[@CaptDnaDonut]

I would like to see part 3

[@SwaggyKillzz]

I want a better point of view at those graphic things :D

[@kaidon39]

Me two! He made two of these already, why not finish it while he's at it? :D

[@lucasmoore2470]

As do I good sir!

[@Rawkabilly57]

***** half life 3 confirmed! And yes I want a part 3 of the video!

[@JCstealth2344]

***** ha

[@Alpha1200]

I've never liked depth of field in games. It actually makes things feel less realistic because my eyes already have a depth of field when looking at a game, I already focus on some parts more than others and other parts are paid less attention. To have the screen do that for me feels wierd to me.

[@billnklp]

+OneOnOne1162 im pretty sure your eyes cant produce depth of field on 2D images such as a screen. All parts of the screen are at the same distance from your eyes so focusing anywhere on the screen means your eyes are focused on the whole monitor.

[@Alpha1200]

bill nklp Actually depth perception is produced in more than 1 way. There's two ways of binocular depth perception: The distance from both images from the eyes compared (and their difference) and the amount your eyes have to turn inwards to see an object clearly. Then there's also several ways of monocular depth perception which includes but is not limited to seeing things with higher spatial resolution (more stuff in the same area) as farther away, automatically compensating for linear perspectives (meaning that things at the end of two lines that slowly converge are seen as farther away), there's also movement parallax (which means that objects that move more slowly through your field of vision are seen as farther away and those that move faster through it as closer by) and several other things. The non-clarity of things is not produced by any of these things but is produced by information fallling on something called the "fovea" which is a small focal point in your eyes which has a dense concentration of cones (the stuff we use to see clearly and in colour), which still in fact works when looking at something specific on a monitor (and even when reading), so you see that's bullshit. There's still depth perception when looking at a game. PS: You said this to the wrong guy, because I'm a psychology student and I'm currently studying for an exam with a chapter about perception (including depth perception).

[@abduljakulkalakisal-salini9409]

+OneOnOne1162 let's just say it was made as a compensation or an illusion to cover up for the pc's limitation in rendering... if everything will be rendered in 3d for as far as you can see, it would be more likely that there will be a huge performance drop. take elder scrolls oblivion for example... when you look into the horizon, the landscape is just a blurry low-res 2d wall but as you go closer to it, it's slowly rendered into 3d as you walk/run towards it. and that ps3-quality game is highly playable on pentium 4 3GHz

[@Alpha1200]

Abdul Jakul Kalaki Sal-Salini That's not the reason that was given here though. But yeah, that is a thing. A thing VR may be using in the near future, I've heard. Eye-tracking and all.

[@eddson11]

+OneOnOne1162 I was just about to write this exact comment. Some games do DoF horribly aswell, like FPS games putting the gun in focus when you aim down sight, Why would you focus your eyes on the gun if you're aiming at something further away? And some games have way to much DoF on distant objects instead of having it on things that are not in the centre of the screen, and it's jsut as bad when they have it the other way around and make everything except what your crosshair is on, blurry. I've seen some games that does DoF really well but it is rare.

[@JustinWayneTM]

Depth of Field is one of those settings I always turn off. It looks pretty great in screen shots but I always find it gets in the way when actually playing. As I'm not always looking at what is centered, or what my character happens to be focusing on at the time.

[@hellseagle21]

My god Depth of field gives me headaches, you're constantly moving and constantly looking around, especially in a pc game, Depth of field like you said looks good in a picture, but not much else...

[@OffTheSpot22]

Depends on the developer Some devs do gorgeous depth of field work, others end up making the game look worse

[@hellseagle21]

SpookyKid94 Well yeah, but there's very few games that do it right....

[@afifkiryu94]

araragi senpai.....

[@chavovaldez]

Yes DOF is terrible. You spend all this money on a rig, then update it so you can run it with HD textures. Then you upgrade it more so it can run DOF on top of that which really just blurs those textures out. That is hypocritical. Also your eyes don't really act like that, you aren't always keeping your eyes in one place. Your eyes are spending as much time looking at the background as what is in front of your face. When you look at far objects the distant objects should crisp up and closer objects blur. DOF is a bad hack. Maybe in the future games will be able to track our eyes and tell where we are looking. This guy has it on in force in all of his videos though.

[@ShadowDragoon004]

Not a huge fan of GameStop overall, but I like this guy.

[@mangosarefun]

GameStop btw LUL

[@alfredharrison597]

fail...

[@SilverEye91]

Make a third one please. You give very good and easy to understand descriptions of these settings and I would love to learn more.

[@asongoflimeandfibre5487]

It has been reported that some victims of torture, during the act, would retreat into a fantasy world from which they could not WAKE UP. In this catatonic state, the victim lived in a world just like their normal one, except they weren’t being tortured. The only way that they realized they needed to WAKE UP was a note they found in their fantasy world. It would tell them about their condition, and tell them to WAKE UP. Even then, it would often take months until they were ready to discard their fantasy world and PLEASE WAKE UP.

[@bradleymaskill11]

Wut?

[@DaltonRoberts.]

That was deep.

[@ChokolatThundah]

A Song of Lime and Fibre youre an idiot.

[@John-Spartan]

Thank you very much Cam for explaining Ambient Occlusion. Sometimes is hard to find a simple explaination for a specific term. These are the best Reality Check episodes so far and I can't wait for part 3.

[@rahulgospel12]

Please do a part 3 as well...they way you deliver the whole information is simple, crisp, and to the point with video examples. In short, amazing ! I'll be eagerly waiting for part 3.

[@Chrispy4949]

A Part 3 would be brilliant, thank you. These videos have been great for teaching my nephew who is new to PC gaming, and these videos explain it all better than I can.

[@ThisMissJackson]

Part 3 PLEASE! This is such a helpful series.

[@amoblack9845]

Make a part 3 man, i like these reality check vids on this topic.

[@SuperKittenator]

This is something I have looked everywhere (a lazy person would look) for a simple explanation of pc graphical and this is what I was looking for. Please continue...

[@mickeygt42]

Part 3 please, it was amazingly useful. Keep up the great work!

[@DevSivram]

Part 3 please Cam. These videos are so informative.

[@RajGheevarghese]

Please please a part 3. These 2 videos were great, and very informative for a newcomer to the gaming scene such as myself. Thanks a lot!

[@TheBioDrew]

I would very much like a 3rd part of game GFX explained, I could look all of them up but your voice is kind of soothing.

[@Cross64786]

Good explaining about PC GFX. Waiting for part 3 :)

[@HKeeperfim]

Lack of anisotrophic filtering does not cause farther textures to blur, it cause textures at an angle to the camera to blur.

[@trick29420]

Correct! Mip-mapping is the technique used to reduce texture resolution (sometime blur) at a distance.

[@GloriousKev]

I love this series!! Please do more.

[@BenRender]

do part 3 please, this series is fun!

[@JesusSlanda]

I love these videos! Please make a part 3.

[@godwinmadho]

these are awesome, part 3 please!!

[@hanifhalimi]

part 3 please! thanks for posting these kind of videos

[@dennismcbriar3678]

Yes do a part 3 please!! this info is awesome ^^

[@LamininD]

Part 3, yes please! Super helpful videos!

[@merbusa]

Part 3 please! Really enjoyed.

[@Natdog99]

Best video yet thanks gamespot

[@rafatvaz]

I am really enjoying these videos!

[@MihajloKarlicic]

Another part would be awesome, Cam.

[@topsykrett4439]

i really ove your intro/outro animation + music, its fantastic combines so well great video, thx 4 explaing

[@idoperach]

Part 3 please! These videos are great

[@Gruggo]

A part 3 would be great, those extra things you mentioned would be great to hear you talk more about.

[@FlyBird]

Part 3 please!

[@chorras2]

Great explanation again, thanks!

[@CentsTwo]

Very easy to understand, these episodes. Part 3 would be great. It would also be nice to have a PC specs explained. Since you explain things so accessibly.

[@soldierrob909]

I already knew everything but it's still fun to watch

[@phylwx]

Gimme episode 3 NAO.

[@GrimReefer1983]

He already gave it to you 1,5 years ago...

[@phylwx]

Now THATS good service.

[@ArjunAjith]

+phylwx LOL. Smooth As F***

[@mrstratau6513]

Thanks for posing, Great info.

[@wazzarlich]

part 3! very well done =D

[@TheKleanupCrew]

Yes, please give us a part 3!

[@mbik5272]

Pls a part 3. Its really helpful

[@stasgsgsgs]

Cam, you've got one more vote for the part 3 of this series. Keep up the good work, mate. ;)

[@OffTheSpot22]

Totally support these videos Not enough people are educated on this stuff, makes gaming on PC way better when you know exactly what settings do and can figure out if your rig runs well with it or not.

[@robdoggaming5161]

I would love to see a part 3. Very interesting stuff 😊😊😊

[@Shacko117]

Part 3 please! If as many more you have to do to cover them all, thanks Cam

[@zeropercent_]

Omg Reality Check is great, one of my favorite youtube shows.

[@RJ_____________]

good explanataion. keep the good work

[@SKazclaw]

Do a part 3, very informative!

[@katalyst666]

Part 3 please, Have actually learnt a lil on here :)

[@whosane3450]

PART 3!!! this was good.

[@sawyermckay8108]

These are really helpful. Hopefully I'll have the dough to build a PC one day, and then I can refer back to these.

[@bledsoe1995]

Part 3!!! So much education...

[@FreightTrain54]

I'd like a episode 3, this is great info!

[@NordicGameplays]

You need to make part 3 so you can cover motion blur, that's so important for a good graphical experience.

[@VinnieSaint]

Its usefull when you have low fps , it makes the game kinda look better , or at least thats what i heard...

[@NordicGameplays]

VinnieSaint What it does is mixing frames together like they do in movies. Most games doesn't use motion blur, that's why you get a crisp screenshot from games, but not from movies.

[@VinnieSaint]

NordicGameplays yeah , as i said it is usefull for games if you have low fps, if you dont , turn it thr f*** off

[@NordicGameplays]

VinnieSaint What? It is used on tv for low frame rates, but it looks a lot better with high frame rate too.

[@VinnieSaint]

NordicGameplays I prefer to not use it at all , but if you have low framerate it makes it look decent , but when you have high framerate , you really just turn it off , its annoying as all hell

[@Mavryk]

I'd like a part 3! Its handy to have all the information in one spot.

[@naruhearts1]

POV (for games) is how you are you are seeing the characters actions. Its like when people say First Person or Third Person View/game. First person (when you are looking through the eyes of the played character) - Bioshock,CoD, Portal Third (zoomed out, usually behind the character) - Zelda,Uncharted, Gears of War Then there are the ones that can do both like Fallout, Elder Scrolls (some like skyrim), Star Wars Battlefront 2.

[@JackLe1127]

anisotropic filter is not about blurring the texture. it's about re-sampling the smaller textures in different direction as opposed to mipmapping (or isotropic filtering) where the textures are shrunken in both x and y dimensions. The size of a pixel in the x and the y dimension on a texture are not the same when you look at it at an oblique angle. Therefore, you need to prepare them in one dimension at a time.

[@SevObzen]

Part 3 please. Planning on getting into pc gaming soon and stuff like this is quite helpful.

[@kie1845]

i bit of advice (even though it's six months late) IF you are building one go for a quad core 3.0 ghz cpu prefferebly with hyper threading 8 gigs of ram a dedicated graphics card (like a gtx 960 or something) and i hear SSDs are nice so get one of those to , with those specs you can prob run like 90% of game out today :D

[@keiyuan]

Yes, part 3 please

[@SConundrum]

more, more, this was very useful

[@KennyKennTV]

Thanks for the info, can you do a part 3 and a summary of what options to prioritize for best performance to prettiness? Thanks!

[@Retro.foxhound]

I like this guy his videos are great but I don't know why there are so many haters disliking these videos !!! There's nothing to hate.

[@Lemonsharky]

FOOOOOOOOOOOOOOOOOOOOOOOOOOOOOX!!!!!!!!!!!!!

[@enicot]

It's the troll patrol, they live inside the youtubes and dislike everything they see. They can't be bothered to simply close the window or move on to another video, oh no, they actively want every video on youtube to have dislikes, so they endeavor to do just that.

[@TheSilent199]

Filthy paesants, that's why.

[@hishamjalal9078]

its the console peasants. they dont understand this video. thats why. pathetic lowlife peasants.

[@abdullahmahmoud827]

cam is the coolest dude in gamespot... he should get more private shows like this one

[@CFkid3]

These have helped me a lot considering i do my gaming on a laptop, i would love a 3!

[@discokossan]

>my face when video won't play >my face when i learn it's not avalible on mobile >my face when it's actually not avalible at all >my face when

[@kujoforever]

Bang us bangus

[@Kiwidoom]

Part. 3 would be fantastic!

[@DarkMageofNyx]

a part three would be amazing

[@hazrdusroman]

I would like to see part 3 of course :)

[@sebianoti]

Yes yes yes make part 3

[@kgonepostl]

I've been playing PC games for close to 30 years, and I still don't know what some of these meant. Thank you for clarifying, you're doing the lord's work!!

[@demonpower101]

yes PART 3 PLEASE

[@C0nv3rsE]

of corse we want a part3, this is very informativ and very usefull for a pc gamer

[@torpshire6362]

[@TheAlreadybeentaken]

Never change your profile pic.

[@jackewbo1283]

[@ahmedhawz7283]

bro its been 5 years and you still haven't changed your profile picture

[@Ularg7070]

Even with the KZbin compression I saw the line of blurrying inching back as you walked around the scene in Bioshock Infinite. I've heard people say that 8x is the max for AF that you'd want, 16x adding in artifacting, tho I've never seen images showing this off. And yeah, you should definitely do a third episode. I recommend looking at Arma 3/2 for post processing stuff because they go insane with it. And I still don't know how to run that game well.

[@BEARWALKEN87]

We want mooooreee nice vids!

[@DanterNero]

I like both part 1 and 2 and absolutely wanna see part 3 ..

[@TheLonalriis]

Yes to part three, please.

[@DragonRider24100]

Yes please part 3

[@sxbha8713]

It actually helps me

[@Malum3538]

Definitely a part 3

[@mouthazar1]

i would love to see part three please do it.

[@trinadhp7352]

thanks bro

[@gipson123]

Part 3! And more!

[@archangel2015]

I would love a part 3.

[@MordAjantor]

yeah! we need more of these! And then combine them all in one video. ...POV never heard of that

[@peterg7718]

Yeah part three plz!!!

[@TheRewyn]

Would love a part 3

[@MrSomeGamerdude]

I also like to add to the FOV, when you do increase FOV (let say 110) it will give a a tunnel or fish eye look when moving around, which is great if you have two or more monitor. (maybe you should do part 3 and add amd eye infinity & nivida 3d surround in the mix, hint* hint*), but throws your balance off when trying to find distant target near the corner on a single monitor.

[@framtonnuttel8082]

Yep...please do a part 3.

[@Shade9239]

Yes to Part 3

[@MartinTrybus]

I see that peasants are disliking the video. Nonetheless, make the next part. Very interesting so far;)

[@itojusedi]

I'd Really like a part 3 :)

[@novusstream]

Great show... love this nerdy stuff even if I'm a console peasant, it still applies. ;)

[@cloned81]

I want a part three!!

[@thisscreensucks]

Make as many parts as you can find a reason for. PC gaming master race loves our in depth look at how gaming visuals work

[@grzegorzmaj3675]

Yes, part 3 pliz :)

[@XxAPartofMexX]

The Console peasants/fanboys must really hat these videos...

[@XxAPartofMexX]

***** *hat I live a life of no regrets.

[@cris7198]

Fanboys? Yes Videogame enthusiasts that would like to learn more? Nope

[@JohnKaz]

I actually quite enjoy these videos (I'm mainly an xbox player but getting more into pc gaming now) Then again I'm quite a geek when it comes to the technical side of games.

[@kimothel2443]

Hat? I have a hat, it's lovely.

[@billlllllltard]

ViciousAlienKlown There is not too much reason for console players to actually learn it all, I can understand that it's fun to learn about it all but since they have no actual control it would make sense that they have less reason to actually care.

[@connord6194]

YES PART 3! Post processing and GPU max buffered frames please!

[@mjnelson91]

I would love to hear your take on "Post Processing." From my understanding Post usually lumps together AA, AF, AO, Motion Blur, DOF etc, and all those other post process effects into one obtuse option. How close am I to understanding that right?

[@anuragd948]

Another video would be great !
