* gles1/gles2 support and renderers are disabled by default and can be enabled by configuring with `-DVIDEO_VITA_PVR=ON`

These renderers support 720p and 1080i resolutions. These can be specified with:

`SDL_setenv("VITA_RESOLUTION", "720", 1);` and `SDL_setenv("VITA_RESOLUTION", "1080", 1);`

* Desktop GL 1.X and 2.X support and renderers are also disabled by default and also can be enabled with `-DVIDEO_VITA_PVR=ON` as long as gl4es4vita is present in your SDK.
|

They support the same resolutions as the gles1/gles2 backends and require specifying `SDL_setenv("VITA_PVR_OGL", "1", 1);`

* gles2 support via PIB is disabled by default and can be enabled by configuring with `-DVIDEO_VITA_PIB=ON`

* By default SDL emits mouse events for touch events on every touchscreen.

Vita has two touchscreens, so it's recommended to use `SDL_SetHint(SDL_HINT_TOUCH_MOUSE_EVENTS, "0");` and handle touch events instead.

OpenGL ES 2.x support
|

================================================================================
|
||||
## LLVM and Intel C++ compiler 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
|
||||
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.
|
||||

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.
|

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)
|
||||
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).
|
||||
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).

|
||||
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.
