Dolphin 3.5 Wind Waker Low FPS

[Shonumi]

If for some reason Dolphin can't access your default text editor (happened a lot on Linux) simply right click the game and go to Properties. You should see the Gecko ID in the form of something like "GZLE01" for NTSC-U region games and "GZLP01" for PAL region games. In your Dolphin folder, go to User\GameConfig and edit the GZLE01.ini or GZLP01.ini file in your text editor. Change the lines that Garteal mentioned.
