Well I'll guess we'll have to see if the original poster verifies it.
All I know is that I've never had a problem in 4 years with Cubase having a latency problem when recording audio.
It only happens when using VST instruments and MIDI.
In fact even if I have every extension and control panel running on my computer and have the latency up to around 200., it still won't have audible latency in the audio. (unless you have the monitoring setup incorrectly..in which case, just do what I said above and it'll fix it.)
