# SDL_HINT_MOUSE_RELATIVE_SCALING

A variable controlling whether relative mouse motion is affected by renderer scaling

## Header File

Defined in [SDL_hints.h](https://github.com/libsdl-org/SDL/blob/SDL2/include/SDL_hints.h)

## Syntax

```c
#define SDL_HINT_MOUSE_RELATIVE_SCALING "SDL_MOUSE_RELATIVE_SCALING"
```

## Remarks

This variable can be set to the following values:

- "0": Relative motion is unaffected by DPI or renderer's logical size
- "1": Relative motion is scaled according to DPI scaling and logical size

By default relative mouse deltas are affected by DPI and renderer scaling
