Some games have an in-game setting to set triple buffering. It's best to enable it from there, when possible.
Also, note that triple buffering increases the input lag a little. When playing games that don't require extreme responsiveness (e.g.: MMOs, RPGs, among others), it's completely unnoticeable, thus having it on is usually a Good Thing™ there. On the other hand, when playing games that do require
extreme responsiveness (competitive shooters, mostly), it is best to avoid it, as the input lag becomes noticeable and really annoying at times.
