More details are appearing on the Oculus Go, a standalone mobile VR headset that is being developed, after Oculus spoke at the GDC. The headset will have a single 2560 x 1440 LCD display with ‘fast fill’ (a term describing low latency) and Oculus said that there is a 72Hz mode that can be engaged if the app can make the most of it, by processing fast enough. Oculus is also recommending that developers use ‘fixed foveated rendering’ i.e. assuming that the viewer is looking at the centre of the display and reducing resolution outside the central area. Most of the display area is considered as full resolution, but other areas are rendered at 1/2, 1/4, 1/8 and 1/16 resolution.
At the event, Oculus said that it had worked with Qualcomm, which is supplying the Snapdragon 821 processor for the Go, to optimise performance for this kind of process.
