Bad performance in Zelda games

[TheShtank]

Hi,
Getting really bad performance in both Wind Waker and Twilight Princess. Twilight Princess has serious lag in outdoors, 9-17 fps. Wind Waker has laggy sound. Followed instructions for games on the wiki. Wondering if my computer should be able to handle these games. Are there any other methods to speed these games up?

Operating System: Windows 7 x64
Processor/CPU: IntelCorei7-3610QM CPU @ 2.30GHz, 2301 Mh
Video Card/GPU: AMD Radeon 7970M
Memory/RAM: 8GB
Dolphin Revision Currently Using: 4.0-4107

Thanks
