and aufkrawall correctly:
The effect of SuperRes may be easier to spot when scaling SD -> 1080p vs. 720p -> 1080p using an identical SuperRes setting (1, 2, 3 etc.) But because of the softness of SD, a higher SuperRes setting may be required to counter the softness (but with the increased the risk of artefacts). And 720p on the other may become oversharp, so a lower setting might be more appropriate. Notice the "mays" and "mights". I do realize sharpening is about personal preference. I have sharpness turned to 0 on my Samsung TV; my eyes are sensitive to too much sharpness and start to "hurt". That's why I tend to use SuperRes at 1, use no other sharpening and direct my available resources towards NNEDI3 processing. Also when downscaling, I use lower values, mostly bicubic 75% and for UHD -> 1080p also 2D SSIM 25%. |

If rendering time is below 30ms, why not? All my content is 23 fps, so my GTX 970 can handle it. Image doubling at NNEDI3 kills performance more.

I know, but super-xbr anti-bloat 25% is good for image doubling too, and the fans on my 970 card doesn't spin up as much as they do with NNEDI3. A good compromise I think. Chroma Upscaling 128 is nice to have with 1080p movies that run 1:1 (no image scaling).
