I'm sorry if this sounds more exciting than it is.
Press J + O on the main menu to go to the joypad calibrations window.
Flick stick is smoothed now.
This game now uses the natural scale and no this is not something to do with a certain avian/dinosaur with a love of calibrating. This means that for a 360 degree turn of the pad, Della turns 360 degrees if the in game sensitivity is set to 1.0, at 2.0 Della turns 720 degrees, etc.
Here are my calibrations for a 360 degree joypad turn. J + O on the main menu and look at the Turn value.
PS4Controller 165000
PS5Controller 89500
SwitchProController 180000
SteamController 80800
The SteamInput Configurations need to be updated to the new ones by selecting the recommended config via the Buttons menu item. Or you can adjust the SteamInput Gyro Sensitivity to Max 1.0.
Your calibrations are welcome.
