You need set PA.exe to run in "High performance" mode.

Or you just need to google for something like "switchable graphics amd windows 7 how to" and try to find out how to manage it. Or ask some friend who working with computers about this issue.

ok thank you!

Just check for new logs in folder I said you about. You can easily open them in text editor.

First lines of log file contain information about used graphics card, so if you switch graphics card correct you should see something like that:
