 ## Renderers and Browser Support
 
-By default, OpenLayers uses a performance optimized Canvas renderer. An experimental WebGL renderer (without text rendering support) is also available.
+By default, OpenLayers uses a performance optimized Canvas renderer.
 
 OpenLayers runs on all modern browsers that support [HTML5](https://html.spec.whatwg.org/multipage/) and [ECMAScript 5](http://www.ecma-international.org/ecma-262/5.1/). This includes Chrome, Firefox, Safari and Edge. For older browsers and platforms like Internet Explorer (down to version 9) and Android 4.x, [polyfills](http://polyfill.io), the application bundle needs to be transpiled (e.g. using [Babel](https://babeljs.io)) and bundled with polyfills for `requestAnimationFrame`, `Element.prototype.classList` and `URL`.
