Now how to check that ANGLE is disabled? Just use this WebGL Browser Report app. Unlike Firefox, you need to close all Chrome instances to enjoy the new setting. Just edit the Chrome shortcut and change the Target value: In Chrome, you have to add the following command line parameter: –use-gl=desktop. And by default, webgl.disable-angle is set to false: native OpenGL is not used. In recent version of Firefox, the webgl.prefer-native-gl variable has been replaced by webgl.disable-angle. The nice thing with Firefox, is that the new setting is immediately operational. In Firefox, just set the webgl.prefer-native-gl variable to true in the about:config page: If, for some reasons (for some Shadertoy demos for example), you want to use real OpenGL draw calls, you can enable native OpenGL in Firefox and Chrome.

ANGLE is an implementation of the OpenGL ES 2.0 specification that is hardware-accelerated via Direct3D 9. By default, both Firefox and Chrome use the ANGLE layer to render WebGL draw calls under Windows.
