Realizing I don't really have a current powerhouse of a computer, the old Z3ta ran fine and was a low load.  Liking the new 2.1, but on my Intel P4 2.8 with 2 gigs of RAM is making my CPU meter hit the ceiling with some patches and hard to automate stuff without glitching video.  Was the Z3ta upgrade that much more a heavy hitter?
 
And yes... new computer...probably coming this summer, but I hate the thought of installing all my stuff all over again.

there is a choice for the user to pick 2X oversampling, i think. uncheck that, if you haven't already, and you should see better results

thanks,  yes I see options for that and moved to a lower value which helped immensely.  appreciate the reply (and fix!)
