Filters. Good? Bad? Only in 3D games?

[Anonymous No.1875548]

Not a big fan of that filter honestly. I usually don't like filters on my games because I feel that the 2-D sprites (especially in 16-bit and higher eras) generally look alright. They tend to have held up better without needing filters unlike early 3-D games which can look fucking amazing with a good filter.

I use a CRT filter when emulating. It looks so much closer to how I remember from childhood and still play the games on consoles to this day.

It's far from perfect, but it's more appealing to me than clear pixels which I'll argue is not how the artists intended the game to be seen but I realize that's a whole other debate

I find any other filters to be absolutely disgusting

I wish there was a way to make a filter that made everything less pixely without just making everything look like a round blobby mess. Impossible to do, I know, but I can dream.This is especially for handheld games, since they're often so low-res that sprites look like shifting pixels. Metroid Fusion comes to mind (hurr durr not retro)

I also tend to use scanline filters. I used to think they were shit because the old filters from like 10+ years ago just added black lines over everything, but now they actually look like what I remember

What is actually the closest filter to the original stuff?
This can't be discussed, either it's close or it's not.

[Anonymous No.1876736]

>>1876727
There is no "original stuff". The only thing close to original is what comes out of the video buffer, which gets converted to analog RGB signals and then encoded into composite or just output the way it is. You can buy some expensive capture card and connect a console through RGB, that's a close depiction of what should "original stuff" look like.

[Anonymous No.1876878]

>>1876727
Technically I think it's called "affine", meaning basically no filtering, you draw one pixel for each element in the buffer. Graphics dont necessarily need to be drawn with square pixels though, like your LCD screen. CRT TV's didn't see "pixels" at a fixed resolution; it could be an arbitrary pixel resolution that's stretched by the screen to a different aspect.

In order to display an aspect correct image, the display filter for any given emu has to do some kind of "filter" to reconstruct the image. Generally it's called nearest neighbor, a quick mathematical stretch, no blending. You'll get some distorted or oversized pixels depending on your display's max res compared to the source (more the better).

There are a few graphics filters that try to minimize the "frankenstein pixel" problem in nearest neighbor filtering. It's called Pixellize or Hardware 2x, 3x, for example in DosBox and some emus. They just try to keep the rounding error down and make as square as possible pixels.

My usual procedure is to increase the resolution by a factor of 2, then use a bilinear filter. For older games, it usually approximates the look that older, non-RGB cables could produce. But, that's as far as I go.

[Anonymous No.1876903]

>>1876727
every tv had different displays, with varying types of scanlines, blurryness, glass concavity, screen size, depending on whether you were using s-video, rgb, composite, rf cables, etc. There's no universal "authentic" filter, you just use what you think looks best.

I owned for a long time a shitty integrated graphics notbook which completely ruined and doubled the lines of anything resized in nearest neighbor, so I grew fond of playing with bilinear filtering ever since then.
Also I don't like playing in fullscreen for some reason. Feels like I'm sitting too close to tv.

[Anonymous No.1877208]

No filters are only good when you're outputting it through a display it was meant for, IE a CRT which will give a filter like effect.
Filters/shaders can be good or bad depending on which ones are used. Some create problematic artifacts with layers or lose significant detail or just plain have terrible artifacts anyway. Bilinear is generally accepted as the minimal filter. I prefer a flat cgwg CRT or NTSC filter for most things.
I'm not telling people they have to stop using raw pixels, but I will tell them the truth, it looks like dogshit with raw and it's not meant to look that flat or jagged. Anyone who disagrees with that disagrees with the fact that CRT TVs existed, which is absurd.

I'm currently 'in the middle' of trying to fix it up to have color aspect like a GBC. Not too good at the moment. However, it does the contrasty green fine like your image and I played with that for a bit and got the ghosting to go away. I also scaled my zoom to 6x instead of 4x.

That's a shader to output to crt you idiot.
The crt outputs at standard 240p and the image compresses to give it a proper aspect ratio.

That concept requires a dynamic shader that has the dimensions of your display. Also, that's not authentic because the view scale of the gameboy screen is inversely proportional to the ratio of the physical size to distance of the viewer, also any intermediary devices in between. The scale of something is wholly dependent on how one views it. In short. It already is 2.6" when you sit far enough away just like how a gameboy can fill up most of your view if you get close enough to it.

No you don't. That day doesn't exist.
That's like saying I await the day when multiplying two even numbers doesn't produce an even number. No such day exists because it's a state property. Scanlines will always make white look 'greyer' because the distance blurring of light blends and it just so happens to blend white with that pattern. Even if you were using straight scan-line separation with pure black instead of using a dimmed guassian line blend function to simulate smaller breaks than the screen. You can edit some of the filters to adjust the range of the gaussian degree of the function. It'll make it look 'whiter' but it'll still look grey in comparison to having insignificant scanlines of a typical monitor.

I use the low pass filter and 32Khz on the SNES because that's what it sounds like.

I don't put echo or reverb on any of them myself. Bass boost definitely isn't required,
The only other DSP I use is built into my audio system for converting stereo/mono to binaural with HRTF with CMSS3D - For headphones because that's what I wear. If you're using headphones you might want to use some sort of HRTF. Stereo through headphones is kind of awful.
