It’s not news that many PC users are reluctant to use the Windows 10 Store to buy Microsoft exclusive titles. Quantum Break was also one of those Windows 10 Store exclusive titles, but now the game is available on Steam too. As expected, Quantum Break works much better in the new version of Steam, as it only runs with DirectX 11.

The game on Steam throws up to 33 percent extra performance in the case of NVIDIA. With AMD hardware, specifically with the RX 480, no additional benefits. The graphics difference between both versions is negligible.
