I don't know if this is a bug or not, but PlayIt Live is running about 70% of my CPU while playing. UNLESS I minimize the window - then it drops to 2%. This is a substantial load for software that doesn't have a whole lot going on the screen. None of the other automation software I've tried has used that much CPU, and they had much more happening in their UI.
For what it's worth, this is definitely running hot and cold. While 70% is the highest I've seen for automation software on my computer, 2% is the absolute lowest I've seen! I'd love to hang onto a low figure, especially since I need to run Breakaway Broadcast concurrently, but I can't keep it minimized all the time; I need to be able to see what's going on.
