E-Prime Stability

[David McFarlane]

With regard to XP vs. Vista/Win7... For the 
longest time I advised EP users to stick with XP 
32-bit.  PST now certifies EP2.0.10 to work under 
Vista/Win7, and with both 32- and 64-bit 
platforms, and I have subsequently reversed my 
advice.  I have been testing and doing some 
development using a dual-boot XP-32/Win7-64 
machine, and EP2.0.10 has worked well for me on 
the Win7-64 side, maybe even better than on the 
XP-32 side.  E.g., I have been testing sound 
latencies -- under XP-32, I get sound latencies 
on the order of 30 ms.  Using the *same* machine 
booted to Win7-64, and using the available 
CoreAudio API, I can get sound latencies solidly down to around 10 ms.

But don't get me started on movies!  Movies have 
been a headache in every release of EP2, but for 
that matter we have also had trouble with movies 
in PsychoPy.  So I do not think this is the fault 
of EP, I think this is just the nature of our 
digital movies, a lot of this attributable to the poor state of our codecs.
