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

+## 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.
