not tons, but it is much safer, then -O3, IMHO.

my cpu utilization doesn't get that high, only aobut 60% on a pIII 450.
i found xine pegged my cpu using captain_css patch, but apperntly its very
badly tuned for FreeBSD.  I do get some jerkyness using x11 output, but
using --yuv yuv --overlay helps some, but i do notice the jerkyness is
worse for very active scenes (though that just might be my eye being able
to notice the difference), and twards the end of the movie, which sugests
that throughput from the dvd drive to the cpu is the issue, though i can
get much faster throughput ripping audio cds.  that probably though is an
unfair compairison.

i haven't had any sound problems, using the dsp sound module.  though if i
resize the video window, making it significantly smaller, sound gets
faster.  resizing it to around the correct size sets it back to normal.
starting it at a smaller size doesn't have this problem though.

i haven't had any problems withs the the gnome interface.  or any of the
others for that matter, but i havn't played with them really.

i'm very very impressed with it.  i'd like to congradulate the developers
for all thier good work.
