I work on the renderer for a product that uses WebGL (I won&#x27;t link to it because I don&#x27;t want to sound like a shill, but it&#x27;s a web based 3d modeler called FormIt).<p>Unfortunately, I think webgl performance has actually been getting much worse on Chrome. (Firefox has been fine).<p>WebGL is pretty exciting in what it makes possible, but it&#x27;s based on the OpenGL ES2 spec from 2007 which is way out of date at this point, so the surface area of the hardware you can actually use is really limited, and various aspects of javascript lead to some really ugly performance compromises. This is partially why I&#x27;m pretty excited about web assembly -- I don&#x27;t think it&#x27;ll fix everything off the bat, but not having to go through javascript could be a really big win.
