Technical Deep Dive: Ray-Traced Global Illumination, Strand Hair Physics & Crowd Density in RAGE
Editorial Summary & Verification Context

Third-party technical analyses from Digital Foundry and graphics researchers highlight major upgrades to Rockstar's proprietary RAGE engine for GTA VI, particularly in real-time global illumination, specular reflections, strand-based hair simulation, and NPC body variety.

Interior scenes—such as Lucia's prison interview and the Port Gellhorn motel room—exhibit bounce lighting and soft indirect shadows characteristic of hardware-accelerated Ray-Traced Global Illumination (RTGI).

Vehicle side-mirrors and wet asphalt along Ocean Drive display coherent ray-traced reflections of neon hotel signage.

Beachfront and nightclub sequences demonstrate unprecedented NPC density with distinct body morphs, cloth physics, and individual strand hair movement.
