Sorry, I accidentally hit the reply button before finishing my post. I was under the impression that vidéo games for example explicitly allow to set the AA settings, with a default setting which usually is automatically depending on the hardware detected by the video game. Maybe it is possible to override them using the driver configuration, but I doubt many people do it.
As for WebGL, and also 3D games on iOS or Android, the problem is usually that these platforms have much less memory available than a desktop or laptop. And there are limitations to how using their available memory. See this post for example, I think it's interesting: http://www.bethblog.com/2010/10/29/john-carmack-discusses-rage-on-iphoneipadipod-touch/ Hervé 2013/7/20 John C.
