Dark Planet and Hypnotic Dance Spike Processer

Hi Using HALion Sonic as a VST instrument rack in Cubase 6.5
some slots loaded with factory, but when ever I load a Dark Planet and Hypnotic Dance
patch my processor spikes…
imac duo core 2.4, 4 gigs of ram OSX 10.6.8
CI2+ KX49…
Every thing is updated to the latest drivers and updates
including HALion Sonic Content update installed first before HS and HSSE
update patches.
Only Steinberg on the mac no third party plugins
HS, H4, padshop pro, Halion One with synth vst instrument set
and all other vst instruments set. and Sequel 3 for content
Running 32 bit

Same Problem with HALion 4
Any help please
