I am not stereotyping anyone. I am giving my experience as to how I can recognize the difference between 30, 60, 100, etc.
You are stereotyping me right now because I play games competitively.
Id is known for licensing out their game engines so this will likely be within the reach of other iPhone developers, at least the ones working for game companies, at some point in the future.
The eye is a complex analog systems. That has different speeds for different types of processing. Most high order processing happens in a very slow range of 4-8Hz.
You get higher speed for motion detection and flicker detection. Typically considered to be around 60Hz in humans.
A good paper on the topic is here. But you need to pay to read it.

Flicker detection is this easiest thing to detect and the fastest thing we can process. After this there is no real visual benefit for higher fps. The point where flicker disappears is called the Flicker Fusion threshold.
It is considered to be on average about 60Hz(Humans), 100 Hz or higher in birds, 300 Hz in flies.

120fps is in use a lot because it is double 60 Hz and 5 times 24 Hz. It first showed up in TVs to let them play back 24 fps movies with the same frame length per frame, while also playing back 60 Hz material evenly.
60Hz (24fps) 3:2 playback: = 50ms/33ms/50ms/33ms ... (this is judder that videophiles complain about)
120Hz (24fps) 5:5 playback: = 42ms/42ms/42ms/42ms .... (even playback length)
This is pretty darn impressive! Being able to "kill anything done on the Xbox or PlayStation 2", and have some potentially great FPS controls with the gyroscope should result in some great new games.
The article says it would "easily run on the 3GS", but is the author speculating or did Carmack actually say this? I watched the video without sound so couldn't tell.
It looked impressive enough that I was wondering if that lighting was actually real-time. Since this is Carmack I would assume that it is, he wouldn't resort to trickery.

What is truly beautiful when you look at a few announcement id made about their engine, is that it's shaping to be very scalable.
Some previous demos were shown on a mac running as a single thread process, and now they say they're harnessing multiple core processors and openCL and using virtual texturing, and the same principles for models.
id software seems to be ready for the next years of gaming with an engine optimized (unlike valve old source engine that was translated to openGL but not much else) and scalable from small phones to multiprocessors workstations.
Really impressive.

I can't picture him doing this without inline assembly. I can't picture Apple letting a developer use inline assembly. This sounds like something he could run on his own phone or a jailbroken system. There would be very big risks if Apple were to let developers do this for software in the App Store.
Movies look smooth with just 24 fps due to the motion blur. Games generally don't have any so they need to go much higher to feel smooth.

That demo is spectacular.
Misunderstanding, stems from the ambiguous meaning of "prone". Rephrase.
You must be susceptible to stereotyping if you play games competitively.
That would be priceless if Apple would reject iD. Resulting in everyone jailbreaking their iPhone to load it via Cydia
Wow! I'm convinced!
Too bad the technology doesn't exist to allow a poster to provide a "pointer" (or "link"), to the information that would back up his vague assertions.
Huh? IMAX movies run at the same rate as normal movies, which is 24fps. The imax film is about 70mm, and it was a big technical challenge to get such a large frame to be fed through the projector fast enough. A 48fps version was never successful.
I find it sad at movies cling to such a low frame rate. It might have played ok in the era of westerns etc but these days with the wide panning shots and scenes it just ruins the film. I mean these huh budget films take hundreds of millions of dollars to produce so it's kind of sad. I understand the reasons from a business perspective. I don't know if digital movies play at a higher rate? (wouldn't matter anyway if the original is still shot on standard 24fps film)
Holy Guacomole - you must be pretty annoyed by fluorescent lamps. Just a quick reminder - depending on the design of your electricity they flicker at 100 Hz or 120 Hz.
Some people can see higher. I can see 60hz out my peripheral vision. . I have to run my monitor at 75hz or higher to not get headaches. But maybe that's different..

Actually he must be a housefly. They have a flicker fusion threshold of 300Hz. In humans it is more like 60Hz.
Yes that is completely normal. This is Flicker fusion threshold which is bang on 60Hz for most people. This is upper rate for human vision rate. By 75Hz most people can no longer detect flicker (or benefit from higher FPS).
