Can my laptop run super mario sunshine well?

[Shonumi]

Your laptop is very weak for Dolphin. I have a similarly configured laptop (well, my sister does to be more specific) and it doesn't run that game very well. Keep in mind that PC games are not emulators. They're two completely different programs, and how one uses your hardware's resources is going to differ from another. Modern PC games tend to emphasize the GPU whereas emulators generally emphasize the CPU. Your CPU is too weak to run the game at fullspeed, and you may find getting "acceptable" speeds to be likewise difficult.
