Is there an easy way to do this without creating an xorg.conf just for one option? I've grown...weary...of FGLRX' shenannigans, but I can't get Vsync off using the Radeon driver - CS:Source for example is pinned at 59-60 FPS, even with vsync turned off in-game. Left 4 Dead 2 runs miserably, as vsync seems to still be enabled despite the explicit setting in the options (when it does get up to 60, it hovers right there). Unity is also in vsync, with the option turned off via CCSM.
