IE9 Tween performance

[shapevoid]

Hi my phaser tweens are running slow on IE9 (about half speed), regular game loop object movement via setting x/y is fine, IE10+ is ok as is other browsers.

 

Is there any known issue with phaser tweens and IE9?

 

Example of tween code

 

this.title.scale.set(0,0);

this.title.alpha = 1;

this.game.add.tween(this.title.scale).to({ x:1, y:1 },1500, Phaser.Easing.Elastic.Out, true, 500);

 

Any ideas?
