Mobile Chrome Slow Performance

[dearcj]

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

Sounds like you are falling back to the canvas renderer, even though you used to not fall back in v2. This is because v3 requires the Stencil Buffer in WebGL. Likely your device doesn't support it.

Ok, thanks

But in firefox WebGLRenderer version works fine

how can this be?

Also pixi says "Uncaught Error: This browser does not support webGL. Try using the canvas renderer" only in Chrome

Sounds like the Chrome version you are using doesn't support the stencil buffer like is required in v3.

Visit chrome://gpu in Chrome and it will tell you what features are hardware-accelerated. If a feature isn't hardware accelerated and there's no OS update for your phone, there's not a lot you can do other than change the flags in chrome://flags to force hardware acceleration, or just use a different browser...
