- ekianjo 3y agoCrt shaders cant really replicate what CRTs actually look like.
- bni 3y agoWith HDR and OLED I think its very close
- musha68k 3y agoThey fundamentally don’t but a high quality / high refresh OLED display can come very close and if implementation done right IMHO can even surpass experience in some cases. I still play old games on my old beloved tubes but to be frank often just for purity / nostalgic reasons and because I like the original 4:3 format without (“perfect black” even) overhead on the sides. I hope Apple will finally Switch to OLED for their iPads as the aftermarket / replace displays for those usually are well affordable and usable for e.g. a wall mounted “cabinet”.
- PostOnce 3y agoWhy not, specifically?
- giantrobot 3y agoThey most certainly can but the requirements are steep. Being able to run at 4K/120Hz is where you start to get very accurate simulation of a CRT. You need a high resolution to draw the phosphors, mask, and bloom. You need the high refresh rate to be able to have realistic phosphor draw and decay.
- Tade0 3y agoTo me this is sounds like the tube vs solid state amplifier in guitars debate again. I think the question should really be: can they do a good enough job? My take is that with the right display they can. CRTs didn't have an impossible refresh rate, colour gamut, contrast or resolution - arguably they kind of suck in each of these areas compared to modern displays. I mean, we didn't see screens show deep teals until OLED arrived.
- willis936 3y agoIt's a similar argument, but as with all engineering questions the details matter. The human auditory system can be entirely fooled with 2 channels of 40 kSamp/s 16-bit data: 1.3E6 bits per second. The human visual system is much more difficult. It's hard to put a hard number on it due to the stochastic nature of "pixel" sampling in the eye, but generally 1000 Hz is accepted [1] (pulled from blurbusters). I'm also going to gloss over foveated rendering since I'm assuming a one-way "trick the system" box. The human visual system would need 2 channels of 7500 x 7500 (120 degree / 0.016 degrees per pixel) x 1000 Hz x 3x16-bit color: 2.7E12 bits per second. To get to my point: it is technologically trivial to work with audio compared to video. Audio simulation and reconstruction has been a mostly dead area of research for decades while video is still flourishing. Audio did not stop at the actual technical best place it could have, but when it was good enough and diminishing returns hit. 1. https://www.lrc.rpi.edu/programs/solidstate/assist/pdf/AR-Flicker.pdf#page=6 https://www.lrc.rpi.edu/programs/solidstate/assist/pdf/AR-Fl...

- Jensson 3y agoYes they can, I saw them in the video we are discussing, my screen showed me smooth pixels instead of blocky ones even though I don't have a CRT screen. Of course it isn't perfect, since my screens doesn't have infinite resolution, but it is good enough. Nothing stops a filter from getting the exact same result as taking a picture of a CRT screen.
- ekianjo 3y agoIt cant replicate what CRTs look like because how the light is emitted from a CRT looks nothing like how the light is emitted from a LCD. No matter how many shaders you use, you cant change any of that.
- bluescrn 3y agoPlaying on an original Asteroids cabinet with vector monitor these days is an interesting experience. I was surprised by the brightness/dynamic range, it seemed way beyond what you get from an LCD. Its like it's got an bloom effect on the brightly-glowing bullets.
- idonotknowwhy 3y agoThey can for static images. They've even got bloom (white scan lines are thicker), simulated convergence and geometry defects, etc. But they can't match the motion clarity of a CRT. My 240hz oled is not as clear as a 120hz or even 60 hz CRT when I put them side by side
- washadjeffmad 3y agoYou're right that this has been a goal since console emulation arose over two decades ago. There's been a lot of bad sprite art spawned over the past 20 years by people who've only ever used LCDs who thought they were recreating something "retro". Only recently has anything really crossed a threshold of reproduction in software that looks and feels like using a CRT on certain types of displays.
- Kiro 3y agoI prefer the "bad sprite art".
- offices 3y agoIt reminds me of how 'we' like statues made to look like Roman statues - after the paint has faded.
- washadjeffmad 3y agoThere's no one right way to enjoy things, just as there's no accounting for taste :)
- Kiro 3y agoI recently watched a documentary on old regal ships and the paint jobs were really vulgar by modern standards, with a lot of random colors all over the place. Obviously the rare and expensive colors were status symbols, and didn't feel tacky and tasteless like it would today.
- anthk 3y agoSo, like comics from the 50-80s with weird palletes.
- bitwize 3y agoApparently when (I believe it was) the Sistine Chapel frescoes were restored in the 80s, there was outrage because the colors looked garish and "like a comic book". But that's how Michelangelo painted them originally; the subtle coloration that people appreciated was actually the result of accumulated dirt, grime, and candle wax over the centuries.
