i'm trying improve performance on our canvas (multiple areas) being redrawn on every stage.update() , how works. i'd draw / add single area. can work, previous areas removed because of update . found caching might performance improvement, slows rendering down. example code: self.areamask = new createjs.shape(); self.areamask.graphics.beginfill("#000").drawrect(0, 0, 50, 50); self.areamask.cache(0, 0, 50, 50); the weird part moment enable caching, makes rendering slower. when decrease optional fourth scale parameter 0.1 performance is, slightly, better. i'd understand how possible, doing wrong? is there better way desired behaviour? (only draw / add specified areas, don't redraw areas) caching improve things in browsers, provided: the browser can put content on gpu. if can not, cpu used draw images, can slower. browsers work fine in cases, see opposite effect. example, easeljs cache demo performs worse in safari, despite working bet...
