Razer has announced its second Open Source Virtual Reality (OSVR) headset. Dubbed HDK2, the new headset from the gaming-hardware company is priced at $400. As for the specifications, the HDK2 offers dual OLED display of screen resolution 2,160x1,200 pixels while retaining the 90hz low-latency refresh rate. The original HDK will continue to be available for purchase at $300. On the sidelines, the company announced a $5 million to studios working in this space. AnandTech reports: OSVR has an open framework so it will be able to work with a variety of controllers, and as more control mechanisms become available, it should be able to support them. The HDK system supports several content technologies, including SteamVR, and they plan to announce more content soon. On that note, OSVR is also announcing a $5 million developer fund. Their goal is to ensure unrestricted access of VR content on all hardware. If you are a VR content developer, you can apply to this fund. If approved by the fund, and OSVR support is added to the content, Razer, or other future contributors, will purchase game codes in bulk to help compensate developers for their integration time, and the fund will also assist with marketing and promotional support.Also at E3, Sony announced that its $399 PlayStation VR wil be available to purchase in the U.S. from October 13.
