NAME
SDL_HINT_FRAMEBUFFER_ACCELERATION - A variable controlling how 3D acceleration is used to accelerate the
SDL screen surface.
SYNOPSIS
#include <SDL3/SDL_hints.h>
#define SDL_HINT_FRAMEBUFFER_ACCELERATION "SDL_FRAMEBUFFER_ACCELERATION"
DESCRIPTION
SDL can try to accelerate the SDL screen surface by using streaming textures with a 3D rendering engine.
This variable controls whether and how this is done.
The variable can be set to the following values:
• "0": Disable 3D acceleration
• "1": Enable 3D acceleration, using the default renderer. (default)
• "X": Enable 3D acceleration, using X where X is one of the valid rendering drivers. (e.g. "direct3d",
"opengl", etc.)
This hint should be set before calling SDL_GetWindowSurface()
AVAILABILITY
This hint is available since SDL 3.2.0.
