if you're runing through a debug mode, try adding watch to only a few variables that are of your interest (like fps, cpuutil and so on..) and then change view in lower pane to watch. behold!
p.s. you can always try your pc with debug mode from my game - https://dl.dropboxusercontent.com/u/136 ... index.html
- go to options and turn on debug mode (you can also turn on / off particles to test the difference, it should work way faster without them
