Koko-aio shader discussions and updates

Perfect indeed, now I can choose the “old TV” style for all content with your two NTSC FXAA presets. Perfect and thank you.

I have one last request to make, when and if possible, it would make me even happier. Please, could you create a Smooth variant of your FXAA monitor preset in the future? I like having more options, I love how these presets turned out, and you’d be better at finding the right visual balance than me. In the meantime I have tried both your Presto TV -ntsc-fxaa and they are perfect. A thousand thanks.

I understand, but I’d prefer to not pollute preset list for simple variations like blur settings.

Just make your own, just slide 2 parameters :wink:

Ah, as a side note, i’m going to lower input gain from 1.60 to 1.40 on those 2 presets, since they seem to clip a bit.

I understand, besides the Sharp-X what value did you mean as a “switch” to increase the image blur on that preset? Thanks and I’ll immediately try to do other experiments, maybe then I’ll share the results here for a more authoritative opinion. P.S. by putting that value at + 1.00 I still get a result of blur, something that referred to the gauss. Could you help me understand this mechanism better? Thank you

There is docs-ng.md in the shader directory with extensive documentation i keep updated:

    Sharpness (horizontal, vertical):
        Modulates the sharpness of the image.
        - Max (actually 7.0) will not alter the image sharpness.
        - More than 0: will use gauss blur
        - Less than 0: will use box blur and will progressively
          add visual sharpness to image when approaching lower values.

I just made it cleared.

I’m making a lot of attempts but I can’t find a valid visual solution and I don’t want to break your work. Maybe I’m starting to believe that since FXAA already does a job of blending the pixels, looking for a smooth effect breaks a certain balance. I’ll leave it as it is already perfect, however there are your TV presets and after the modification you made they are perfect. Thank you so much always for what you do

Just made a quick test on my phone. That ambilight blends in so nice with the gb pocket

Thanks. just a quick question, do the overlay presets display properly in your phone?

Asking because RA on Android seems to have issues with jpg loading.

The pocket ones don’t seem to work and the mono ones are glitchy. They look the same in portrait mode

Thanks, I was expecting that; just fixed overlay presets btw.

Some shots of PlayStation games with your TV preset, the incredible beauty and lightness of your work leaves me amazed, consider that they are taken from smartphones with a fixed 60 fps. A wonderful magic.

Finally found a workaround to load jpgs in retroarch for android without glitches, it turns out it doesn’t like blacks, so rise them a bit:

All overlay presets updated and working on my phone, yay!

Better and better, thank you so much for your tireless work!

Using those masks on a phone is a bold move! Any chance you have a pair of decent second hand eyes to give away?

hahahaha and yet I found them beautiful, even if it’s actually true, on my 24 inch it’s a different story. However, everything was born as a benchmark, and the lightness of your work continues to leave me surprised every time I see it. With other shaders I am unable to play PSX on my current phone.

A question: do you think your “Monitor FXAA” preset is also suitable for emulating Computer Amiga or MS-Dos? I would also like to dedicate myself and emulate these machines.

The question arises from the fact that I discovered that PC monitors use a sort of double scan line on Dos contents, although it may not be useful given that your presets use FXAA which in itself smoothes out the image.

I emulate Amiga without issues, it is a bit higher in gpu use because uae core defaults to double the X resolution, but you can rever that in the core settings.

Ms-Dos, on the other side uses 31Khz monitors; as I remember there were no visible scanlines and the image was damn sharp and blocky, so if you want to recreate that look, then a simple rgb-mask without scanlines nor fxaa, nor any smooth is the way to go.

Got it, thanks so much for your advice!

I wanted to ask if there is a way to use the Generic-Handheld-RGB shader without integer scaling. When I turn integer scaling off in the shader settings it will make a weird pattern on the mask.
