how would I smooth character movement

Hello,
I am trying to make my VR character (from the VR template) move. right now I have been using addActorLocalTransform. I have tried to use addMovementInput, but it would not work for me. The local transform seems to work except when the transform goes to above 15 or so units per second. is there any way I could make this transition smoother, it is very sickening in VR!

Thanks,
