Grand Theft Auto VI (Prep): Speculative settings.xml for RAGE Engine 9

RAGE 9 moves away from “baked” lighting entirely, favoring a hybrid Ray-Traced Global Illumination (RTGI) and Physically Based Rendering (PBR) pipeline. The configuration below assumes the PC version will follow the 2025 RAGE patterns.

Optimized Speculative Configuration Table

Parameter	Expected Value	Technical Purpose
DeepLearningSuperRes	1	Enables AI upscaling (DLSS 4/FSR 4) to handle RTGI overhead.
RayTracedGlobalIllum	1	Enables the per-pixel light bounce seen in the Leonida trailers.
FluidSimQuality	3	The Water Fix. Controls the real-time wave mass and drag simulation.
PedestrianLogicRate	2	Balances the “Florida Man” AI routines to save CPU cycles.
SoftBodyDeformation	true	Enables the procedural vehicle damage and chassis twisting.

HowTo: Preparing Your Rig for the RAGE 9 Leap

Follow these GameEngineer.net technical steps to ensure your hardware is ready for the Leonida launch:

1. The CPU Bottleneck: Unlike GTA V, the RAGE 9 engine is heavily limited by Single-Core IPC and L3 Cache. In 2026, chips with 3D V-Cache (e.g., Ryzen 9800X3D) are essential for handling the Euphoria 2.0 central nervous system simulation for every NPC in dense crowds.
2. VRAM Management (PBR Pipeline): Because RAGE 9 uses Physically Based Rendering, every material has density, roughness, and metallic maps. This will likely push VRAM requirements beyond 12GB for 1440p High settings. If you have an 8GB card, prepare to set TextureQuality to “Medium” regardless of your GPU power.
3. Real-Time Hydro-Physics: Leonida (Florida) is water-centric. The engine now calculates waves as physical objects with mass. If your frame rate drops near the coast, look for a speculative Water_FluidSim setting in the XML—lowering this will likely revert the water to a RDR2-style “Deformable Plane” to save GPU cycles.
4. Ray-Traced Global Illumination: The 2025 GTA V PC update proved that Rockstar’s RTGI is extremely scalable. Even on mid-range cards (RTX 4060/5060), you can likely keep RTGI on “Low” or “Medium” to get that essential “neon glow” on wet Vice City streets without tanking your FPS.
5. SSD Mandatory: RAGE 9 is built around high-speed NVMe asset streaming. Mechanical HDDs will cause massive “Asset Pop-in” and likely “Fall-through-the-map” errors during high-speed driving.

Technical Explanation: From Raster to Simulation

In previous RAGE iterations (GTA V), damage was a pre-baked “dent” animation. In RAGE 9, the engine utilizes Soft-Body Physics calculations.

The engine treats vehicles as a collection of interconnected “nodes” and “beams.” When an impact occurs, the engine calculates the force vector and deforms the structural skeleton in real-time. This is why the Deformation_SoftBodyEnabled flag is so critical—it moves the physics calculation from a simple script to a real-time math problem. On consoles, this is what limits the game to 30 FPS; on PC, having a high-thread-count CPU will be the only way to unlock 60+ FPS while maintaining these procedural damage patterns.
