(This is the documentation for SDL3, which is the current stable version. SDL2 was the previous version!)

SDL_HINT_MOUSE_RELATIVE_SYSTEM_SCALE

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

Header File

Defined in <SDL3/SDL_hints.h>

Syntax

#define SDL_HINT_MOUSE_RELATIVE_SYSTEM_SCALE "SDL_MOUSE_RELATIVE_SYSTEM_SCALE"

Remarks

The variable can be set to the following values:

• "0": Relative mouse motion will be unscaled. (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.

This hint can be set anytime.

Version

This hint is available since SDL 3.1.3.
