(This is the legacy documentation for stable SDL2, the current stable version; SDL3 is the current development version.)

SDL_HINT_RENDER_VSYNC

A variable controlling whether updates to the SDL screen surface should be synchronized with the vertical refresh, to avoid tearing.

Header File

Defined in [SDL_hints.h](https://github.com/libsdl-org/SDL/blob/SDL2/include/SDL_hints.h), but apps should _only_ `#include "SDL.h"`!

Syntax

#define SDL_HINT_RENDER_VSYNC               "SDL_RENDER_VSYNC"

Remarks

This variable can be set to the following values: "0" - Disable vsync "1" - Enable vsync

By default SDL does not sync screen surface updates with vertical refresh.

Default

By default SDL uses the SDL_RENDERER_PRESENTVSYNC flag passed into SDL_CreateRenderer().
