Please show off what crt shaders can do!

crt-consumer slang with some crazy contrast, glow and brighten dark pixels

Hi @DariusG , could you please share your settings ? I’d like to try that. A thousand thanks.

I’m starting to like Lottes. It’s subpixel-agnostic so it doesn’t care what display you’re using, and IMO the mask doesn’t suffer as much when using bloom and various brightness effects. It’s not an “accurate” CRT mask but it has the feel of a good medium TVL slot mask, like an arcade monitor. Here I’ve taken my preset from my previous post and cranked up the mask strength and brightness boosts a bit more.

Contrast makes everything look sexy

Thanks for sharing, maybe I need to lower the Glow a bit, but it’s not bad, on the contrary, it’s also extremely light as a shader. I’ll do some testing soon.

If you want you can also check out this thread, it’s pretty much the “crt-consumer” thread. I like this shader as well so I made my own little preset for it. It’s for the glsl version though

Something weird is happening to the scanlines in the highlights

try this

shaders = "1"
shader0 = "shaders_slang/crt/shaders/crt-consumer.slang"
filter_linear0 = "true"
wrap_mode0 = "clamp_to_border"
mipmap_input0 = "false"
alias0 = ""
float_framebuffer0 = "false"
srgb_framebuffer0 = "false"
blurx = "1.000000"
blury = "-0.100000"
smoothness = "200.000000"
scanlow = "4.000000"
scanhigh = "6.000000"
beamlow = "1.800000"
beamhigh = "1.499999"
brightboost1 = "1.200000"
MaskDark = "0.100000"
MaskLight = "1.300000"
slotwidth = "3.000000"
glow = "0.050000"
Size = "3.000001"
sat = "0.950000"
contrast = "1.300000"

Thank you ! Really great with these settings!

I tried to change the gamma out to 2.40 to make everything a little brighter, what do you think?

Is the curvature causing the scanlines to be different widths over the same color?

For what it weighs, this CRT-Consumer is really an excellent shaders, I have to learn how to use it. In the meantime, thank you very much for your pre-settings, they are excellent and are an excellent starting point. If you have any other experiments, please share them. Thank you with all my heart.

Personally I prefer the lower gamma. I get that a lot of people just want “MOAR brightness” but this comes at the expense of color saturation and clipping, which to my eyes looks worse.

Mine are tests with the smartphone, I have to test on the screen. Surely the conception of greater luminosity is not correct, perhaps I’m getting old but I’m looking for greater luminosity and color vivacity also so as not to strain my eyes.

You might try running your presets through 240p Test Suite to check if everything is in range. Color bars and gray ramp are your friend. Other things to look for are scanline/mask artifacts caused by scaling, excessive bloom etc, although not everyone is as picky about such things.

How does this test work? I’m ignorant on the subject :frowning:

I brought the Contrast to 1.00 and the Glow to 0.10

It’s a test rom. More info and downloads can be found here:

Thanks Sonkun, very kind.

Be careful of over tweaking and over thinking, sometimes you can get it then lose it…I find Dhalsim looks a bit pale in this pic and it’s looking like there’s a slight haze over the “screen”. In addition to that, that’s way too much 2D curvature. The power bars look really warped. These are just my opinions.
