How many frames per second can the human eye really see?

PC Gamer: "30 fps? 60 fps? If you've ever debated framerates, the cognitive researchers we spoke to have some complex answers for you."

Tech53402d ago (Edited 3402d ago )

life isn't quantifiable through frames...seriously. it's about your focus on motion. if you can track your hand motion you could see the detail. does this mean your hands are moving from 30 to 60fps? lol......our eyes just tend to lose detail when we do not focus on it.

DevilOgreFish3402d ago (Edited 3402d ago )

If you live in a 30fps world then maybe you were born just too slow. (pun intended)

lol.

mikeslemonade3400d ago

Of course the "hand moving" can be infinite frames but the question is how can we simulate where the naked eye can discern it. In other words where x frames and y frames is actually perceived to be the same because the naked eye can't tell it apart.

fr0sty3400d ago

If it were 30 or 60hz, there would be no need for 90-120hz requirements in VR to keep from getting motion sick.

Kleptic3400d ago (Edited 3400d ago )

These debates always circles around a game's rendered framerate, and if people 'can really see the difference'...when that has never been the key aspect of framerates and video games...

input latency is ALL that matters...and traditional real time rendering ties input latency with frame production. Lowered frame rates have more latency...and it's built in...

a 60fps, 120 fps, 144, 200, etc. may not 'look' different in any quantifiable way...but it most definitely feels, and therefor plays, differently...with the sloppiness of a controller, it doesn't really matter...but with the precision and freedom of adjustment given through a mouse, it's a major aspect of why many chase frames instead of visuals...Ever notice how you hear people talk about 144+ hz gaming and it ends with 'until i tried it'?...you can't show it to someone, you can't 'see' the advantages...but when you actually interact with the game in such an efficient way, it's very hard to go back...

as far as VR...people don't get sick because anything less than 90 fps 'looks' too choppy or something...it's because anything less than 90fps automatically has enough difference between what is happening in front of your eyes versus any movements the renderer is trying to recreate via your own inputs to be extremely noticeable...when those get too out of sync, you get sick...

fr0sty3400d ago

The eye still perceives the difference, therefore it kinda does "look" too choppy as a result, even if your brain doesn't notice it as much consciously. your eye is updating your brain fast enough and your brain is processing that info fast enough to detect it.

morganfell3399d ago

Sooner or later people will realize that framerate is not the main culprit in VR sickness...

FPS_D3TH3399d ago (Edited 3399d ago )

Sloppiness in a controller makes no difference in seeing 30-60-90fps? Lmao ok... maybe you're sloppy with one but you can 100% tell the difference in frame rates and game speed and if you're good with a controller, it's not easy as pointing and clicking no but if you pick up on that frame rate difference you can play much faster and react quicker and it will make all the difference, guaranteed.

Kleptic3399d ago

^yeah...sloppiness in a controller makes no difference in anything framerate wise as far as how it 'looks' to a viewer...because a controller has nothing to do with how it 'looks'...

Agreed @ Morganfell, people aren't differentiating between 'watching' and 'interacting'...People are also making the argument too wide.

30 fps to something higher:
anyone can tell regardless of if its a movie, game, video, etc.

60fps to something higher:
some can tell possibly, most can't...but...

gaming introduces an aspect of this in the form of interaction that plays a bigger part in all of it.

What I meant about controllers was that they don't have the precision incorporated for extreme low latency situations...I'd argue that 60fps gives a better experience in the form of control than 30, but that there is no reason to worry about anything above 60 until using other forms of input. With a mouse, or VR, higher framerates become far more important as the input resolution and precision is vastly superior.

30 fps is fine on any controller with thumbsticks...60fps is better...and acceptable for a mouse, yet 30fps feels extremely weird and delayed in comparison to a controller...60fps is not fine for head/orientation tracking and movement in VR. Higher than 60 brings nothing but improvement for even a mouse, let alone anything VR related. Again, all in the form of reductions to input latency...not because of how the video feed 'looks'.

We aren't quantifying life motion.

We are quantifying digital motion viewed as electrons.

You've lost the plot lol

MoveTheGlow3399d ago

It's worth reading the entire article. The discussion here is discussed by the experts PCGamer is consulting with on this one.

It's interesting. It's like our perception of stuff like 60fps isn't because we stare at a small, narrow image, it has to do with the average of all the stuff we're taking in, front-and-center and peripheral. It's neat.

Rimeskeem3402d ago

i believe a human can detect individual frames when its around 22-23. After that they detect the smoothness of the video.

Goldby3401d ago (Edited 3400d ago )

the Hobbit Trilogy was shot at 24frames per second and alot of people complained it seemed slower because of it. iirc

Edit: my mistake. 48fps

Rimeskeem3401d ago

Much of the 3rd filmed was at 48 frames. Which makes CGI look more fake.

OpenGL3400d ago

it was 48fps, nearly all films are shot at ~24fps which is why they thought the hobbit looked weird

uth113400d ago

Because high frame rate video ends up looking more like a soap opera than fantasy epic.. that takes people out of the immersion

Aloren3400d ago

True. It looks like a bunch of dude wearing costumes in front of a camera instead of a bunch of dwarves on an epic journey.

rainslacker3400d ago

It's kind of what people get used to with frame rates like that.

Anyone that has brought a 4K TV can tell you how it is offputting when they first start watching, because the smooth motion technologies they implement aren't what people are used to.

Eventually you get used to it, and it becomes more normal.

morganfell3399d ago (Edited 3399d ago )

Slightly OT, though much of the first film in the trilogy was shot first, small parts of it as well as some parts of the second and third film were shot simultaneously. During production of the first film it was decided to split the originally planned duology into a trilogy. The process Jackson used is called HFR. And not every theater could show the film in HFR since it requires a $10K projector. Most theaters have now moved to support HFR. The issue with the CGI and HFR is that there is less motion blur. Motion blur occurs in real life. The human eye sees things as they are because it is simply reflecting light but in the processing, motion blur occurs. 48fps removes much of what really occurs. The blur. And the blur occurs in an unfocused state rather than a focused state. Another challenge for game developers.

It was stated above and quite correctly that input lag is the issue rather than raw frame rate.

As regards the film the vast majority of people surveyed actually preferred HFR. I am sure someone reading it will say "Well I didn't like it." Well it may a be a bitter pill to swallow but most people did like it. All in all, they put almost a billion dollars into making those three movies and I put their testing and survey methods over a person's opinion on the internet. And the more people had been brought up on video versus older methods the higher the preference rate. It was many of the reviewers and older industry personnel that were critical and made noise over the issue making it seem more prominent. Again, the press are the culprits here.

James Cameron had announced he was going to use HFR, possible filming at 60fps to shoot the Avatar sequels.

The_Sage3400d ago (Edited 3400d ago )

Rimeskeem is kinda right. The fact is, the vast majority of movies are filmed at 24 frames per second. When you start running frames faster than that it appears strange. Movies begin to look like soap operas. I hate that look. The first thing I did with The Last of Us Remastered was go to the options and change the frame rate from 60 to 30. It completely lost its gritty realism at the faster frame rate. Terrible. I hate the interpolation that TVs do too. It's fine for sports but everything else looks like it's been shot on a cheap video camera with it on.

ONESHOTV23400d ago (Edited 3400d ago )

Get a monitor next time ah i forgot consoles are locked to 60hz.

Omnislashver363400d ago (Edited 3400d ago )

The 60 fps on TLOU Remastered had good motion blur though, after my eyes adjusted it looked great.

60fps on some other games without good motion blur like CoD look terrible at 60 though.

It all depends on how they master the post processing. I'll agree though, movies do look better at 24-30 fps though and interpolation is terrible.

nitus103400d ago

@ONESHOTV2

Rubbish! It depends on the monitor and what you are willing to pay. Monitors and TV's are not rated in "frames per second" they are rated in Hertz which you can loosely relate to the number of fps they can support from the graphics card.

Most cheap monitors are 60 Hz with a 5ms response time and they are usually quite fine for most applications including games. Where you run into issues is when you are trying to view fast motion games such as shooters and/or racing games. Of course, allot depends on the person's eyesight as well.

You can get monitors with faster frame rates and better response times although you will pay more. Likewise, if you want higher resolutions such as 1080p (the most common today), 1440p, 2160p (4K) and 4320p (8k) (yes they are available). You also have to consider screen size and aspect ratio (16:9 is the most common) as well.

Personally, I find that gaming using a monitor is great not just for a PC but for a console as well coupled with the fact that it is a personal viewing device which normally will not interfere with what your family or household members want to watch.

Note: I did not mention "High Dynamic Range" (HDR) since that complicates things further although if you do want a display with HDR you are limited to TV's at the moment although fairly soon you will see monitors with HDR but if you are considering a display device you really should do your homework (I find that Google really does help).

FinalFantasyFanatic3399d ago

I just assumed it was jarring because we're not used to movies being filmed in a higher frame rate, that's why you can always pick out movies with the higher frame rate. It's like playing shooting games with a controller and then using a mouse and keyboard, it feels jarring, but after a while, it feel natural. Although I don't think we have many movies filmed and released in a higher frame rate.

Into the low 100s I believe, as it is part of the eye exam to become a pilot in the Air Force.

loverlink3400d ago

Solid article. It goes very in depth if you guys bother reading.

rainslacker3400d ago (Edited 3400d ago )

Was a good article. Lot of interesting stuff in it.

Best thing said was it's not how much the eye can perceive, but how fast one can react to what they see.

Not looking good. Hopefully Asha Sharma is able to turn Phil’s disaster around.

dveio15d ago

To me it's still quite remarkable how they can cash-in 5.3bn in revenue in a single quarter, since their hardware is basically dead.

Jingsing14d ago

The stock mark is what makes Microsoft remarkable, They have convinced every institutional and retail investor to just keep piling money into them. Like many big tech giants they are just a big growing pyramid scheme. As long as people keep dropping money into ETF's that cover the market Microsoft will always be liquid. At the same time it is completely stifling innovation and competition. People need to start being more discreet in how they invest their money as it's killing the system.

Tanktopmaster9214d ago

Once they re-evaluate exclusive all will be fine….

S2Killinit14d ago

Riiiiight because people will just flock back to them for one or two games per year.

Jingsing14d ago

15+ years of bad performance is what they call irreparable in business. It is time for them to sell off the assets and get out of entertainment.

Tanktopmaster9214d ago

These declines are on the back of extra revenue received from releasing games like Forza horizon 5 on PlayStation. So I’m being sarcastic here when I said they should go back to exclusives. Killing off a revenue stream from Ps5 sales will only make things worse
