>I can't say for sure, but what I think happens is that all the artifacts and noise gets smaller, making it easier to work with, but so do the lines, which often makes them cleaner.
makes sense.
So far every upscale I did improved in sharpness when doing the double resize. I just use 50% resize for every image and the same upscale model both times.
Since I'm currently working with high res images It takes some time to double upscale them but it's totally worth it. (From 2,429x3,200 to 19,432x25,600)
