No, the double flash would still be visible. The only way to remove it would be with some kind of extrapolation, like various time warp techniques in VR headsets.
With 60fps@85hz you'd get either severe tearing or judder, so that's a no-no.

Re: Highest perceivable framerate? [good discussion]
Maybe I was using the wrong word. Maybe eye-adaptive motion blur would be better. I didn't condone hold-type blur. What I was referring to was motion blur simulating real life. We perceive motion blur if the angular velocity of the gaze direction differs from the angular velocity of a object (Obviou...

Re: Highest perceivable framerate? [good discussion]
In my agreemend with flood, I feel that eye-tracking motion blur is the only real way to solve motion perception beyond using unpractical refresh rates. And while the eye-tracking needs to be fast, it doesn't need to be sub-ms as perception during saccades is limited and contrast sensitivity drops. ...

So what persistence should I choose (cont.)
I think a good way to do this is to post research here, and discuss and fix it first (i.e. mini-"peer review") Then after a while, with the info collected, post an blog article later. Edit 4. How low can I set persistence and still achieve the screen brightness I need?. First, what screen brightness...

So what persistence should I choose
Very nice. Let me try to add to that, I hope you don't mind. 1. How low of a persistence do I need to maintain image detail? We want to minimize motion blur during eye tracking, as mark explained. To not lose any resolution, we need to reduce blur below 1 pixels. Maximum smooth pursuit for humans is...

Re: Resolution of your eyes [YouTube video]
Heres an interesting video guys :P https://www.youtube.com/watch?v=4I5Q3UXkGd0 While the human visual system - uses (micro-)saccadic movement to increase apparent resolution, this also increases the apparent resolution of video if the framerate isn't too low. So for games/film we only need to care ...

Re: Seeking Math Formulas for phosphor decay & LCD GtG
The curves (strobe compensated) are different for top edge and bottom edge of the screen, due to the asymmetry between the consecutive scanout, versus the all-at-once strobe. The transitions are fresher at bottom edge, than center of the screen. That would be an easy fix, just set the delay to t = ...

Here's a selection of papers. I didn't have time to simulate it yet. P-25: Inter-Grey-Level Response Times of a Liquid Crystal Display (includes overdrive, without the need for LUTs) The inter-grey-level response times of an LCD are studied using two different approaches: a 3-D finite-elements dynam...

Re: Seeking Math Formulas for phosphor decay & LCD GtG
I haven't looked into G2G. I wouldn't rule it out to find something yet.
Edit: in one minute, I found this:

Re: Seeking Math Formulas for phosphor decay & LCD GtG
Wow, that's just the paper I based my earlier calculations on in the first place. (though a slightly higher quality version) I guess I'd just have to read through the whole thing first :) Edit: Thanks , I finally got it (using the updated constants from newer version) http://abload.de/img/pixel-resp...
