Vertical synchronization stops your video card from outputting frames faster than your monitor displays them, and thus prevents screen tearing. Vsync also effectively caps your frame rate and can induce input lag, making it a tradeoff. Triple buffering alleviates these negative features of vsync by storing an extra buffer of video data. Using a third buffer also requires more video memory and can cause display errors on programs that don't support it, so turning it off may help if your card doesn't work well with it on.
