Do you think it’s possible that the jitter you’re still experiencing might look like this bug ?
Rigidbody intrepolation has some problems in Unity 2017.2 and .3, and it seems to depend a lot on the platforms/contexts. Sometimes it happens, sometimes it doesn’t. However, [mention|qztipHnpd7HujWyTg2eYuQ==] mentioned here that this might get fixed at some point in 2018.1 when PhysX3.4 arrives
I’d suggest making some very simple tests, like replacing the character controller with an extremely simple interpolated kinematic rigidbody that moves with your input, and see if you still get jitter with that same camera setup. You could also try your current setup in 2017.1 to see if that solves the problem
