Screen Space Directional Occlusion (SSDO) or Dynamic GI

I think that you are confusing the color bleeding that cryengine uses since version 3.7 for its directional oclusion that prevents it from shadowing bright parts of the scene , that is not global ilumination , gi is lightning bouncing from a surface to another and not stoping the first time it hits something .
