If you edit the FirstPersonControls component to with the below, then create a prefab using it, the mouse look will be sluggish. I've spent 4 hours last night trying to figure this out and I can confirm this is a bug with the prefab system. If you were to assign this to an entity normally, it'll work fine.
The Raw mouse code tends to work ok regardless.
