A variable that controls whether the device's built-in accelerometer and gyro should be used as sensors for gamepads.
Defined in <SDL3/SDL_hints.h>
#define SDL_HINT_GAMECONTROLLER_SENSOR_FUSION "SDL_GAMECONTROLLER_SENSOR_FUSION"
The variable can be set to the following values:
Or the variable can be a comma separated list of USB VID/PID pairs in hexadecimal form, e.g.
0xAAAA/0xBBBB,0xCCCC/0xDDDD
The variable can also take the form of "@file", in which case the named file will be loaded and interpreted as the value of the variable.
This hint should be set before a gamepad is opened.
This hint is available since SDL 3.1.3.
