TVOut-Tweaks combined with GDV would make my GPU buckle like it does

@GPDP1

I thought, then, wouldn’t it be ideal to preserve the quality of the colors while still blending dithering in a way that doesn’t result in pixels being blended that shouldn’t be? This does mean a certain level of horizontal blurring, but it can be minimized. Blur just enough to blend the pixels and no more, is what I’m thinking.

You can take a look in your Video—>Filters and look for:

Blargg_NTSC_SNES_Custom_pseudo_MD_Composite.filt

Or

Blargg_NTSC_SNES_Custom_pseudo_MD_S-Video.filt

I think you might like what they can do as well as the performance.

There are even newer and sharper filter presets which blend the Sonic Waterfalls properly available in my CyberLab Custom Blargg Video Filter Preset Pack.

@nfp0 All of these examples use my Blargg_NTSC_Genesis_S-Video_CyberLab_Special_Edition_II video filter preset. Tap on image then zoom in for best viewing. Desktop users, right click then Open in New Tab, then press F11 for FullScreen. Non 4K users, zoom in until it looks correct.

Yeah, one of the things I noticed about shaders that blend dithering is, in the case of NTSC shaders, the colors suffer as a result due to color bleed and general washing out, whereas dedithering shaders like mdapt can result in false positives. I thought, then, wouldn’t it be ideal to preserve the quality of the colors while still blending dithering in a way that doesn’t result in pixels being blended that shouldn’t be?

Discussed here, trading accurateness for legit personal taste, maybe it suits yours as well

A large update. Using lanczos fast, color controls, ossc and slot mask

Testing another 1080p settings, mask 6, improved image…

[kokoko3k]

I am damned.

There was a time I liked those masks type very much at 1080p, then something switched into my brain and I started to spot a disturbing pattern all over the image when displaying wide solid colors, oh well, not too bad; then I started to pay attention to that pattern and I started to see it even on smaller areas, then my hunt for different/fake slotmasks started…

It is not even easy to show it to others, because as soon as I zoom the image or paint arrows over it to highlight it, it fades away lol.

I want to spare you from that, so I will not even try to describe it.

Btw if I zoom your preset it looks very good, at least

[Hari-82]

@kokoko3k yes same here I can “see” patterns on 1080p so I tend to use some form/level of shadowmask or use some “light” slotmask but only without scanlines.

My neverending quest of trying to replicate that organic phosphorus glow from the crt

[RetroGames4K]

Looks good which setting are you using?

[RetroGames4K]

[RetroGames4K]

I enhanced 4k version a bit.

[ROBMARK85]

Hi RetroGames4k, these 1080p screenshots look great, I assume you use Mega Bezel Advance, could you please share the setup you use? A thousand thanks

[RetroGames4K]

Thank you . The 1080p screenshots are from retroarch in the mobile phone. The shader I’m using is CRT Guest Advanced. I’m not at home right now, I’ll will make a few more tweaks and I’ll share it if I can tonight.

[baelog]

Is my preset I use with every console, trying to emulate the RF connection and the glow.

Looks good with higher PPI, like my tablet (has 343ppi), but on my PC its a bit blurry (107ppi).

Not sure if I can share the file here:

CRTglow.slangp

[RetroGames4K]

Thank you very much, I’ll give it a try

Here you are, My 1080p settings. This is for mobile phone, but I assume it works the same with PC… Enjoy

Very nice, can’t test it on PC roght now, but will do ASAP.

Thank you very much, very kind
