Ok, I take back my last post. I was running the program in debug mode. When ran in release mode, I get approx 400 fps, but when I hover over a taskbar icon, the framerate drops to about 230 fps.
However, I did notice that when I ran the program, the CPU usage jumped from less than 1% up to 100%, so I still think it's from the tooltip stealing cycles from blitz.
