Hi,
I compiled the CMT plugins with the g++ options -msse2 and -march=i686
and the freeverb denormals problem (seen with ardour on a dual Xeon
machine) seems to be _almost_ entirely fixed. Also, I don't see any
weird problems with the ardour host (yet :). But, I still see the DSP
load increasing from around 5% to about 15%, although now it is _much_
farther along in the tails of the reverb than before and I get _zero_
xruns. [before, the DSP shot up to 60-90% with tons of xruns and
usually the zombification of ardour].
right, with SSE you still get denormals, they just cost less. I've posted
some code in the past that turns of denormal handling in SSE.
