After a visit to Infinity Ward's R&D Centre in Poland we have new intel on the COD Engine upgrades shipping in Modern Warfare 4. Newly-added ray-marched fog and smoke, overhauled weather systems, and a new material pipeline are the highlights. Plus we have a behind-the-scenes look at path tracing (unreleased to the public), in comparison to the shipped ray tracing mode and its rasterised settings.
