There are sensitivity settings in the main and pause menu! Also the game was designed and tuned to be played with a controller! Yes I've heard that feedback for mouse and keyboard users for sure. Tune using the settings and hopefully you can have a better experience.
that's very strange! At the lowest setting the camera shouldn't even move technically. It would make the sensitivity 0. Sorry you're having that experience. I'll do some troubleshooting to see if I can find a cause.
