With the launch of Xbox One being only a month away, or 43 days if being exact is your sort of thing, more news is coming out about the console. This time, it relates to the DVR feature.
Currently with Xbox One, the DVR will keep the past five minutes of whatever you’re doing, recorded. However, this recent announcement has confirmed that if a player unlocked an achievement, it will automatically record achievement unlocks for you and offer share options.
Sadly, this is up for the developer, if they chose to disable this feature then you will have to record your own achievements.
