====== (This is the legacy documentation for stable SDL2, the current stable version; [https://wiki.libsdl.org/SDL3/ SDL3] is the current development version.) ====== = SDL_HINT_RENDER_DRIVER = A variable specifying which render driver to use. == 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_DRIVER "SDL_RENDER_DRIVER" == Remarks == If the application doesn't pick a specific renderer to use, this variable specifies the name of the preferred renderer. If the preferred renderer can't be initialized, the normal default renderer is used. This variable is case insensitive and can be set to the following values: "direct3d" "direct3d11" "direct3d12" "opengl" "opengles2" "opengles" "metal" "software" The default varies by platform, but it's the first one in the list that is available on the current platform. == Default == By default the first one in the list that is available on the current platform is chosen. ---- [[CategoryAPI]], [[CategoryAPIMacro]], [[CategoryDefine]], [[CategoryHints]]
