As for the performance freaks, you can enable Ultimate mode which is right at the bottom of the "ASUS customizedsetting" menu, but we didn't notice any performance gain during our benchmark tests.
Still, for some weird reason, only a portion of the bundled apps have Dynamic Display switch enabled by default, so users will need to go into "ASUS customizedsetting" in system settings to choose more apps.
The only interface customization you'll find here are the thumbnail overview of up to seven home screens (pinch anywhere on any home screen to toggle), as well as the "Pad Only" tab in the app drawer, the handy ASUS Quick Setting panel in the notification tray, and "ASUS customizedsetting" in system settings.
