Good enough to run Wii games?

[booty900]

I just got this emulator and I am seeing what games can be run. I got New Super Mario Bros Wii and started to play. People on this site say it runs perfectly at 60 FPS. I can only get it up to 45 FPS. It seems to slow to play. Is there a specific build I should be using or is my laptop not good enough. Heres the specs.
