Latest Radeon software improves Vsync for 'liquid-smooth gaming'
...
......
Most recently AMD has been touting an additional software solution that they believe can enhance what Vsync already provides.
Enhanced Sync enabled games can run with an uncapped frame rate and still experience the same tear-free gaming that Vsync offers. Enhanced Sync does not replace Vsync, but rather works with it.
“Enhanced Sync disables Vsync when frame rate drops below a monitor’s refresh rate, thereby minimizing stutter. Enhanced sync technology delivers liquid-smooth gameplay by focusing on latency at a low framerate.”
