Mouse movement shakes camera.

Before you downvote t$$anonymous$$s, yes, I have looked on all google answers, Vector Lerping is not the answer. And before you say it, float imprecision isn't it either.

I am making a solar system game but for some reason, the player movement isn't working well. I have the physics set up and the planets rotate around the sun, but for some reason, I cannot get the mouse movement working.

Currently, t$$anonymous$$s is what I have.

 yaw += Input.GetAxisRaw ("Mouse X") * 100 / 10 * mouseSensitivityMultiplier;
         pitch -= Input.GetAxisRaw ("Mouse Y") * 100 / 10 * mouseSensitivityMultiplier;
         pitch = Mathf.Clamp (pitch, pitchMinMax.x, pitchMinMax.y);
         float mouseSmoothTime = Mathf.Lerp (0.01f, maxMouseSmoothTime, 0.2f);
         smoothPitch = Mathf.SmoothDampAngle (smoothPitch, pitch, ref pitchSmoothV, mouseSmoothTime);
         float smoothYawOld = smoothYaw;
         smoothYaw = Mathf.SmoothDampAngle (smoothYaw, yaw, ref yawSmoothV, mouseSmoothTime);
         if (!debug_playerFrozen && Time.timeScale > 0) {
             cam.transform.localEulerAngles = Vector3.right * pitch;
             transform.Rotate (Vector3.up * Mathf.DeltaAngle (smoothYawOld, smoothYaw));
         }

I have maxMouseSmoothTime set at 0, (the shaking lasted longer when turned up) T$$anonymous$$s is what it looks like: https://www.youtube.com/watch?v=CvVlm2OuwOM
