I've made a very simple VR/AR demo, using the see-through feature and a google cardboard viewer. I found that there is a small but noticeable lag between head movements and the camera feed, making the experience very unpleasant and nauseating. Basically the view is not realtime, but lags by about 100ms.
Am I doing something wrong, or is this just the state of the current tech?
I'm using Unity and running the app on a Samsung S6
