I haven't heard of anyone doing visibility buffers on mobile yet.

For a while forward rendering made a comeback with clustered shading and VR, and conventional wisdom was that deferred was too slow for mobile.

These days it seems like every renderer I hear about is deferred, even on mid-range mobile. Is that actually the trend?
