11 Overview

3-The Rockstar Advanced Game Engine (RAGE) is the proprietary game engine developed by Rockstar Games that powers Grand Theft Auto VI. The version used for GTA VI is informally referred to as "RAGE 9" by the community, representing the latest major revision of the engine. This iteration introduces significant advances in lighting, character rendering, environmental detail, and world simulation, designed to take full advantage of PlayStation 5, Xbox Series X|S, and high-end PC hardware.

3+Grand Theft Auto VI runs on the Rockstar Advanced Game Engine (RAGE), Rockstar’s proprietary game engine. Rockstar has not publicly assigned a version number to the engine iteration used for Grand Theft Auto VI; any version label such as "RAGE 9" is an unofficial community convention.

5-RAGE has been Rockstar's engine of choice since 2008, powering every major release across the studio's open-world catalog. Each new project has brought significant upgrades to the engine, and GTA VI represents the most ambitious leap yet.

5+Rockstar confirmed that footage in Trailer 2 was "Captured on PS5," meaning the visual quality on display is the actual output of the engine running on a PlayStation 5 console.

7+Visible Engine Capabilities

9-Ray-Traced Global Illumination

9+The two official Rockstar Games trailers and the official screenshots published alongside Trailer 2 show the following behaviors. Specific implementation details have not been published by Rockstar; the wiki documents only what is visible on-screen.

11-GTA VI uses a ray-traced global illumination (RTGI) system for its lighting. of the trailers confirmed that the game employs ray tracing for both direct and indirect lighting, producing natural light bounce, soft shadows, and accurate ambient occlusion throughout the game world. This system simulates how light rays bounce off surfaces, creating realistic shadows, reflections, and atmospheric lighting effects.

11+Lighting and Reflections

1212

13-The RTGI system is most visible in scenes featuring varied lighting conditions: sunlight filtering through trees, neon signs reflecting off wet pavement at night, and interior spaces lit by a combination of natural and artificial light sources. Ray-traced reflections are especially prominent on transparent objects such as sunglasses, mirrors, and car windscreens, producing accurate reflections of the surrounding environment.

13+Trailer 1 and Trailer 2 show ray-traced reflections on glass surfaces, car bodywork, wet pavement, and water. Indoor and outdoor scenes show physically plausible light bounce, ambient occlusion, and soft shadows. Vehicle mirrors show real-time reflections of the surrounding environment.

15-Strand-Based Hair Rendering

15+Character Rendering

1616

17-One of the most technically impressive features in GTA VI is its strand-based hair rendering system. Rather than using textured polygons to approximate hair (as in previous GTA titles), the engine renders individual hair strands that respond to physics simulation. Hair reacts to wind, character movement, and gravity, producing natural-looking motion.

17+Trailer footage shows character hair responding to wind and movement, with individual strands visible at close range. Skin, clothing fabric, and accessories display per-material lighting responses. The two protagonists, Jason and Lucia, are the most visible examples; supporting characters and ambient NPCs display similar treatment in trailer scenes.

1818

19-scenes in the trailers where character hair flies up naturally during movement, confirming the presence of a strand-based hair system. Individual hair strands also cast high-quality shadows on character faces and bodies, with no visible shimmering artifacts. This technology is applied to both protagonists, Jason and Lucia, as well as to significant NPCs. The hair system works in conjunction with the game's dynamic hair growth mechanic, where hair and facial hair lengthen over time.

19+Environment and Weather

21-Procedural Generation

21+Trailer footage shows dynamic weather including rain with surface puddles and reflective wet textures. Volumetric clouds, atmospheric haze in the Grassrivers region, and day-to-night transitions are all visible. Vegetation reacts to wind in trailer scenes, with grass, leaves, and loose foliage moving independently.

2222

23-A Rockstar Games engineer confirmed through a professional profile that GTA VI uses procedural generation for objects and game environments. This technology dynamically creates and places environmental objects, reducing the repetitive patterns that can occur in hand-placed open worlds. The system covers the placement of smaller elements such as vegetation, debris, vehicles, and architectural details.

23+Water and Vehicles

2424

25-The procedural generation system works alongside hand-crafted world design rather than replacing it. Major landmarks, buildings, and geographic features are manually designed by Rockstar's world-building team, while the procedural system fills in environmental detail to ensure that no two areas look artificially identical. This hybrid approach allows the massive scale of Leonida's open world to maintain visual variety across every neighborhood and region.

25+Water surfaces in trailer footage show wave behavior that varies by location (open ocean, river, lake, marina). Vehicle interiors display working dashboard instruments. Damage in driving scenes is visible at the panel level rather than as a flat texture swap.

27-Environmental Detail

27+What Rockstar Has Not Detailed

2828

29-Vegetation in GTA VI is noticeably denser and more detailed than in any previous Rockstar title. Trailer analysis reveals individually rendered grass blades that respond to wind and character interaction, trees with detailed leaf systems, and dense undergrowth in natural areas like Mount Kalaga and the Grassrivers. The subtropical climate of Leonida provides a variety of biomes, from manicured urban parks to wild mangrove swamps, each with distinct vegetation profiles.

29+Rockstar has not published a technical breakdown of the engine used for Grand Theft Auto VI. Information about engine systems, patent filings, or claimed render features that does not appear in an official Rockstar publication or in trailer footage is excluded from this article.

31-Water Rendering

31+Engine History

3232

33-Water simulation in GTA VI represents a major upgrade. The engine produces high-quality mesh deformation for waves and ripples, translucent water surfaces with visible underwater terrain, and caustic light effects where sunlight refracts through moving water. Ocean waves, river currents, and lake surfaces each behave differently. This reflects the variety of water bodies across Leonida.

33+RAGE has powered Rockstar’s major open-world releases since 2008. Each major Rockstar release has brought visible upgrades to the engine. Grand Theft Auto VI represents the latest iteration, optimized for current-generation console hardware.

35-The water rendering system is particularly important given Leonida's geography. The state is surrounded by ocean on three sides, contains a major freshwater lake (Lake Leonida), extensive swamplands, and a chain of tropical islands. Water is encountered constantly during gameplay, making its visual quality and physical behavior critical to the overall experience.

39-GTA VI's shadow rendering system casts shadows from both near and distant objects, with multiple light sources adding to shadow calculation simultaneously. Global light (the sun) and local light sources (street lamps, neon signs, vehicle headlights) both generate shadows, creating layered, realistic shadow interactions throughout the game world.
