FPS, can you tell the difference?

[david-e-lewis]

I have blue eyes. Under natural light (no influence from fluorescent or incandescent lights) I can see visible flickering at 75 Hz. If reduced to 72 Hz or lower, it causes headaches and eye strain.

At 85 Hz, I cannot see flickering. However, if I focus on a fixed point on the monitor and rotate my head, flickering becomes visible. This commonly occurs when looking at a document or book, then focussing on the monitor. At 100 Hz, I cannot see any flickering, and eye strain is minimal.

I have dark brown eyes. I'm glad someone else said they can tell the difference, I was starting to feel alone hehe

I have dark brown eyes and I can easily tell the difference between 85 and 100 hz

I have red eyes and everything's a blur.

i have green eyes and i can still see flicker when looking directly at an 85hz refresh rate in windows. when there is a moving picture dispayed, like in a game i do not notice the flicker anymore. i much prefer the lcd screen on my laptop to my mitsubishi 740 at home as there is no flicker in desktop applications.

I can just about notice 85hz on my Sony at 1600*1200 but cant whilst running at a lower res. Does anyone know why? It also seems that under certain conditions the lighting in the room ascerbates the problem of refresh rate.

I have one blue eye, and one green eye, I cant tell the difference between 85 and 100Hz if I look straight at a CRT, but if Im looking straight at my LCD screen, then I can see my CRT to the side flicker in my periferal(sp?) vision. Its set to 85Hz by the way.

I have also brown eyes, difference between 85 and 100 is pretty big, but in games it doesn't matter that much

about the FPS , when watchin a movie 25 is enough, because you just watching not interacting

in a game you interact, and if you do a quick 180 turn in a first person shoot the fps becomes important


the more frames you have the smoother it will go, the more accurate it will be , so if the fps in a first person shooter are between the 60 and 120 , it is enough.

More important are the lowest frames in a game, unreal has a good benchmark.

My eyes are green and brown (outer ring is brown inner green)
anything below 75 is uncomfortable for any length of time but i can still see the difference between 75 and 85. this is why my primary monitor is LCD

FPS != refresh rate

A lot of you seem to be mixing up fps and refresh rates. They are two different issues, though refresh rate can have an impact on fps. Anyway, high refresh rate and low fps can be stable and smooth, as long as the changes per frame are fairly small, like if you walk slowly in a game. When there's more action and if you turn the camera quickly a low fps will look really crappy.

Of course, no one needs a sustained 200+ fps, what you need is a guarantee that the fps never drops below a certain point. I'm comfortable as long as the framerate never drops below 30 fps for single player games, and 50-60 fps for things like Counter-Strike. More is always better though

My eyes change color and I can tell the difference between 100 Hz and 101 Hz

I have blue eyes and I can't stand having a monitor set at 60hz. 75 is better and 85hz + is the best for my eyes.

I think when it comes down to FPS..I think I notice the biggest difference if the spikes all over the place like going from 100 fps down to 60 fps.

I have Blue eyes, and can notice the difference between 85 and 100Hz.

Has anyone seen or heard the blurb for 100Hz TV sets?

Its because the color table (especially the Reds) look really crap on a 50Hz screen, and are all blurry and such.
At 100Hz this is supposed to be very much subdued.

Maybe its not just the flickering that people can see, but the difference in image quality?

Also, i suspect that many of the people who can differentiate between 85 and 100Hz are doing so under artificial light.
Artificial light runs @ 50Hz here, and 60Hz in some other countries.
That will set your light bulb or "natural light "bulb flickering, and you don't entirely notice it cos the filament is always hot. The flickering, even slight, should still be there.
As for neon tubes, they just flicker to buggery, and there is no way you can tell a refresh rate with a neon bulb/tube.
One thing to try, go outside at night, and under a street lamp. Preferably one with very little ho's hanging around or you might be bothered.
If you put your hand in front of your face and wave it back and forth, you can see "trailbacks" or uh, standing images? it helps you notice the fact that it flickers really badly...

A power cable running around or near an unsheilded video cable will produce some sort of effect, and electromagnetic interference will cause probs too.
screen flickers when you portable fone is about to ring?
and what if some flicker was generated and u couldn't see it , but it is there...

there are lots of variables to take into account, and i have just waffled and bored some to death, but there it is.
I have an analogue flat panel that can just do 75Hz refresh, but i have no flicker. thats conforting. Its just horrible for watching films, due to the pixel type (not RGB, but one colour).

sorry for waffling, just had to put my life story in too.....

I have silverish bio-electronic implant and I can see the difference between 500 MHz and 500.000001 MHZ

Caine,
A more important reason that films are okay at 25fps is because the images are blurred when the movie is filmed. Real film, with real exposure time, and the recorded image has the blur that your eyes expect.
