Ah shit the nerds are here

@@professorhojo7205 😂

Not exactly an expert, but wouldn't having higher resolution monitors and running a game at a higher resolution make AA obsolete. Since there is a lot more pixels to fill in the gaps where traditional 1080p monitors couldn't. For them it might not be an issue but for us peasants we will see the difference through our shitty monitor/laptop.

@Mehdi Alfiguigui Hah yeah with the film grain and the like with compression logarithms. I was watching a steamer play black mesa where radiation snow/static effect caused the whole picture to degrade to mud until he left the area. I thought youtube was downgrading my resolution due to bandwidth, but no. It's kind of amazing how much pixel change information a simple effect can generate. I can barely notice film grain effect on games. I wonder if cheaper TV's (Vizio 70' 60hz) can't portray it well, or just me.

@@professorhojo7205 What's not nerdy about this channel?

And yet I still don’t know which one to use! I get choice paralysis when there’s too many lol.

@@Quizack This video is obsolete in some cases, but still relevant :) I'd be amazing if there was an update to it. Nowadays you usually have 2 options - TAA (Temporal Anti Aliasing ) and some sort of upscaler like DLSS/ XeSS/ FSR/ TSR (and sometimes you have Dynamic Resolution Scaling for additional boost in performance). DLSS 2.5 and above is qualitatively catching up with native+TAA and sometimes surpasses it. XeSS is catching up with DLSS and FSR 3 is soon to be tested, but on paper looks to be on another level when compared to the not-so-good FSR 2. If you can afford it and don't mind lower frame-rate, go with the TAA. If you want a higher frame-rate and max out your monitor, go with an upscaler, choice of which depends on your GPU. If the game you're playing has options for FXAA, MSAA, TSAA and SSAA only, go with the SSAA. Avoid FXAA if possible.

@@Quizackall depends in the performance profile and options available

Best example for the need of anti aliasing

bruh...

thank you for chuckle hotobu. Sorely needed -alex

Lower resolution then add a Reshade sharpening filter.

Potato graphics

Yeah what's with all the negativity

@@Krystalmyth 😂

Yeah I came to this video thinking it would mostly cover stuff I already know but that stuff about mip maps and specular AA was very informative. Great work Alex.

Temporal antialiasing is especially interesting, they've just scratched the surface here, which is understandable. All kinds of crazy cases need to be handled in dead-simple and efficient ways, for it to be usable. Basic principle is - your recycle data from the previous frame. But what when things are moving? You use the same vectors used for motion-blur to figure out where that spot was in the previous frame. But what if that object just came into the frame and was't there in the previous one? What if something just instantly disappears? It then reveals pixels that also don't have any previous data. What if an object is transparent? Do you use its motion or the motion of the background? Do you make it a special case? You get the point, fun stuff :)

Daniel Pierce I only knew about outer edge aliasing and the texture aliasing from a far

TheBurek Temporal antialiasing is my least favorite personally.. too blurry

But it eliminates more aliasing than any other method, when implemented properly, so it's always my AA of choice, if available. There's usually a "sharpness" setting alongside it, to counter-act the softening, try adjusting it.

nothing to confuse here its simple . fxaa and taa are blurry trash. msaa is good but takes tons of fps, smaa is best but is too light

​@@sarunas8638Well, TAA is a lot blurrier than FXAA, literally ruins your image, FXAA is just useless unless you're playing on a high resolution and want a cheap solution.

Whats the size of your 1440p monitor?

BuzzaB77 soooo much clear. Thank you, man

i got more infomation after spending 2 mins to read this comment than watching a 14mins video

Indeed this was actually much clearer than the grid thing

Or you could low-pass the audio.

This dosent help. How to fix aliasing in a line?

Google it.

deferred seems pretty self explanatory, it's a time thing. sub-pixels were visually represented in the video so should also make sense.

Heard of these terms on random, do not hold ANY technical expertise, programming expertise or anything else. I am throwing shit out of my head without reading on it so it is that much possibly south of the proper meaning: Sub pixel: pixel within a pixel. While your monitor is not able to show a unit less than one pixel. game engines and GPU's can process units less than one pixel. Speedrunners also use the term as some Speedrunning tricks in old Sega and Nintendo games are based on manipulating the game character into right sub-pixel position (so, right position within unit less than one pixel) to trigger a glitch with benefits. The word is pretty straightforward too by itself: "Lower than pixel" or "pixel inside pixel" - that is just the word itself. Defer is not even a technical term, just fancy word for something that could just as easily be used in real life situations. Just means "delayed" As for what I got from it, I had mixed SSAA and MSAA a one and the same and thought the saying "it is basically rendering your game in double/quadruple resolution" meant for MSAA, not SSAA as SSAA was more or less non existent unless hacked by hand into the game by someone with GPU powerful enough for it, so that would mean; not me. Also, as someone who happily snaps on ANY anti alising setting on without really thinking how it affects the game's look - more or less always happy with the results, learning the downfalls of the modern AA solutions is nice. I mean if I was mean I would be saying this is more about not understanding English than technical terms but that would be mean.

He didn't water the video down with explanations outside of the scope of the video, which is arguably a good thing. I get it, it's annoying when an explanation for something requires explaining itself, but it's also annoying for people that don't need those things explained to sit through those explanations to get to the part they came for. If something confused you, figure out what that thing means, then come back.

"keep doing you" I cannot wait for this phrase and others like it die out.

I think it's because he was using a high resolution to begin with, if you play an older game like Counterstrike with a lower resolution AA makes a bigger difference

@@fabianscharf2454 I believe it would've been nicer with a zoom in to illustrate his point. He's talking about pixels so probably better to zoom in when he goes through all that trouble in showing us comparisons. He only zooms in like once for the ghosting

Its BC KZfaq compresses it if you had the game in front of you you could probably see or atleast "feel" a difference

You can totally see it when playing games, but the amount depends on your setup... 4 Example If I connect my PC to my 4K TV and play at 4K at around 1.5meters from my 4K 43inch TV I barely see aliasing, on the monitor 1080P 22 inch I play at like 30cm and can totally see a lot of annoying aliasing. However I mostly never use Anti-aliasing since no matter which one I chose it blurs my game too much and I hate loosing sharpness, on my AMD GPU even FXAA that barely does a thing already blurs too much 4 me, on my old Nvidia actually anti-aliasing worked better than on this AMD GPU it had way better anti-aliasing quality. Multisampling is the one that looked kinda nice but never had hardware to ever use it since its first appearance. I specially hate TAA it blurs like a crap and has a lot of motion artifacts.

Bro you will need a compound microscope to know the difference...

Alex is hot.

True, he seems to know his stuff and is adding a lot to the DF team.

Its the slight german accent.

No he's not he's boring and slow and can't pronounce words right he should be fired

Gaige Mecromancer wrong

Agreed, couple it with a 25% sharpen and it's as good as it gets.

same. Temporal AA is Bae

ye I used to hate it before I discovered lumasharpen. now it's bloody brilliant

After playing games on switch I absolutely despise it, makes fortnite look like a compressed youtube video and there's no way to turn it off

TAA + FXAA Is cream. (and you lose around 5% perfomance which is cool)

Exactly Andy :D a defense of per object blur sounds like a video in the making! -Alex

So does that mean I should keep motion blur on? I've got a 1050ti if that helps

Mishak Heyman yes motion blur makes motion feel much more natural to your eyes

if the game already ran at 60fps or above, i dont think you really need motion blur.

It's not so much about need, it's that motion blur makes any frame rate feel more natural. Even at 60ps there's a ton of motion happening between frames that motion still doesn't look entirely natural. Your eyes expect to se that information, so motion blur delivers what your eyes are expecting. In fact, with motion blur, there's very little reason for higher than 60fps, because above 60fps your eyes are already blending frames together, creating their own sort of motion blur (although you'd need about 600fps or more before it would become as smooth as motion blur). There's still some slight improvement whenever your eyes can track with fast moving objects, but even if you have 144fps, motion blur will still make the motion appear more natural than without.

I really can't see the difference in most games and it gives me an extra 10-20fps which honestly makes the game more enjoyable than just blurring all the frames incorrectly.

You need a girlfriend

You need an RTX 2080 TI

you need better AA

@@DenisLiasis Maybe that's how she talks to him.

@@raziel3099 she tells him he need a girlfriend? Ffs.., I wouldn't be comfortable having a gf like that.

Honestly I do the same at 1440p either 4x MSAA or no anti-aliasing at all

MSAA is the only one I genuinely like even if it's more demanding. Though...less games are using it now :(

well that and SSAA for older/indie games. I just fired up Dead Space after seeing it in this video. Running at 5K, I didn't see a drop below 200fps, even going up to 10K I was still hovering in the mid 60s. Running Dead Space 3 at 5K, I was getting 150-170fps. I am using a 1080ti for this, but it shows, that weaker card are capable of using SSAA for these types of games.

Thats how I'm thinking at 4k, no aa seems a better option in most games.

Oh god, when I started Far Cry 5 it had TAA on as the default, i nearly vomited, I turned motion blur off right?

The video was horrible. He even failed to explain aliasing properly. Aliasing is the result of sampling at an inadequate rate. Given a white line next to a black line with an instantaneous transition between them, you'd need infinite bandwidth, that is infinite samples, infinitely high resolution, to reproduce the input perfectly. So by the time the graphics card has produced (has sampled) a white pixel next to a black pixel, the damage is already done. Aliasing then is the fact that different input data will lead to the same output samples - aliases of one another. The solution is trivially easy: low-pass filter the input. That is, attenuate the part of the signal above your sampling bandwidth.

it's 4 am where i live rn, and i'm watching this

He's also playing the original 2006 Prey for much of the video.

Fuck yeah! I wonder what Kasma Corp is all about.

There’s gonna be dlc?!?!?

What about the whole KasmaCorp ARG? They were teasing something There's definitely new content coming.

Go look at Arkane and Prey twitters, they've been teasing Moon DLC or standalone DLC for months. BE3 will likely be the reveal.

I like seeing the jaggies while playing my OG Xbox with my component cables because they actually help me adjust the sharpness on my TV so they look nice and sharp

Dragon Warrior 1 says hi

Same. AA makes games look like a blurred mess of shapes. No AA makes objects stand out more.

@@fu_ck1 I personally only use AA when a game is running at a much higher resolution so blurring is minimal

Having crispy non-jaggies is even nicer.

Anti aliasing is a complex subject. There's already a ton of videos out there that explain some of its functionalities in layman's terms, but this is a rather in depth look on what it does, which I think fits digital foundry perfectly. An in depth look on a rather complex subject will always be harder to grasp than small light videos on that same subject. Its like a camera, everyone can grab a camera and take a picture but not everyone knows what makes a good picture, thats what in depth courses/videos/papers are for.

@Mehdi Alfiguigui he means techquickie linus channel, 5minutes explanations which is actually great in everything

get an mCable, mClassic or seiki u-vision cable that'll help by applying Anti aliasing

@@WednesdayMan dude this comment was over a year ago. I have an RX 580 now

@@JEST3R_ my suggestion will still help since it does anti aliasing externally so it can help boost fpa

Personally, I always turned motion blur off whenever the games allowed me to do it. I just feel that motion blur (and maybe vignette)just something that not need to be simulated

Motion blur is a must for me on 30 FPS games or when using TAA.

Motion blur is only bad when you're in a multiplayer PVP game

Hi! Hrm. So for this video, as a response to feedback on my last one... I really tried to slow down my cadence of speech at times, and also attempted to make sure that all the phrases I use (the big ones) are explained in sentence form and keyed on screen with aa visual and text overlay. Do you know per chance what would have helped in this video to not give you that feeling? What I could have done differently at a specific point so you would not be overwhelmed by the words being used? I am grateful for feedback. Best, Alex

Dictator93 For what it's worth, I think you did a great job breaking down a fairly complicated subject into an easy to understand video. Your use of visual cues were extremely helpful and I don't think you could have done it much better without belittling the intelligence of your audience. With that said, your initial definition of aliasing seemed too abstract to me and made it a little hard to follow. In the future, it might be beneficial to break up more complex terms/topics and let each part form the full picture at the end. You explained it very aptly through your examples but I can see people completely unfamiliar with the subject getting overwhelmed by that definition you led with. My main criticism of your most recent videos is that you seem like you are trying to sound like you are speaking naturally, which ironically makes it sound unnatural. Not sure you can really do anything about it other than keep practicing and get better with time. You're already improving noticeably with each video. I'm loving the content you are bringing to this channel and look forward to your next video!

Have you watched Matthewmatosis' videos? He presents his videos with a dry voice, but a lot of people still enjoy listening to him, I know I do. Check out his Ocarina, Ico, or Mario 64. Also, check out MrBtongue. I personally didn't have problem with your video since I think it's short enough to rewatch or pause and look up if I was still confused. I did feel like it could've been longer and I would've preferred more examples from a little more variety of games. Sure that you already know, but people dislike change or anything new, so people are going to be extra critical. But, there's also people who enjoy something new and different so keep it up, and I look forward to your next video.

Dictator93 For me the problem lies in the pace of your talking; it is too fast. Take it slow, have some time in between sentences. This is extremely important so viewers can process the information you just gave. I notice you jump from sentence to sentence without giving me enough time to think about what you said. If you take that into consideration, the video would be better. So, it is not your voice or the language you use, but it is the speed at which it is all presented. But besides this, don't forget you did a very good job on making this video.

Just watched your video and i enjoyed it. Explanation vise, a short definition of sub-pixel would help. Aside for that, there were moments that confused me (or my eyes/brain) as your rapid switching of AA in Doom didn't actually show me what you talked about. On the other hand the Witcher 3 example was perfect (or the robot hand ghosting in Doom / Tomb Raider blur / or Crisis example). I guess i would say you should maybe focus more on visualizing the issue (like you did in most examples) for maximum effect instead of using a slightly advanced vocabulary to illustrate (or define) the issue. Being precise is important and am not saying you should ignore it, just put it there when you are sure people actually understand or at least can identify what you are talking about. Also please consider making a playlist of tech / methods / algorithms used so you have more time to properly "review" them. In this video you glanced over few different topics, introduced several ideas that work on different philosophies, at different times with several factors that are unique to each of them. Each of them is quite interesting and just glancing over them (as there are a lot of them) can confuse people. P.S. Don't get me wrong, vid was great, TL-DR (overview of them) has a lasting value, so the critique is just nitpicking on little stuff.

r6 siege before the 2018 update still supports Msaa, now they have only taa, fxaa, dlss, and taa combined with ssaa slider

The issue though is that it takes more GPU resources to jump up from 1080p to 4k than it does to add most AA solutions to 1080p. In principal, as more and more people have 4k capable hardware, Anti aliasing could become less of an issue - certainly as far as 'edges' are concerned. The stair stepping will still be there but much smaller.

Yes, these issues are what I wanted to see him get into. The performance trade-off, older games not being made to be rendered at 4K properly, interface shrinking, weird textures at high base resolution, etc. Even in the comments below you can see people saying that increasing base-resolution is the silver-bullet and I wanted to hear him layout its benefits and drawbacks versus types of AA.

Increasing the base resolution is in a way similar to SSAA though - you render more pixels.

Similar yes, but not identical. There are notable differences.

Subi_fan no 4K at 27 inches is 163ppi, the pixels are still pretty noticeable, you would need a 21” screen at 4K for AA to be pointless. At 21” that’s 210ppi

With the old prey game in the background lol

Yeah I felt the same. For a foreign person (I'm assuming) his english is perfectly spoken.

Really? I'm German and to me it's like "Ugh, that German accent!" - it's not horrible by any means but it's there. 😁 Anyhow: Alex' vocabulary seems to be pretty good!

Yes, i'm being serious. I hear many english speaking germans. For example, many think Sebastian Vettel is one of the best speakers but he misses out many words, a little broken in parts and pronounces certain words funny but not this guy in the video. 100% right. Oh and there's nothing wrong with a german/austrian accent, no one sounds as tough. Alpha male like, apart from Russians, Ukranians.

He is actually American according to DF's John Linneman in a comment below.

NovaPrima, why did you edit your original comment to such extent? It was perfectly fine. Thinking american accents don't sound good is normal to say. People always attack other accents, they could use some criticism too. I myself am british and our accent at times can sound extremely boring. I think he must be an american-born german or maybe born in Germany but lived the majority of his life in the states, so his accent's not so glaringly pronounced.

Add AC Oddysey to the poor implementation of TAA. It's actually heavier to run it without any AA at all than with AA. And the result is a blurred mess that screws up a spectacular environment.

why would you even bother using anti-aliasing for online/competitive games anyways?

@@m0rph3u5. Because I like my game looking natural instead of stabbing me in the eye each frame?

I think Ghost Recon Wildlands was the worst implementation of TAA I have seen so far. Even at 5K as soon as you move the whole picture turns into a blurry mess (and yes motion blur turned off). The best implementation was Doom's TSSAA. What really bothers me about TAA are games that have it unremoveble caked into the game.

Taa is the worst for me. It doesnt work on anything else than 4k. Also the worst example of taa is BFV and Fallout 4 even the division. Its simply the worst version of AA and works only on 4k, yet 4k still isnt a standard. Best cheapest proper aa is either MSAA Or the really the cheapest SMAA combined with luma sharpen. But even still. Blurring image isnt a true AA. Id rather suggest to not to use Temporal / Fast AA ever.

I forgot that it looked that good. When I consider some other games from 2006, it really has held up well.

@Dr. Loomis Your mom was OK.

Honestly 2017 is not that bad

bethesda brutally murdered human head's prey 2, never forget! prey 2 was by all accounts a great game coming, showed playable scenes and trailers and everyone in human head studios said, that the game's quality never was an issue. bethesda financially bullied human head studios with holding back payments to hopefully result in human head studios selling themselves to bethesda as they were quite impresed with human head studios work and wanted to own them. the result of this was, that human head studios was forced to stop the work on prey 2 and barely survived financially and prey 2 was never to come to us, even though it was relatively close to completion. so again, don't give bethesda one CENT! ever again. take your money and throw it at self published games or indie games either self published or published with a not monstrous publisher (they exist). use your money to support beautiful art like prey 1 one was and prey 2 surely would have been and not to suport the greed and psychopathy of publishers/studios like bethesda. also prey 2's game story was later told and it would have been great, who knows maybe at some point human head studios with people's support can buy the rights to all the half finished prey 2 and finish it and release it themselves or under a different publisher and different name, because of course bethesda also reused the name.... for a completely different game, hell they even went so far as to tell indie studios to change similar names like "prey for the gods" needed to change their name to "praey for the gods" to avoid a possible lawsuit, that even though bethesda would be a wrong and a piece of shit yet again in that case a small indie studio can't afford a lawsuit and can't risk the game that they are making. so again fuck bethesda, destroyer of art and projects of love.

More like a villagers " Huuuh" sound from minecraft

I got like a Foppish Gent vibe.

I think its just that engines implementation of T-AA. Games like Fortnite and Battlefield have excellent T-AA while Siege and Far Cry 5 have some pretty poor T-AA. Also T-AA is best suited for resolutions above 1080p.

It does soften the image, but when resolutions are are really high I think its the best looking AA solution. Even R6: Siege looks great when you upscale on PC and Uncharted 4 looks awesome as well.

MSAA can't do shit against the type of aliasing we have today. Also, TAA isn't blur filter. But I'll give you credit for liking Prey 2017. It's great.

haven't played Prey 2017 yet but Prey 2006 is bae

i think r6s is just a bad implement of T-AA. T-AA in bf1 look amazing. I now play r6s with anti aliasing off, since T-AA in this game just too damn blurry, even with 2x/4x res and 100 sharpening

Dead Space in 4K is still beautiful

Why did they use it as an example? I thought it looked fine even on my 360.

BIG-NABZ couple years ago I tried replaying it on my pc at 1080p and the jaggies were awful, even with AA. So I put it in 4k and the game was transformed. I guess you were just not close to the screen enough to see the edges.

Still the best game I ever played.

You're not my dad. You can't tell me what to do.

Also, it made me sad to see Dead Space. Screw you EA for dismantling Visceral.

The new Prey is awesome, but it really doesn't have much to do with the old Prey. I wish they would have named it something different.

Is that game Prey 2006?

There was a PREY 2 planned. Got canceled i guess. The E3 trailer looked so good for PREY 2

Yes.. this is prey 2006!!

Pilotgeek freak.

Biased Milk Hotel funny, Doom's temporal antialiasing is one of the few I like. I guess that's why they make these things optional!

Man I've hated jaggies since the moment we went from tube crt tvs to 720p lcd.

I remember playing PGR3 at 720p the first time and thinking wow why does this look so messy.

Hi Vdel! I would love to have covered it, definitely, especially since Crysis 3 showcased in the video uses it natively... and so well. But as always... there is a production time to consider. So I make concessions and try and focus on the biggest points always if I can. But yeah, definitely! Love me some good MSAA extensions! Best, Alex

Surprise reply from the man himself! Well, I guessed that it might've been too much to cover in addition to the more known techs. Kind of ironic though if you think about the fact, that the purest way of AA, supersampling, has more relevance than multisampling nowadays. Hooray for DSR/VSR.

Not a middle ground, it's to be used with MSAA to combat aliasing in alpha textures that MSAA doesn't detect since its not within geometry.

Also, you have no perceptible German accent. I wouldn't have even guessed your German heritage if it wasn't for your farewell. Wish I could speak a foreign language so well, damn.

THank you for typing this out Pixel Shade! Means a lot to me to read!

4k will be gone soon and 12k will take over. 40k will be after that and then we'll move to a new era beyond pixels.

Well, he talked about SGSSAA, didn't he?

csaa = nvidia version of msaa with more coverage samples eqaa = amd version of msaa with more coverage samples mlaa = a type of post processing aa similar to fxaa trssaa = ssaa but applied only to transparent textures sgssaa = ssaa but with a different sample layout

CSAA (Nvidia) and EQAA (AMD) are variants of MSAA that attempt to make the sampling cheaper to perform (or improve quality at the same performance cost, depending on how you look at it). They do this by taking extra "coverage samples" on top of the usual MSAA samples. I don't know exactly how they work behind the scenes, but the gist is that these extra samples are very cheap but they also won't necessarily improve the image in some cases. Best case scenario, the result will look like as if you did the full-quality MSAA with more samples, worst case it'll look like MSAA without the extra coverage samples. Now the naming scheme for these modes can be confusing. Nvidia just gives you the total number of samples, so for example 16x CSAA means 4x MSAA samples + 12 coverage samples. AMD on the other hand just tells you the number of MSAA samples, but the total number is double that. So 4x EQAA = 4x MSAA + 4 coverage samples, 8x EQAA = 8xMSAA + 8 coverage samples, etc. MLAA is a simple postprocess AA algorithm similar to FXAA or SMAA, but it seems to have fallen out of favor lately. The concept behind them all is the same: you render the aliased image, then you try to figure out where the edges are and somehow smooth them out afterwards.The details of how exactly they find the edges and blend them differ between these algorithms, so each produces a slightly different looking result. TRSSAA - transparency supersampling. MSAA only takes care of polygon edges, but it won't do anything about transparent textures, the transparency effect can still produce nasty jagged edges (think fence/metal mesh textures and foliage for example). So you can supersample just the transparent areas to improve that. SGSSAA - sparse grid supersampling. Supersampling but with a better sampling pattern that isn't grid-aligned, like explained in the video. Note that standard MSAA modes on all modern cards use these improved sampling patterns by default. This is why downsampling doesn't necessarily do as good of a job at removing jaggies as proper MSAA/SGSSAA would. Rendering the image at double resolution is basically the same as 4x ordered-grid SSAA. This is why you should only use downsampling as a last resort when none of the better MSAA/SSAA modes work with the game and you've still got enough performance to spare.

He already talked about Sparse Grid Super Sample Anti-Aliasing.

What about DTDHGETHFSTFHAA?

You don't even really need resolution scaling at 1440p+ 1440p is pretty affordable these days. You can get a Lenovo IPS 1440p monitor for $270 shipped. That's $100 cheaper than the cheapest gtx 1060 3gb on amazon.

i get that too with the post AA.. It's like I'm trying hard to focus on something but I never can. It's tiring and yes, makes me feel like im hurting my eyes.

I completely disagree here. The thing with anti-aliasing and motion blur is that they're commonly thought of "blurring" the picture, but they do the exact opposite. They introduce more data to the frame, either by rendering at a higher resolution for anti-aliasing, or at a higher framerate for motion blur. It is entirely possible that one player with motion blur or AA would notice an object going past him very fast (or far away), while a player without those won't. Now for solutions like FXAA or motion blur based on the camera speed etc, I can definitely understand turning these off (I would do the same). In the end it's just a preference, whatever works for you is fine. Of course in the best of both worlds we would render at 4k with AA and 200 FPS with motion blur (in which case the motion blurring is barely noticeable), but that's not really an option yet.

TL;DR Version: I agree with what your saying about SOME of the AA techniques (what I call the GOOD ones lol), but there are some techniques that do NOT add information- they literally destroy information in a mathematical or signal-processing sense. They are used to make the scene look "better" but not actually closer to what the 3d information actually says. And worst of all, the destructive ones are more common all the time and sometimes are the ONLY option. Huge Wall Of Text Version: I see what you're saying about AA, and I think I see what you're saying about motion blur: that, for example, it would turn an fast moving object that moves past you in one frame and disappears into a streak that you could see over two or three frames, and that you would get more information about the object's motion and shape than just having it appear in one frame and vanish. Likewise, sampling some or all of a raster frame at higher than the actual resolution puts more information into the pixels that otherwise is thrown out by aliasing. The problem is that some techniques for doing that use the 3d geometry data to add additional information to each frame, but some techniques just look at the final frames and basically do photoshop filters on the output frames. Some motion blur techniques literally just keep pixels from the previous frame and blend them in the next frame (which decreases information) but some techniques actually use the game world information to blur the object across the pixels and between frames: MSAA does what you say, real OG motion blur like a few XBOX 1 games and some PC games had does what you say. "Screenspace" or post-processing AA or motion blur that only works by looking at the pixels afterwards is destructive, even if it removes annoying artifacts like aliasing jaggies. Any technique that does "extra" sampling of the game world beyond the normal rasterization is definitely better than the same resolution without it, agreed. Really the most effective and simplest and most scaleable way to go: Just render big and downscale it with a simple downscaling algorithm, and skip the fancy tricks. It's almost as good as the best of the other techniques and it uses up the leftover performance of your PC if all your settings are already maxed out and your framerate is already at the max your monitor will display. Sometimes it makes sense just to throw gpu memory, bandwidth, power, and electricity at the problem! :O rant: this turned into a huge blog post and i dont have a blog :O seriously my disappointment in this video and the really smart comments down here are making me want to try making a video ... or maybe more like a illustrated comic or blog post :P this channel is usually pretty decent, but some of these comments are way more accurate and more in depth, and aren't trying to sound more intellectual than they are...

Conner Harkness You are the reason developers stop adding non post-processed anti-aliasing into their games. It makes me sad.

Actually Anti Aliasing can be something you absolutely need to get an advantage... With "proper" anti aliasing (like MSAA) things that is invisible at distance like a thin rope or wing of an aircraft becomes visible at MUCH larger distances. Without anti aliasing thin things like that is invisible or best case blink in and out "existence" until you are getting a lot closer. This is specially important in Combat Flight simulators like IL2 and similar were seeing your opponent and what he is doing early give a huge advantage.

jakedizzle taa + sharpern image good combine

All AA "blurs" the image, but not actually like a gaussian blur would. It's what happens when you average pixels. You could also look at it the other way, no anti aliasing leaves and unrealistically sharp image that you would never encounter otherwise.

That was exactly my thought
