Thus far, the virtual reality ecosystem has focused almost exclusively on single-user experiences. A few developers have made attempts to use things like HTC's Vive Tracker to bring additional participants without VR headsets into the main user's VR experience. Nvidia has now shown off a proof-of-concept system that uses virtualized hardware to bring four headset-wearing participants into a common VR experience.
The system uses four of Nvidia's Quadro P6000 graphics cards. For those that don't lull themselves to sleep by reciting Quadro model numbers, the P6000 is based on the same GP102 silicon inside the almighty GeForce GTX 1080 Ti and GeForce Titan Xp. The setup uses four of HTC's Vive Business Edition headsets and a single physical machine with four VMs. Thankfully, only one set of Lighthouse tracking beacons are required. No other details were provided, though we imagine the CPU and memory requirements are both "gimme all you got."
Multi-user VR opens up new possibilities for entertainment and productivity software. Nvidia's blog describes possible applications in amusement parks as well as in military and first-responder training. Nvidia's software partners MonsterVR and CAVRNUS are both showing off applications based on the multi-user hardware at GTC.
