isnt that one called compression just for marketing purposes? Afaik its a caching technique aimed at lowering latency cost of touching Zbuffer. It actually takes more ram than just raw non duplicated data.
- kevingadd 4y agoThe full resolution depth data doesn't always exist, which is why it can reduce bandwidth usage. It probably depends on the architecture, I've seen cases where there is no full resolution depth buffer and you have to generate one via decompression.
