Wiimote lag

[OOmhp]

I'm using a real wiimote with a USB bluetooth adapter, with Toshiba stack v9.10.15T, and Dolphin v4.0.2. Everything works perfectly fine for one of my computers (i5-3570k, Radeon 7950, 8gb ram), however, for some reason i'm finding a slight wiimote delay playing the same games under the same exact settings for my other computer (i5-4670k, Radeon 7870, 8gb ram). It's hard for me to believe computer specs are the issue since the processor would seem to be a little bit better, and the video card much more powerful than needed. Any ideas as to what could explain the difference?
