hi ed,

i can't really help you with your graphics problems ... i think, you
should try some fedora forums ....

well, i've been experimenting with icc lately ... this does give a
better performance, but it's not 100% gcc compatible. to figure out the
performance problem, the way to go would be to use a profiler (like
oprofile). i'd also recommend to use devel, since the vectorized
versions of the basic dsp functions are between 2 and 5 times faster
than the compiler-generated, but it depends on your patch, how much you
will gain.

oh well, and if the rendering is done by the software instead of the
hardware, this will also make a difference ...

hth ... tim
