+## 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

 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)

 d3dcompiler_* DLL at all (for details on this, see their documentation).

-    * 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

+## 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.
