==Platform Layers Backends== | |||
If you're finding yourself unaccelerated, you can use <code>layers.acceleration.force-enabled</code> to force layers acceleration. | |||
===Windows=== | |||
Available Layers backends: D3D10*, D3D9, OGL*, Basic | |||
Our default here is D3D10, but as D3D10 is not available on Windows XP, XP defaults to D3D9. | |||
While there's no technical reason OGL Layers cannot work on Windows, it is not a supported configuration, and (at present) does not seem to render properly. | |||
*Enabled D3D9 Layers with <code>layers.prefer-d3d9</code> | |||
*Enabled OGL Layers with <code>layers.prefer-opengl</code> | |||
===Mac=== | |||
Available Layers backends: OGL, Basic | |||
Our default is OGL. | |||
===Linux=== | |||
Available Layers backends: OGL, Basic | |||
Our default is theoretically OGL, but it is blacklisted basically universally on linux. | |||
In practice, you'll find Basic Layers is the default here, but you can use force-enable Layers acceleration to use OGL layers. | |||
==Platform GL Providers== | |||
WebGL can be force-enabled with <code>webgl.force-enabled</code>. | |||
===Windows=== | |||
By default, we don't actually run on the machine's native OpenGL libraries, but rather on ANGLE, which in turn runs on D3D9. | |||
ANGLE provides an implementation of GLES2 on top of EGL. | |||
However, running on the machine's native OpenGL implementation on top of WGL is possible with <code>webgl.prefer-native-gl</code>. | |||
===Mac and Linux=== | |||
Mac and Linux are very similar, in though mac is provided on top of CGL, and Linux is generally provided on top of GLX. | |||
