UPDATE: Microsoft has said Quantum Break is now the best-selling new Microsoft Studios IP this generation, as well as being the best-selling boxed game in the UK this week.

That means it's outsold the week one sales of the likes of Insomniac's Sunset Overdrive and Crytek's Ryse, both new Microsoft Studios IP that launched this generation.

ORIGINAL STORY: Quantum Break is the UK's best-selling boxed game.

While Remedy's action shooter is out on Windows 10 and Xbox One, sales tracked by Chart-Track are for the Xbox One version only. Chart-Track does not include download sales in its report.

Quantum Break only just beat Codemasters' Dirt Rally to top spot. Dirt Rally launched on PC, PlayStation 4 and Xbox One last week, and Quantum Break's single platform sales beat it by just 139 sales.

Chart-Track said Dirt Rally beat launch week sales of 2012's Dirt Showdown by 197 per cent. But it's third in launch week sales terms compared to other games in Dirt series, behind Colin McRae: Dirt 2 and Dirt 3.

Here's the top 10:
