This seems fixed in Ubuntu 14.04 (Unity 7.2.1). I'm running a full-HD and quad-HD monitor from an ASUS Z97 Pro motherboard with an Intel core i5-4430 CPU. I'm using an nVidia GeForce 660TI GPU with the proprietary 337.25 beta driver. Everything is awesomely smooth and responsive.
The only time things become jerky and stuttery again is when I open a video in Ubuntu's default video player (Totem?). If I use VLC, however, things remain ultra smooth and responsive. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to compiz in Ubuntu. https://bugs.launchpad.net/bugs/1007857 Title: window animations are far from smooth Status in Compiz: Confirmed Status in “compiz” package in Ubuntu: Confirmed Bug description: Window animations (e.g. when you maximize/minimize a window) are very, very jerky. Note they are not slow, it's just they are not smooth. My computer has definitely enough CPU and GPU power to render those animations smoothly, and this happens even when there's no program using significant system resources. This defeats the very purpose of those animations, which is to provide a more fluid user experience. I know they are a mostly aesthetic feature and I am the last person who would like to see such a feature take resources from more important things, but either they can be made decently smooth without affecting system performance, or they cannot, in which case they should be removed altogether. No window animation is _way_ better than a jerky window animation.
