01:00.0 VGA compatible controller: ATI Technologies Inc Juniper [Radeon HD 5700 Series]
I have ATI's 5770 with fglrx. Having "Sync to Vblank" on makes Unity and many Compiz features (Enhanced Zoom, Scale etc.) really slow. Turning "Sync to Vblank" off has a huge effect on desktop, responsiveness is much, much better. Turning "tearing" off/on from amdccle doesn't seem to have any effect on responsiveness.
In Maverick "Sync to Vblank" was off by default, in Natty it's on. This will probably have a huge impact on many fglrx users.
Package: fglrx
Version: 2:8.840-0ubuntu2
