I asked a question a while ago:
And the answer I got was to put my camera movements in a fixed update. How would I do that. And does someone have a better answer for my previous question?

Update is called every frame that's drawed. FixedUpdate is called at fixed intervals (you can define the interval in Edit -> Project Settings -> Time -> Fixed Timestep). It's used internally for Physics and a good place for putting things that should be framerate independent. For example if you made a simple counter and put it in Update it will count slower when framerate drops, not when put in FixedUpdate.
