Your new/revised version of that shader.
Comparisons:
Old vs New (default settings)
Magnified point of interest
Much better anti-ringing in your revised shader. Only real "loss" of Image Quality is from the less prevalent black ringing/haloing, but this is just my opinion.
To illustrate my thought, let's take the New and Old versions and call them 0% and 100% respectively, I think having anti-ringing kick in at some point around like 20-25% would be nice. I think the "black" it adds to pixels where it happens helps define detail (like an unsharp mask?)
Either way the quality is all subjective so just go with your preference (it's your shader after all )
And the difference is so subtle I don't think anyone would notice the difference without any magnification for pixel inspection.
And another set of comparisons (my previously mentioned settings) to see how it works outside of default settings:
Old vs New (my settings)
Magnified point of interest, again
As for performance, I can't tell any difference (1 frame), but I'm being lazy because I don't think it could possibly be a substantial difference. I don't feel like logging my fps over 30 minutes at the same screen and comparing the average for this when I could be playing with my shader sliders
And Cheers again for the shader, Hyllian.
Oops, almost forgot.
I didn't check either shader in two-pass mode (3rd pass disabled).
But I did toggle it just to see how much quality is lost without that 3rd pass and noted the performance without said third pass is significantly better.
If given the choice between jinc2-sharper@default or this shader@2-pass+default, I think I'd opt for jinc2-sharper, but like I said I've not really checked it out without 3rd pass (dat quality doe!)
Thanks for the comparisons.
So, the new downscaler is better and even faster.
The 2-pass one needs some adjust to have good quality. The problem is that it is a bit shifted in right-up direction and it destroys spatial synchronization with super-res. I need to investigate it.
EDIT: I've changed a bit the 2-pass version ans now it's much better. The advantage of only two pass is performance. Here's a second version:
