Baldur's Gate: Dark Alliance Problem Help

[talos91]

Using one of the latest development builds I can play the game at 100% speed but for some reason the fps is really really low(see image), anyone knows the best settings to fix this? Btw this also happens in dolphin 4.0.2.

I am using windows 7 64 bits Intel Core i5-2430M, 2.4GHz 8gb ram.
