FPS controller camera objects "Jitter" when camera moves and looks around (standard assets))

hi I’m using the standard assets FPS controller, I have done nothing to it but make you run faster. when u walk around and move the mouse at the same time the scene “Jitters” and is not smooth, can’t seem to find a fix anywhere thanks.

If you can give a video I should be able to help. I think I stumbled across the answer looking for something else.
