This was in Nvidia settings guide site:
Triple Buffering:if set to On, this setting allows your overall performance to improve when Vertical Synchronization (VSync) is enabled in games. Therefore if you want to enable VSync - whether in the in-game settings or in the Nvidia Control Panel, it is recommended you enable Triple Buffering as well. However note that using Triple Buffering may cause problems for graphics cards with lower Video RAM, so disable this option if you’re experiencing problems such as mouse lag in games. Note further that this option only works for OpenGL games at the moment, so to force Triple Buffering in Direct3D games (which is the majority of recent games), see the Advanced Tweaking section.
