 # Windows

 ## LLVM and Intel C++ compiler support

 SDL will build with the Visual Studio project files with LLVM-based compilers, such as the Intel oneAPI C++
 compiler, but you'll have to manually add the "-msse3" command line option
 to at least the SDL_audiocvt.c source file, and possibly others. This may
 not be necessary if you build SDL with CMake instead of the included Visual
 Studio solution.

 Details are here: https://github.com/libsdl-org/SDL/issues/5186


 ## OpenGL ES 2.x support

 SDL has support for OpenGL ES 2.x under Windows via two alternative
 implementations.

 The most straightforward method consists in running your app in a system with
 a graphic card paired with a relatively recent (as of November of 2013) driver
 which supports the WGL_EXT_create_context_es2_profile extension. Vendors known
 to ship said extension on Windows currently include nVidia and Intel.

 The other method involves using the
 [ANGLE library](https://code.google.com/p/angleproject/). If an OpenGL ES 2.x
 context is requested and no WGL_EXT_create_context_es2_profile extension is
 found, SDL will try to load the libEGL.dll library provided by ANGLE.

 To obtain the ANGLE binaries, you can either compile from source from
 https://chromium.googlesource.com/angle/angle or copy the relevant binaries
 from a recent Chrome/Chromium install for Windows. The files you need are:

 - libEGL.dll
 - libGLESv2.dll
 - d3dcompiler_46.dll (supports Windows Vista or later, better shader
   compiler) *or* d3dcompiler_43.dll (supports Windows XP or later)

 If you compile ANGLE from source, you can configure it so it does not need the
 d3dcompiler_* DLL at all (for details on this, see their documentation).
 However, by default SDL will try to preload the d3dcompiler_46.dll to
 comply with ANGLE's requirements. If you wish SDL to preload
 d3dcompiler_43.dll (to support Windows XP) or to skip this step at all, you
 can use the SDL_HINT_VIDEO_WIN_D3DCOMPILER hint (see SDL_hints.h for more
 details).

 Known Bugs:

 - SDL_GL_SetSwapInterval is currently a no op when using ANGLE. It appears
   that there's a bug in the library which prevents the window contents from
   refreshing if this is set to anything other than the default value.

 ## Vulkan Surface Support

 Support for creating Vulkan surfaces is configured on by default. To disable
 it change the value of `SDL_VIDEO_VULKAN` to 0 in `SDL_config_windows.h`. You
 must install the [Vulkan SDK](https://www.lunarg.com/vulkan-sdk/) in order to
 use Vulkan graphics in your application.
