In Firefox and Chrome it should use requestAnimationFrame whose role is to defer to the browser the choice of the frame rate so that it stays responsive See https://developer.mozilla.org/en/DOM/window.requestAnimationFrame and http://code.google.com/p/google-web-toolkit/source/browse/trunk/user/src/com/google/gwt/animation/Animation.gwt.xml (and http://code.google.com/p/google-web-toolkit/source/browse/trunk/user/src/com/google/gwt/animation/client/AnimationSchedulerImplTimer.java which uses a timer that tries to achieve 60Hz frame rate) If your animation is not smooth, it's probably that it doesn't run at approx. 60Hz, which means that either your code in the animation or some other code runs too slowly to achieve that rate. Because timers and requestAnimationFrame (and basically everything in a browser) go through the event loop and task queues < http://www.whatwg.org/specs/web-apps/current-work/multipage/webappapis.html#event-loops> it can be that something else than the animation is pushing too many tasks in the queue and/or that those task run slowly, delaying other tasks and therefore prevent reaching the 60Hz target rate. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
