Two significant hurdle that virtual reality displays have had to overcome are latency and persistence. If there’s too much delay between the movement of a user’s head and a corresponding change on the head-mounted display, or too much image persistence between frames, the user will likely feel nauseous. The Oculus Rift and HTC Vive already employ 90Hz, low-persistence displays to counteract this problem, but Nvidia thinks it can all but eliminate display latency by pushing the refresh rate even higher. At GTC 2016, Nvidia demoed a prototype display that runs at about 1700Hz.
To demonstrate this technology, RoadToVR says Nvidia attached a VR display to a rail system and shook it back and forth rapidly. The image on the display stays in the same position relative to the camera. The logo stays visible with only a small amount of blurring, despite the rapid movement. The presenter, Nvidia’s Vice President of Research David Luebke, says that Nvidia attains this high refresh rate by "overloading the display and driving it with this kind of novel binary delta-sigma encoder kind of approach." The company didn't indicate when this display tech might make its way out of the lab.
