Wind Waker

Hi hi. I'm playing Wind Waker on Dolphin 4.0.2 and am getting fps drops in a lot of scenarios, mostly combat. I've messed with all sorts of graphic and sound options without any success. Also, I just got to Dragon Roost and its very spiky looking. For the most part my settings are as low as possible right now. I'm using DSP LLE Recompiler, (read that this setting was significant), and can't change it to anything else. I downloaded something that enabled me to change it, but the game sounded awful. I'm also using Texture under EFB copies.

My specs:
cpu: intel i7 2600k
gpu: radeon hd 6950
ram: 16gigs


any advice is appreciated
