Hello,
The in-game gyro aiming is broken. Currently, the aiming feels similar to controlling a joystick, whereas gyro should more closely resemble mouse movement.
Removing the speed limit and smoothness could fix this issue.
There is a workaround with Steam Input, which allows gyro to function as a mouse. However, this workaround disables DualSense features such as haptic feedback.
So a second solution would be to allow mixed input.
