Deferred shading first stores opaque surface attributes in a G-buffer, then lights those attributes; extra storage and material representation become architectural concerns. Transparency commonly needs a separate path, and multisample antialiasing (MSAA) requires additional care. [1][3]\n\nForward+ retains forward material shading but constructs spatial light lists, often using compute-generated screen tiles. Fragments then evaluate candidate lights from their tile. AMD's sample provides an original implementation of this division of work.
