Please show off what crt shaders can do!

Now I’m just trying to see how much bloom I can get away with without clipping.

Those look really nice and vibrant, even without any backlight boosting :slight_smile:

They do indeed! A tad too warm as well :stuck_out_tongue:

Thanks :smiley: Of course, I still think they look best with the backlight cranked up :wink:

I’m pretty happy with these results but I’m still trying to figure out why the black level seems low and how to deal with that. I tried 2.00 for dark pixel BB and it’s still not quite bright enough; higher than that and I started to clip whites. I might need to raise CRT gamma to compensate. GDV gamma can’t be raised further without crushing blacks. I might need to lower GDV gamma a bit but then I’m also reducing brightness.

Or maybe black level is fine and/or this is display-dependent? Can either of you confirm if the inner bars on the PLUGE are visible in the above shot? (should be barely visible in a dark room since this is the lowest possible intensity for sRGB IIRC).

@Squalo I agree that these shots look too warm at 6500K, but they look pretty damn good on my iPhone (if I do say so myself), which I think is closer to 7500K or something. So, maybe try that. 9300K always looks a bit weird to me, probably because I’m usually looking at 6500K.

Yes, I confirm I can see all the shades of black. That depends more on calibration than display tech.

D93 is too cool for me, I don’t like it very much. Blue can clip and red turns magenta. D75-D80 is the sweet spot range in my eyes. I almost always use D79 and then color mangle a bit on top of that.

Thanks! I guess I don’t need to do anything else to it, then. I think bloom can go even higher without clipping, but it starts to look pretty bad IMO.

I agree, 7500K - 8000K is the sweet spot for (most) retro gaming. I should probably start using that for my screenshots.

@Nesguy What kind of TV’s or display are you guys using for emulation?

Mostly crappy ones, lol. I plan on upgrading in the next 2-3 years, I just have other priorities right now.

If you’re looking for a new display, I think the high-end QLEDs from Samsung are probably the best option for brightness, refresh rates and input lag.

I’m just curious your reference point is. I see most everything on a lcd 4k lenovo yoga laptop. I don’t get much of a chance to hook it up to my oled LG.

I don’t have access to 4K, all the displays I’ve used recently are 1080p. Whatever display I’m using, I usually max out the backlight when doing CRT emulation.

Reference for point a good emulation tv?

Just wanted to be sure we using similar modern TV technology to look at these screenshots. I’m curious if the new HDMI 2.1 in the 3000 gpu’s will make things look better when outputting LG Oleds.

you can get lower latency with 120hz @ 4K.

Yeah, if anything 4K will just make everything look better. I still like 1080p because 1080p displays are cheap and so is the hardware needed to run shaders at 1080p.

One thing to be aware of: at 4K you need to use different subpixel masks than those used for 1080p if you want to keep the TVL low. I think they’re all in the shader mega-function. There are comments explaining which masks work best at various resolutions, it’s pretty handy.

@Nesguy Yes. I’ve found I like masks much more in 4k vs 1080. The subtle fidelity of them holds up better. I like when shaders having scaling for them. While not physically correct sometimes a mask looks better just a little bit smaller or larger depending on the 4k resolution and screen size.

I wanted to see if I could push the venom shader closer to the blurry dot mess or Royale. Here is my current attempt with Shadow Dancer or the Genesis. (I’m using Nesguy’s suggest 0 or 7 on mask type, In this case 7.)

Looks awesome Boom. So you where talking about that when you said blurry dot mess lol, I thought you were talking about how the bloom looked originally.

Yeah I really prefer the mask in the GDV shot to the one in the Royale shot if we’re talking about actually playing a game; that Royale mask only looks good in screenshots IMO. Did you already check contrast, black level etc?

Also, why 1313 pixels for the horizontal resolution instead of 1494?

The gdv shot looks alot more natural/organic in comparison to the royale shot imho.

@Nesguy It’s a crop down from roughly 3840x2160. Resizing such fine details either after taking a screen shot or as thumbnails doesn’t display how I’m seeing it. The contrast and blacks could be improved if I killed the glow or nudged the gamma one way or another. Nothing is being harshly clipped on either end. I tried to maximize how big and small the scanlines could get so the whole thing is probably a little too much.

Here is an interesting crop from Defender from my adjusted Venom and a near default one. Crazy the different shapes you can get with the same shader.
