Visibility Buffer and Deferred Rendering in DOOM: The Dark Ages

In this talk, we’ll present the new geometry rendering pipeline developed for idTech 8. Instead of rendering geometry in multiple passes and relying on a standard Forward+ opaque lighting evaluation using pixel shader we’ll show our journey towards using a triangle visibility buffer and a fully compute-based rendering approach. We’ll detail and compare different shading-dispatch strategies and share important performance considerations and guidelines we’ve discovered. In addition, we show how we combined this approach with an optimized tiled deferred lighting algorithm that’s also capable of performing compute-based software VRS These rendering techniques were shipped in DOOM: The Dark Ages (DtDA), developed by id Software and released in May 2025 on Xbox Series X|S, PlayStation 5 and PC to critical acclaim.
