Camera doesn't move smoothly at 60fps

When I’m running my game with Application.targetFrameRate = 60 I find that every once in a while the camera feels like it lags a bit behind where it should be and then jumps to its appropriate position (and the fps is remaining at 60). However when I run my game with Application.targetFrameRate = 80 this goes away completely. What does this suggest? Is there anything I can do to fix this for 60 fps? I’m currently using Unity Asset Store - The Best Assets for Game Making

I prefer using FixedUpdate. Since it keeps its pace regardless of your current framerate, it’s usefull for fixing camera follow shaking, like you’re experiencing
