Now that we know Quantum Break won't be an Xbox One exclusive with the announcement of a release on the PC - with it being an exclusive to Windows 10 as it requires DX12 - we're finding out that it will not be on Steam, either.
Quantum Break will be a Windows Store exclusive according to Aaron Greenberg during the MajorNelson podcast. Greenberg said: "So, Quantum Break on Windows 10 is a Windows store exclusive". So while this is good, there were issues surrounding the Windows Store version of Rise of the Tomb Raider, so let's hope it doesn't happen with Quantum Break.
The Windows Store version of Rise of the Tomb Raider doesn't feature exclusive full screen support for SLI and Crossfire-based setups, and PC gamers aren't able to use third-party overlay programs like FRAPS or MSI Afterburner.
