The Legend of Zelda: Twilight Princess frame dropping in certain areas?

[PistOffPol]

Whenever I go into Hyrule Field or almost any area that has a lot of space in it my game starts to drop from 30 FPS to around 10 and 20. Are there any settings I can put on to prevent this?

This is a well-known issue,
Right-click on Twilight Princess, pick Properties, go to the Patches tab, and enable the Hyrule Field Speed Hack.
that should fix it.
