REFRESH - Framerate and the quest for graphical fidelity
Вставка
- Опубліковано 15 лип 2024
- Framerate in video games is everything. For hardcore gamers, ensuring zero dips in frametrate is top priority, with anything less than 60 frames per second deemed inexcusable. It's the single most important factor in delivering smooth, responsive gameplay, and it is the defining metric in which high performance hardware is measured on. Poor graphics? With good gameplay, a forgivable sacrifice. Low resoution? A retro style. But a low framerate? Unacceptable. It doesn't matter how good the story, graphics, or music is. A low framerate is sure to interrupt even the most casual gamer's experience. Ensuring smooth, responsive gameplay has been a primary aim for video game developers since the birth of consumer video games in the 1970s. But the idea of frames per second being the standard metric for measuring responsiveness is far newer. In fact it wasn't that long ago that refresh rate and gameplay differed from region to region.
Gaming has many forms: PC. Console. Portable. Arcade. Each with their own unique characteristics. For high end gaming, the PC rules supreme, but consoles deliver a similar experience for a much large audience. For action away from home, portable and mobile gaming provides a solid platform. And nothing can beat the experience of entering a neon-filled arcade with a pocket full of change, and time to kill.
All of these platforms have influenced how we view refresh rate in video games, and the metric of frames-per-second is now a ubiquitous concept. But where did this even come from? When did framerate become a mainstream idea? How did each decades' graphical styles affect it? How did innovations in graphics hardware improve it? And finally, just how important is having high frames per second? But before all of this... just what is framerate?

Always found it sad when I find a Channel that has great videos but such a low sub count
Haha tell me about it :(
@@TechKnowledgeVideo I found it just a few hours ago, and I'm glad to be a new subscriber. In time, your audience will find you. If you ask your viewers in your future videos to like, comment, share, and subscribe, it will help with your channel's growth. I know it's kinda corny, but these are the things that the algorithm looks for when judging what content to recommend to viewers (even dislikes are beneficial to your channel, because it counts as user interaction and interest). I'm shocked at how often content creators don't do that, but wonder why their channel does not grow. You're an excellent content creator, please take my suggestion with the positivity and helpful spirit in which I have intended it to have.
Thanks David, I’ll be sure to include this in the next video :)
nah the channel sucks.. has these long awkward pauses between each sentence that comes out of this kids mouth. This alone makes these videos very slow and boring and makes script reading way too obvious too.. yh no one enjoys watching this. It's funny how this kid made at least 10 videos and no one told him this.
This channel is going to freaking *explode.* I just found it and watched the history of CRAY and was astounded to discover how little subscribers they have. Anyway, congratulations on your first million in advance. You deserve it.
Hahahaha well it may take a bit of time but thanks! :D
I think you're missing two important concepts. The raster hardware used to literally chase the beam, meaning average input lag could be made as low as half a frame if the developer was careful. 3D hardware required at least double buffering; at best you would have 1.5 frames of average input lag. Multicore and deeper pipelining of graphics increased the average frame delay by several frames; it's now not uncommon for the average input lag to be 3-5 frames. 165 FPS today can feel less responsive than 60 Hz on a CRT.
The other concept is persistence blur. Your eyes don't move in discrete steps, but the image does. So if the image is constantly backlit your eyes will move during the time a given frame is illuminated, smearing out the image by an equivalent amount. Following an object move across a 1440p screen in a single second (moderately fast) means that it moves 43 pixels per frame at 60 FPS; that's equivalent to a linear blur of 43 pixels. It's a muddy mess. Now look at a 60 Hz CRT; it is illuminated briefly and then remains on your retina as your eyes move. Giving a crisp, blur-free image. ULMB/BFI/Strobing does not compete successfully against CRTs; the duty cycle is too high. A CRT feels as crisp in motion as a 1000 Hz LCD; it's simply no comparison.
Very good points!
@@TechKnowledgeVideo can you make a video about next gen for cpu and gpu
Hi Master nobody, I'm currently creating the next video about supercomputers (I post updates on the community tab) but in the future if people want to see this then I could make a video about next generation CPU and GPU designs
@@TechKnowledgeVideo glad to see you still making videos. It's finally moving around the algorithm, discovered it through the algorithm only a few hours ago. Hopefully your much deserved exposure will arrive sooner than later
I am late to the party but would definitely want to see these topics done your way.
👍🏽🇬🇧 October 2023
This video is a *masterpiece* - as is everything else I've so far watched on this channel!
I just discovered your channel, I absolutely love your videos! Please come back and make more!!
Thank you! I’m currently working on a video right now, if you check the community tab I post updates semi regularly which have some screenshots :)
I like your style.
Soylentgreenb made the points I would have put here, leaving me free to just add a little to the discussion:
When someone says, "duty cycle too high", in this context generally involving a CRT for comparison, the overall intent is to convey:
A CRT actually illuminates only a small portion of the display area. The SloMoGuys did a video on this with a high speed camera and a CRT displaying NES graphics. One can see it literally doing the image production a pixel at a time! CRT displays are really fast! Like bring your best high speed camera and hope it has the beans type fast!
That, coupled with a very high contrast ratio means almost literally painting the pixels onto our eyeballs. Persistence of vision takes care of the rest.
Sidebar: I have noticed our animals will watch TV now in this age of newer display technologies. I believe their vision operates faster than ours does and to them a CRT was a flickery mess. An LCD or plasma display is something they can see as a moving picture like we see it, but I digress...
Just want to say I enjoy your style and believe you are doing a fine job bringing topics many feel are important to people who will likely benefit from your efforts. Nice work.
I found your "digression" absolutely interesting. So you think your domestic animal has a understanding of the abstract and actually very philosophical concept that touches several topics of serious scientific research you call "a flickery mess"? Wow, that gave me a good laugh:) Think about deeper ... or place a mirror in front of them and watch em fight or get in love, hehehe. Unless you do not own a dolphin, a great ape or a raven bird as pet (which I do not hope, it is animal cruelty), those animals are not even self-aware. Without self-awareness there is no "entertainment", which includes that you cannot point out that some uncommon bad framerate is not to your liking. Also your experience is totally anecdotal and that means you cannot make a conclusion like that. In fact I myself know about budgies regularly watching TV in the 1980ies. But they did not do that because they like watching TV. The only reason was because we were "friends" (or better: I was part of their community, their pack, their social structure ... however you wanna call it) and we shared quality time, hehehe. TV or listening music or playing piano does not make any difference in that matter. Oh and why wouldn't a being that registers and observes his environment NOT watch "moving pictures"? That's what we do as humans ... and we are animals, too.
But you are right with the visual apparatus. Not only does the visual apparatus work faster in fleeing animals, for example, but also the visual cortex in their brain. That's why I always ask "gaming enthusiasts" if they have the brain of a housefly:) You have to know that only the public speakers of the marketing department of the GPU manufacturers have and need such lightning fast reactions ... to convince the ordinary young man (ALL OF THEM!) from the street that he absolutely needs the newest 240Hz Technology. Or he simply cannot compete against all the other house flies ... LOL
It is like with your impression of the animals. It looks like the way it is, but that is only because you made the wrong conclusions. There are many many guys out there who swear adamantly that their new 120Hz equipment is now butter smooth versus their 60Hz older stuff. Completely ignoring any other upgrades (including software refresh cycle changes) they made and more funny: This comparison is only a feeling ... not even a side by side comparison, which makes their claim a ridiculous one:) Meaning: Absolutely laughable because not measured and scientific ... which no STUDY in biology and physics about the topic does not support.
The thing about houseflies is that they could make useful use of the framerate upgrade, but just not humans. Competitive e-sports back or forth ... humans just have a range of reaction time and how this can be improved by training. Above 120Hz it really gets into the nonsense "audio-gold-cables" category:)
But to the rescue of houseflies: What don't do is for example: They don't have to admit that they were tricked by the GPU seller. This is completely out of their character. Humans cannot accept this and have to invent absurd pro-arguments for their new GPU and monitors (which is okay to buy and upgrade ... but just not because of the display-rate reason).
Anyways, who cares? It is not our money (I hope you are more "conservative" in those things, too). I wish you a good day, gaming experience and that you have a good time with your animals:)))
@@dieSpinnt Modern displays present an entire image, not a raster like the CRT does.
Their visual system appears faster than ours does, and that likely results in the average 60hz / 50hz CRT display being that flickering mess I noted earlier. And an LCD or similar display would appear quite different to them.
I did not speak to most of what you wrote and prefer to note their behavior is different now that they are exposed to non CRT display tech.
Again, all that you wrote about their understanding is beyond any point I wanted or needed to make. Your words, not mine.
The remainder of your comment is not something I chose to speak to. You made many assumptions and then responded to them as if I somehow were actually a participant. i was not, and with that need only say I will not respond to you again.
Yes! New content 🤩
"The 8-bit computer market was gaining ground, as kids convinced their parents that these machines could be used for education as well as games. Yeah, right..."
Haha! Yup. That was me in the early 90's;
"But look, it comes with Encarta! (...and Battledrome.)"
Great video! Well produced. Inspired by Ahoy at all? Looking forward to new videos. 👍🏻
Thank you!
Love the content it reminds me of a much bigger channel called Ahoy
Thank you! :)
Commenting for the algorithm.
Good work!
Hahaha thank you! :)
Great video!
Thanks!
Come back man, we need you now more than ever.
Well good news! I’m working on a new long-form video at the moment that’ll be out later this year :)
Once at 30 FBS I can't tell the difference in a game when its higher.
A miss mention. VR, in it the frame rate is fundamental, so you don’t get sick
How odd that you didn't mention either ATI or AMD. Anti-Aliasing and Anisotropic Filtering also deserved a mention. They were god-send for gorgeous 3D gaming, in an era of horrible jaggedness.
In the PC CRT days you could find plenty of monitors capable of 75Hz and sometimes higher depending on resolution.
It was pretty hard to find the monitor not capable for at least 75 Hz, as anything less would produce a visible flashing. 85 Hz were pretty common.
@@ValdikSS2 Yup, although the school ones always seemed to be clocked lower, I always saw them flickering
3.3k views? wha...? I hadnt looked before watching, and my guess was one of these almost 1 mill, or 1.4 mill vids - kind of a semi-important thesis that most interested parties would have seen. But 3.3k?!?! ummm... huh?
Low refresh rate CRTs were physically painful to use. If you're talking about a computer monitor then 60Hz was a miserable, flickering, headache inducing experience.
Your videos are really good. The only thing Ahoy has on you is that stupidly sexy and deep voice of his.
Hahaha, thank you :)
I don't know who that is, but hopefully he doesn't do these 2 second pauses between sentences just lmao🤣
Dude you literally have 2 to 3 second pauses between sentences.. that's way way too long
