Wind Waker Very Slow Good Computer

[link_alves]

Hello, my name is Abraham and this is my first post. A greeting to all. I don't understend because The Legend of Zelda Wind Waker is very slow in my computer. The speed emulation is 60 or 70% and the game speed is very slow. 20/22FPS

The game is a PAL Version.

I change a lot of settings and see very guides but the game is very slow. This is my hardware and software:

Intel® Core™2 Quad CPU Q6600 @ 2.40GHz
AMD ATI XFX 6870 1Gb GDDR5
4Gb Ram DDR3
Dolphin 4.0 (Before I test the 3.5)
Ubuntu 13.04

My settings in the emulator are this:
All settings by default (The speed is the same in all resolutions)
OpenGL
EFB copy to Ram ( I read this in the wiki of dolphin)
Audio LLE ( I read this in the wiki of dolphin)

Please, I need your help. I've tried everything but the game speed is unplayable. I can try all your suggestions

Sorry for my English, its very bad, and thanks for a lot.

Your cpu is too slow for efb copy to ram and LLE audio. You will need to overclock. Fortunately the q6600 is a good overclocker.

I can not believe, but it's true. I believed that the rate speed was dependent of the graphics card.
In this moment my bios was to default but i I had an overclocking profile saved to 3gh. I've enabled and the speed is in 90/100%

Thankyou, the speed it's ok now.

Again, sorry for my horrible English and thank you for all

Your cpu is too slow for efb copy to ram and LLE audio. You will need to overclock. Fortunately the q6600 is a good overclocker.

Indeed. EFB to RAM and LLE use the CPU, not the GPU.
