Hi I've being making games with pixi for a quite time And now when I've moved from pixi 2 to pixi 3.0 I got super slow performance with my Samsung Galaxy S4 Mobile Firefox is fast I got about 30-40 fps And I got 10 fps in Chrome I thought that the problem could be in requestAnimationFrame call So I've used this function window.requestAnimFrame = function(){ return ( window.requestAnimationFrame || window.webkitRequestAnimationFrame || window.mozRequestAnimationFrame || window.oRequestAnimationFrame || window.msRequestAnimationFrame || function(/* function */ callback){ window.setTimeout(callback, 1000 / 60); } ); }(); And there is still low performance in chrome Also if I'm using PIXI.WebGLRenderer instead of autoDetectRenderer it's not working, and I got black screen on my S4 and firefox doing fine
