SDL_HINT_FRAMEBUFFER_ACCELERATION

A variable controlling how 3D acceleration is used to accelerate the SDL screen surface.

Header File

Defined in SDL_hints.h

Syntax

#define SDL_HINT_FRAMEBUFFER_ACCELERATION   "SDL_FRAMEBUFFER_ACCELERATION"

Remarks

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.

This variable can be set to the following values:

• "0": Disable 3D acceleration
• "1": Enable 3D acceleration, using the default renderer.
• "X": Enable 3D acceleration, using X where X is one of the valid rendering drivers. (e.g. "direct3d", "opengl", etc.)

By default SDL tries to make a best guess for each platform whether to use acceleration or not.
