A hint that specifies how 3D acceleration is used with SDL_GetWindowSurface().
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 whether to use acceleration or not on each platform.
SDL can try to accelerate the screen surface returned by SDL_GetWindowSurface() by using streaming textures with a 3D rendering engine. This variable controls whether and how this is done.
