Um, I'm running the Vista patcher to update all of my old files (which I thought were already updated but apparently are not), but what bugs me is that after all the scanning is complete, suddenly the patcher eats up like 70% of my CPU just to (apparently) download files.

Is there a reason for this? Does it need to hog all my resources for something in particular? I'd personally like to do other things while I wait for the download to complete, but evidently that's not going to happen.
