For Swerve http://swerve.playcanvas.com/ http://swerve.playcanvas.com/ we designed the UI to be responsive for desktop and mobile. We're using HTML/CSS for this so it works well, but unfortunately you end up getting some stalls for browser layout and compositing. For Swerve this is a problem because we're aiming for smooth 60fps but in a less twitch-based game this wouldn't be so much of an issue.
