Eyes don't see in FPS, but the motion effect can be archived with 24 frames per second, the human eye can detect a change in one fps of 500 in a second if 499 are black and one is white, but if the image is bright to bright with much less FPS you can see a fluid movement, it's all matter of brightness and contrast.
If your monitor works at 60 Hz it can only display 60 FPS, most TFT's work at 60 Hz, however i've seen CRT's topping 100 Hz.
The eye can see WAY more than 30 fps, i remember some research showing that in some circumstances the eye could see the difference up to 13 thosand FPS, but tbh once you go past 60 the difference becomes less noticable.
TV's run at 24 FPS (PAL) and 29.97 FPS (NTSC), but they are inter-laced which i think means that each frame is blurred to make it look better
What the hell, have everything I`v read been wrong then?
Can we see 13k FPS, or see the diference on up to 13k pictures each second?
I don`t belive that :/ I`M pretty sure that it`s under 100FPS when it comes to what the human eye can notice, or see, or what you would call it.
Interlaced means, that the images even and odd lines of the image are updated in a alternating manner. So the whole image is updated 24 or 29.97 times per second, but half of the image is updated twice as fast. So basically it doubles the framerate for the same bandwidth, but it does make the image worse.
A great image from Wikipedia:
On the subject: Human eye can process more FPS than 30. With more FPS the difference becomes less noticeable and you don't notice individual frames, but rather the smoothness on the image. And RiGun pointed out human eye can spot a different frame from a big FPS image too, if the difference is big enough that is.
You really shouldn't think about the eye in computer terms since it's quite different.
no since your monitor can still display higher framerates through stitching 2 frames together (barely noticeable on a good monitor) additionally any kind of vsync requires buffers delaying the image you see to whats happening in game
Indeed. Vsync drops frames that are sent before the monitor refresh signal is sent. I never play with Vsync on, tearing is the (small) sacrifice I pay for the fastest image possible.
Vsync shouldn't affect your framerates but as a keen CS:S player I noticed (to me) severe laggyness with vsync on - others have too.
Thats crap, on any Game, you can see the difference Between 30 and 60 fps... you can see smoothness (especially on FPS games) up to 125 fps, then no more, you can only feel it after that
Regardless of whether I'm playing LFS or a first person shooter, the game gets noticeably choppy for me if it gets below 60 fps. For ultimate smoothness, I need it around 85-100 fps.
I'm the kind of guy the CPU and video card companies love.
it also has to do with your screensize. on a 15" screen objects "travel" less way between two points than on a 42". Thats why some HDTV standards use 50 instead of 25 FPS.
As said, games need a much higher framerate to look realistic, because of the lack of blur. Other synthetic animation like cartoons try to fake the blur. At http://www.albinoblacksheep.com/flash/snapanimation you can see a tutorial how you can do it in Flash.
You only see FPS above your monitor refresh as tearing in the image as it is then composed or more than one frame. You need vsync on to stop this, but in reality I would leave VSync off unless your FPS is double the refresh rate or you will lower your FPS.
With the current trend for LCD monitors anything above 60fps is pointless because they cant display it.
That said you can notice far higher fps and people with 120Hz CRTs and FPS to match will get silk like movement.
What you HAVE to avoid is big changes in FPS. So if your systems stable FPS is 40 yet can put out far higher you are better locking at 40-50 so you dont see huge changes in FPS. A drop from 60 down to 40 at point will show up and feel like a stutter due to the bigger distance you cover.
The other thing to take into account is the faster the car you are driving the faster the required FPS or the motion will feel less smooth, you will see the jumps in frame.
