NAME
       SDL_HINT_VIDEO_DOUBLE_BUFFER - Tell the video driver that we only want a double buffer.


HEADER FILE
       Defined in SDL3/SDL_hints.h


SYNOPSIS
       #include "SDL3/SDL.h"

       #define SDL_HINT_VIDEO_DOUBLE_BUFFER SDL_VIDEO_DOUBLE_BUFFER"


DESCRIPTION
       By  default, most lowlevel 2D APIs will use a triple buffer scheme that wastes no CPU time on waiting for
       vsync after issuing a flip, but introduces a frame of latency. On the other hand, using a  double  buffer
       scheme  instead is recommended for cases where low latency is an important factor because we save a whole
       frame of latency.

       We do so by waiting for vsync immediately after issuing a flip, usually just after eglSwapBuffers call in
       the backend's *_SwapWindow function.

       This hint is currently supported on the following drivers:

       • Raspberry Pi (raspberrypi)

       • Wayland (wayland)

       This hint should be set before SDL is initialized.


AVAILABILITY
       This hint is available since SDL 3.2.0.
