    Currently there's a deferred AO in cinematic post. I'm not sure what plans @Tim C has here, perhaps he could input?

    In any case I think this would be considerably slower on mid range desktop and consoles.

    That "Screen-Space AO" screenshot in the linked post looks way worse than any SSAO I've seen, a bit disingenuous using it to effectively market their new AO IMO. The new Cinematic AO is actually the most impressive image effect out of all the new ones, simply because it can run so fast - as in, it can become as cheap as bloom depending on your settings.

    it will only get better with temproal AA as it will smooth out sampling issues (basically we get more samples as we can use last frames sample results, how awesome is that!)

    I think you're misinterpreting the "3x faster" comment in the slides for VXAO. They say it's "3x faster" than their full voxel lighting solution including real time global illumination, not 3x faster than SSAO. It's about 10x slower than a modern screen space AO if you take into account the required scene voxelization time.

    Yes I was thinking that. Must be slower since there is much more shadow information and shadow quality. Thanks for pointing it out.
