low fps with routine's

[deathsitter]

i know i'm not running the best system for wow . . it's a dual core at least but when i load some combat routines into the bot the fps auto drop's to 4 /5 from 25+ it don't seem to stop the bot from doing it's thing but is there something i can do to fix this

i'm running my lvl 18 druid now using kicks + singular -- if i take a talent spec my fps drops with out one it is fine at around 25fps

any ideas on this my shaman and warrior does it on some profiles and other's it's fine am i missing a setting or ????
