Wind Waker heavy lag in combat

[BladeY2J]

My apologies if I post this in the wrong place I just created an account. Wind Waker was probably my favorite Zelda ever. Last night I was very excited to play. I soon learned however that whenever I use my sword to strike down anything (be it a tree or bush or whatever) that the FPS drops to about 24-25. The same thing happens when I get near a potential combat situation like approaching and enemy who mans the lights at the forsaken fortress for example. Now, I have a pc where I can play battlefield 4 with max graphics with no problems whatsoever (aside from it being a glitchy game in general) so I imagine if there WAS a way to run my Wind Waker game on dolphin with no lag my computer should be able to do it. I realize that emulators use more CPU or whatever (bear with me I'm really bad at this vocabulary I'm not much of a programmer). When I'm not in combat situations my computer runs at like 30-32 fps but when I get near enemies or strike something down it drops to 25 fps and the audio gets... bumpy (cuts in and out all strobe like). I wasn't entirely sure of my specs because I'm at school on my laptop so I threw things out there I believe are on my desktop so if I need to post it let me know... I'm not sure how to send the pictures of what settings I'm using on Dolphin yet either but if you need that too I'll post it when I get home. I would REALLY REALLY appreciate help from you smart people out there. I love this game it would be a dream to be able to play it again without these problems. Has anybody been able to set it up without any lag problems that you could post? Thank you!!
