He talked about their new GI solution using "Hierarchical Radiance Cascades". From what I can see it seems to be similar to AMD GI 1.0 type of implementation (which CIG is using). They use screenspace probe grids to do the GI, but they use multiple cascades of radiance probes. The more detailed grid with lots of probes only captures information from nearby. The next level has quarter the number of probes but captures radiance from further away, and so on. Then they combine the results. That is my understanding. See the video link (it should start at the relevant part of the presentation). Apparently this gave improvements to GI quality and the cost scales nicely for them. Path Of Exile only needs to use screenspace information for GI, given the top down camera, but Alexander specifically said it would work with worldspace as well. Would something like this be feasible in SC ? I am an armchair graphics enjoyer and I don't know what the tradeoffs would be. I'm posting because it seemed interesting and so that CIG graphics devs are aware of it, incase they were not already.
