ot: need computer nerd help - dsp question

[james fowler <twostroke@gmail.com>]

scenario:

bidule running on win xp, 4 gb ram, fast processor, etc. 

the dsp monitor inside of bidule reads 30-50% at any given time (depending on number of instruments currently at work) but in task manager cpu usage hovers around 10-11%.  is there a way to boost dsp allocation or whatever (dunno if that's even a real thing) so that bidule has a little more headroom?  i find that under certain circumstances the dsp meter peaks at over 100% and results in all kinds of crap glitching and/or freezing.  given my computer's specs, it would appear to not be a hardware problem but i don't know for certain.

any and all help is greatly appreciated.
