Actually when I run moonwalker unthottled and go into a game it's more like 650% on my pc and your pc is 36% of my clock speed. If I ran at 1.6GHz, I'd get arounf 230% speed.
So if your AMD apu is less than 45% clock-for-clock compared to the newest generation intel processors than you won't get full speed on this game.
That's almost certainly the issue. Your cpu just isn't fast enough.
