Sounds like the answer to this question requires much research,
would wall clock time appear faster if you ran double framed
at 120Hz?

And what's the effect of motion blur on this effect, presumably
the cell animators wouldn't draw this so perhaps the whole issue
relates back to the incredible observer excitement induced by
temporal aliasing?

I thought I posted this but I didn't get it back so it may just
have gone to one individual. Like I indicated the last time I sent
this, it's during discussions of subjective effects that I like to
remind myself of this description.
