Gamers who are part of the Xbox One preview program will be well versed in the new Xbox One snap achievements application which for the first time allows for true achievement progress tracking. We put the app to the test to see how the achievement update works and found the app updates the progress  immediately. Whilst this has always happened in the background, to view has  required users to go through a loading process to access the page, at least now progression can be viewed in real time. Take a look at the video which demonstrates this in action.
