Hi I'm newbie with Pixi.js but already love it . Maybe it will sounds strange but some modern browsers on old machines tries to render a WebGL content with CPU instead of using the GPU acceleration and obviously the perfomance is poor (happen on old Chrome 36 and IE11) I'm asking for a method to check if the above is true and to switch the renderer into Canvas. And one more question - Is there a way to run somekind of a simple "stress" test to detect poor WebGL performance? Any help would be greatly appreciated. p.s. sorry for my bad English
