# SDL_HINT_WINDOWS_RAW_MOUSE_NOLEGACY A variable controlling whether the RIDEV_NOLEGACY flag is set when enabling Windows raw mouse events. ## Header File Defined in [](https://github.com/libsdl-org/SDL/blob/main/include/SDL3/SDL_hints.h) ## Syntax ```c #define SDL_HINT_WINDOWS_RAW_MOUSE_NOLEGACY "SDL_WINDOWS_RAW_MOUSE_NOLEGACY" ``` ## Remarks If RIDEV_NOLEGACY is set, then Windows mouse events will not be sent for mouse motion while relative mode is enabled. This improves performance when players are using high DPI mice, but should be disabled while showing custom assert dialogs in your application code. Caution: Windows will not see mouse button releases in relative mode with this active. This means you should not enable relative mode while a mouse button is currently pressed. - "0": Windows mouse events will be generated while relative motion is enabled. (default) - "1": Windows mouse events will not be generated while relative motion is enabled. This hint can be set anytime. ## Version This hint is available since SDL 3.6.0. ---- [CategoryAPI](CategoryAPI), [CategoryAPIMacro](CategoryAPIMacro), [CategoryHints](CategoryHints)
