A variable controlling whether the system mouse acceleration curve is used for relative mouse motion.

Header File

Defined in SDL_hints.h

Syntax

#define SDL_HINT_MOUSE_RELATIVE_SYSTEM_SCALE    "SDL_MOUSE_RELATIVE_SYSTEM_SCALE"

Remarks

This variable can be set to the following values:

• "0": Relative mouse motion will be unscaled (the default)
• "1": Relative mouse motion will be scaled using the system mouse acceleration curve.

If SDL_HINT_MOUSE_RELATIVE_SPEED_SCALE is set, that will override the system speed scale.
