Animal Crossing laggin on an AMD Nitro 5

So, I downloaded Citra this afternoon because I really wanted to play Animal Crossing New Leaf, when I went to play I realized a horrible performance in the game, I moved in quite a few settings and for the moment nothing solved. What I noticed in a few minutes of gaming is that in moments inside houses and other closed places the FPS goes like what I expect, but in open regions it is always 50% or worse. Anyway, there goes some screenshots for better understanding.
PS: I`m brazilian so, my English is not perfect and my Citra language is on portuguese. Thank you for the Attention <3
