LostWinds is a silly game, where the game logic is tied to the rendering FPS. For this reason, playing the game at anything above 60fps would make playing on PC faster than Wii. Similarly, playing on a more powerful PC would make your runs way faster, especially given LostWinds is an RTA category.

Below is a link to a guide explaining how to limit your FPS. Personally, I use the Rivatuner Statistics Server :)
