i never saw a picture where anti ring even at 1.0 would harm the picture. i totally love it!

anti aliasing can create out of place pixels when set over 0.30. i'm not a huge fan of it.

finesharp:

i don't like the results of it. it is simply not neutral on my test even at weak strength.

lumasharpen:

lumasharpen can create ringing/holoing when the radius is over 1.0. but i think it is very useful at radius 1.0.

i currently use these settings upscale refinement:

LumaSharpen:

S=0.70 C=0.035 R=1.0 no limiter

SuperRes
