@ Prominent: I seemed to notice the same, though I'm not very sensitive to the issue so was not sure about it.
We could try making it flash every length2 non-0.016 sequence (just change sequence length >=3 in line 7 to >=2),
I had tried but that seemed too much flashy to me, and maybe the flash could be a bit misleading for the eye too..
Also, while tinkering, I noticed a strange thing:
setting a different framerate in the application properties (say, 40)
and then forcing a framerate of 60 at start of frame (so it should be the same as the basic test mfa)
gives very different and unexpected results, with extremely long non-0.016 sequences.
And the ball seems to be more jerky to my eyes.
Not a clue what this could mean though...
Was thinking we could record every relevant data possible (like in those test mfas and more)
and then have some good eyed (and good willed ) clickers press "spacebar" when detecting a stutter,
then look back if there was any noticeable pattern of some kind in data recorded, near the spacebar pressed.
Same here for salamanderpants video: I can see stutter very well there,
and recognize having seen the same other times while tinkering with Fusion,
though running that mfa isn't "almost" stuttery at all here,
not sure if because of my machine, my monitor, or my eyes
it's a very evasive issue
I wonder how much would be difficult testing Phi's intuition, I guess only devs could tell.
