Battlefield 1 sample profile for PS4:

[updated 10/2/17]

Battlefield 1 has numerous in-game sensitivity options, but start with the default settings except as noted below and adjust as needed. Testing in campaign mode is a good way to get the basic settings adjusted before you start tweaking for multiplayer mode.

The attached profile was made for the following in-game settings:
Soldier Stick Sensitivity: 100%
Vehicle Stick Sensitivity: adjust as needed
Soldier Zoom Sensitivity: 200%
Advanced Settings:
Stick Aiming Acceleration: 0%
Left and Right Stick Center Deadzone: 22% (Default)
Axial Deadzone: 15% (Default)
Max Input Threshold: 100%
Uniform Soldier Aiming: Off

Please keep in mind that each multiplayer class plays differently and creating/tweaking profiles for individual classes may help you get the most out of your weapon choices.
