Not what you’re looking for, but I remember watching a documentary (decades ago) where they wired people up to EEG machines and then showed them images for increasingly slight instants. After a certain point, like 1/1000th of a second or something, the individual would stop reporting seeing anything, but their brain would still register it. And furthermore it would register it quicker than in the cases where the person was still able to consciously notice it.

you literally only need monitors for a double blind test, that’s it.

youre talking to a printer

they just moved the goal post. now its “the human eye cant see past 1000 hz”

​

we’ll see about that!

I have to wonder if they have ever even tried higher refresh rates/FPS? The difference is so apparent.

Reminds me of people claiming that 30FPS was better than 60 because “the human eye can only see 30FPS”. At least the “30FPS is cinematic” argument made a little sense, despite the fact that it is completely wrong in the context of games.

Human visual processing breaks down at different rates. I had an extremely informative college course which I took fairly poor notes but here are the basics.

Object recognition - 24hz. Actually got a live demo for this one. Flashing 24 unrelated images per second and students could call out when a duck was visible. About half of us could spot it even when most other images were unrecognizable. This rate targets the visual cortex.

Flicker Fusion threshold - 60hz, the rate the eye can percieve that a light is flickering vs solidly lit. Depends also on the display technology. This rate targets the rods/cones of the retina themselves.

Motion Recognition - 500-1000hz, Inside the retina itself, the human eye has special ganglion cells which detect edge patterns traveling between rods/cones, these are clever hair trigger comparators that can spot differences in detection smaller than the original signal (stilll ~60hz but unsynchronized) but this information travels separately from the object recognition signals to the brain and is never fully re-incorporated. Motion blur/interpolation used in film almost complete blinds these cells and the absence of these signals is relatively subtle. Unblurred 60hz film and video games can still trigger the stop motion effect. These cells need much higher rates to be completely fooled.

Think of it another way, if you have a vertical line moving across the screen, you want atleast one frame for each motion cell. If the line jumps pixels you get more like motion stripes than a motion image. If you jump multiple pixels per frame, skipped motion cells report zero motion and the perception of motion breaks down. To complete the illusion you nearly need a new frame for every column of pixels(not every rod/cone cell is connected to a motion cell) . This is why perception still subtly changes up to absurdly high frame rates.

Please purchase a dictionary and acquaint yourself with the “O” section.

You are wrong. And the same thing was said about 120 vs 240, and surprisingly 60 vs 120.

This is an age old argument. But those who use 120 vs 240 will tell you it is not just noticeable, but will affect your hand eye coordination timing.

Placebo should not be ruled out, but I believe you have the bias, here.

I like that everyone else is assuming they meant Counter Strike 2 and you’re talking about Cities Skylines 2

There’s community servers now, so maybe you could find one that has that. Don’t think it’s in official yet though.
