Just tried AssCreed 4, Vsync is borked? or has it been this way since launch? Constant 58 - 62 fps forced Vsync'ed on or Forced off via control Panel, with major stuttering when turning the camera or moving. 30 - 50 fps - Vsync on via in-game options. Same stutter. Shader Cache was on for the new drivers and also tried off. Performance was better with 331.82 EDIT: MSI Afterburner was the problem. Though FPS is still the same as with previous driver.
