Accuracy of the sensor bar on Dolphin

[muccmin2]

i play house of the dead and another gun game with my pistol shot gun, the cross hire on my screen isn't stable, it jitters allot, making it hard to aim accurately. im trying to figure out how to set it up so it stays smooth and stable like the real wii if its possible, it works well but it doesn't help accuracy when aiming and shooting. It's still very playable and fun just wondering if i have to set it up in the IR options of the wii mote plugins
