Evelop's press release says their Windows VR app has been in closed beta testing for the past several months. It adds:
Users can open multiple windows, adjust them to any size, and place them wherever they want, improving multi-tasking capabilities and allowing for customization of a personal work space for improved productivity and efficiency while computing. Virtual reality users can now shop online, check social media, work in Microsoft Office and watch a YouTube video all at the same time.
The app itself will be released for free via Steam. It will require a PC with Windows 10 installed, along with a GPU similar to or better than an NVIDIA GeForce GTX 970 or AMD Radeon R9 290.
