I'm using the 002 rack with a new pc (2.8 ghz, 1.5 gigs ram). I've been having all kinds of CPU usage issues that are still yet to be resolved. I'm maxing out at only 10 or so tracks and a few plug-ins. I can play back only a few passes at this point before getting an error message, unless I disable half the tracks. I have a dedicated serial ATA harddrive for my sessions, so using the system harddrive isn't the issue. I close every other program. I turned off hyperthreading. I know people running more tracks with a lesser computer, so are there any other possible major or minor changes I can make?
