Found that one in GAF.
To resume do you remember the differences between the original UE4 PC and the PS4 version? The lack of Sparse Voxel Octree Global Illumination (SVO-GI)? So Sony showed alternatives to how to do that on PS4.
Insted to do the SVO-GI using heavy CPU processing they combined CPU + GCN (GPU) to create SVC-GI with a similar result.
