10. THE
RAW
TRUTH
! A_erShot
Pro
takes
full
advantage
of
mulS-­‐threading
! Will
run
up
to
32
cores
@
99%
CPU
uSlizaSon
! OpenCL
port
gave
us
3.5x
performance
gains
overall
! But
there
are
problems
on
the
horizon…

12. THE
PROBLEM?
! Larger
and
larger
images
will
slow
everything
down
! Poor
performance
=
bad
user
experience
! Time
is
money
for
professional
Photographers
! RAW
image
files
had
strict
limits
with
CPU–only
processing
! Users
expect
new
features
that
increasingly
save
Sme
&
money
! Our
users
rank
performance
as
a
top
purchase
influencer
! We
need
to
re-­‐evaluate
how
we
define
UX
