Microsoft is getting serious about virtual reality gaming, announcing at the E3 conference Monday that it will be working with Valve VR to bring virtual reality to Windows 10. This comes a week after Microsoft announced a partnership with Oculus VR, which will see an Xbox One controller ship with all headsets and give gamers the ability to stream 3D titles from their Xbox One.

While it is not yet clear what Microsoft and Valve are working on, Microsoft's Kudo Tsunoda did say his company "will be working closely with Valve to make Windows 10 the best platform for VR gaming."

Valve partnered with HTC on its VR headset, the HTC Vive, which they announced at the Mobile World Congress in March. It is set to be released for the 2015 holiday season, while the Oculus is slated for an early 2016 release.

These partnerships are in addition to Microsoft's own augmented reality efforts with its HoloLens device.
