Foveal rendering is in a weird spot. The software seems to be there, but mostly only in academia. The hardware is almost nowhere to be found, because it is another expense. People prefer spending that extra money on a better computer, since that improves every VR experience, not just the possibility of (part of) future experiences.

FVR needs a hook: what can it do that "dumb" VR headsets don't?
