But this adapter requires not only DisplayPort and USB 3.0, but also an AC power brick. We expect all PC VR companies will include such an adapter- it wouldn’t make business sense to only support RTX GPUs. The spec defines an adapter for using a VirtualLink headset with a PC lacking the port. Oculus Support tells these users to buy a USB PCI-E card from Amazon with a compliant controller.īut for buyers without a VirtualLink GPU, these kinds of USB issues could very well happen again. That’s because many USB controllers on motherboards simply don’t comply with the USB spec properly. With the Oculus Rift, many users encounter USB bandwidth issues with the tracking sensors. Furthermore, VirtualLink GPUs must include a standards compliant USB controller for this data. That’s more power than three USB 3.0 ports would provide, and as much data as two would. One dedicated port for VR replaces the many of the past.īut it’s the sheer amount of power & data that really matters- a minimum of 15 Watts of power and 10 Gbit/sec of USB data. VirtualLink will provide video, audio, data (USB), and power all through the single cable and port. All the major PC VR players are onboard- and it’s an open standard. The famous xkcd comic about new standards doesn’t apply here. So VirtualLink isn’t some proprietary NVIDIA offering. The standard was founded back in July by Oculus, Microsoft, Valve, NVIDIA, and AMD. It also allows gaming laptops to guarantee VR support- and perhaps even smartphones and tablets one day.īut why does it matter? Full Industry Support It’s intended to simplify the setup process of VR and ensure compatibility with USB and power requirements of future headsets. VirtualLink is the new USB-C single cable standard for future VR headsets and the GPUs/laptops they connect to.
