Can my computer handle skyward sword?

[Rmfh420]

Hey every one I'm new to using dolphin, I recently got skyward sword and tried playing it and the fps starts out good around 40 fps when the wii more screen comes up. When it goes into the title screen I'm lucky to get 10 fps it's normally at 5 fps and runs slow.
My computer specs are here in this link http://www.engadget.com/products/toshiba/satellite/l505-s5988/specs/
Please help! I'm guessing my computer can't handle it.
