Animations can be used for good or evil. They can either create rich and compelling experiences that help users understand and use the application, or they can demonstrate just how truly awful the performance of your application is as they stutter and jank all over the screen. "Turn it off! Turn it off!" your users will scream. But there's a better way. Graphics performance is at the heart of smooth and seamless animations: optimize your rendering performance and you can turn your users on instead of having them turn you off.
