RAGE 9 Engine: What GTA 6 Actually Runs On

RAGE 9 is not an official name. Grand Theft Auto VI runs on Rockstar’s in-house engine, RAGE - the Rockstar Advanced Game Engine - but Rockstar has never called the GTA 6 version “RAGE 9” or given it any version number at all. The “9” is fan shorthand that spread across YouTube, Threads and gaming blogs until it read like fact.

That matters because a lot of what gets written about RAGE 9 comes from the same place: patents that aren’t tied to GTA 6, leaks Rockstar never confirmed and percentages nobody can source. This is what’s on the record about GTA 6’s engine, what’s rumour, and where AI really fits - which, according to Take-Two, is nowhere in the game itself.

Is RAGE 9 GTA 6’s Official Engine?

No. RAGE is real and Rockstar has used it for years, but the version numbering is a community invention. No Rockstar or Take-Two statement, credit or job listing I could find uses “RAGE 9”.

Rockstar doesn’t publish engine details the way Epic does with Unreal. What’s known about GTA 6’s tech comes from three places: what Rockstar has shown, what analysts have measured from that footage, and patents filed by Take-Two. Everything else is guesswork.

Even the question of how much the engine changed is open. Former Rockstar audio designer Rob Carr said on the Kiwi Talkz podcast that the studio “probably rebuilt the entirety of the Rage Engine” - but he left Rockstar in 2016, and games.gg reports he framed it as his own speculation rather than inside knowledge.

What the Footage Actually Shows

The trailers are the best evidence there is, because they’re the engine running - Rockstar said Trailer 2 was captured in-game on a PlayStation 5. Digital Foundry’s frame analysis, summarised by RockstarINTEL, put it at roughly 1440p upscaled to 4K at 30 frames per second, with ray-traced global illumination running through almost every shot. Alex Battaglia’s point was that the lighting can’t simply be switched off for speed: “You can’t get rid of Ray-tracing Global Illumination, it’s inherent to the way the game works.” The full breakdown is in our Trailer 2 analysis.

Frame rate is the one hard number, and it comes from Rockstar. Kotaku reported on 27 August 2026 that Rob Nelson, head of development at Rockstar North, told YouTuber Davy Jones the consoles are running the game at 30 frames per second in development, with no commitment yet on a 60fps mode. The PlayStation Store listing marks the game as PS5 Pro Enhanced, but neither Sony nor Rockstar has said what the Pro version does differently. If you’re choosing hardware, the console buying guide goes through all of it.

The older idea that AI upscaling would unlock 60fps on consoles isn’t supported by anything Rockstar has said since.

What the Patents Say - and Don’t

Two Take-Two patents get quoted in almost every RAGE 9 article. They’re real documents. Neither one mentions GTA 6.

Runtime retargeting

US20250095261A1, “System and method for runtime retargeting”, is a Take-Two application filed in September 2024 and published in March 2025. It covers adapting character animation to the world in real time - a character’s feet meeting different steps of a staircase, for example - and discusses inverse kinematics. It is an application, not a granted patent, and nothing ties it to a specific game.

Procedural interiors

US 10,987,587 B2, “System and method for game object and environment generation”, was filed in December 2017 and granted in April 2021. It describes tagging interchangeable parts - its examples include “old,” “worn_down,” “rusty,” “cheap” - so an engine can build many different interiors from a small set of objects. In the patent’s words:

the disclosed systems are used to procedurally generate building interiors, which allows the generation of large number of different interiors from a relatively small set of interchangeable part objects

That’s a real and interesting system. What it doesn’t contain is the famous “70% of buildings are enterable” figure. That number traces to fan analysis of patents, repeated in a GTA BOOM report in January 2024. Rockstar has never given a percentage, and the patent has no persistence system for saving furniture you move around.

Water, Hurricanes and the Rest

Hurricanes and water

Hurricane and flood claims come from social media posts picked up by outlets like Notebookcheck in August 2025. Rockstar hasn’t confirmed them. The specific technique often attached to them - FFT ocean simulation - doesn’t appear in that coverage, in the patents or in anything Rockstar has said.

NPC routines

The NPC claims have the same shape. A Brazilian retailer, KaBuM!, described NPCs with “their own routines based on advanced AI” in a product listing, reported by Insider Gaming in June 2026. Insider Gaming noted no other retailer carried that text and that it could change. Rockstar hasn’t commented. “Advanced AI” in a store blurb almost certainly means conventional game AI - the behaviour systems every open world has - not a chatbot living inside every pedestrian. That last part is my read, not something the listing says.

Does GTA 6 Use Generative AI?

No, according to the head of the company that owns Rockstar. Speaking to GamesIndustry.biz around Take-Two’s results in February 2026, CEO Strauss Zelnick said, as reported by GameSpot:

Specifically with regards to GTA 6, Generative AI has zero part in what Rockstar Games is building

He went further on how the world is made:

Their worlds are handcrafted. That’s what differentiates them. They’re built from the ground up, building by building, street by street, neighborhood by neighborhood. They’re not procedurally generated, they shouldn’t be.

There’s a nuance worth keeping. Zelnick isn’t anti-AI across Take-Two. In the same remarks he said the company has “hundreds of pilots and implementations across our company, including within our studios,” and that its products have always used machine learning. The line he drew is between tools used around development and generated content inside GTA 6.

He’d made the creative argument months earlier, at CNBC’s Technology Executive Council in October 2025, per PCGamesN: “There is no creativity that can exist by definition in any AI model, because it is data-driven.”

Genie 3 and Project Genie

Genie 3

Genie 3 is the other half of this article’s original title, and it’s a very different kind of thing. Google DeepMind announced Genie 3 on 5 August 2025 as a world model: type a prompt and it generates an environment you can move through in real time. There’s no hand-built map underneath, no physics code - the model predicts each frame as you go.

The limits are the story. DeepMind’s own announcement puts it at 720p and 24 frames per second, with worlds staying “largely consistent for several minutes” and a few minutes of continuous interaction rather than hours. It lists text rendering and accurate real-world locations among its weaknesses.

Project Genie

In January 2026 Google opened Project Genie, a prototype built on Genie 3, to its top-tier AI subscribers in the US, with generation capped at 60 seconds. Investors reacted anyway: Take-Two’s stock had fallen more than 11% from its opening at one point on 30 January, per Notebookcheck. Zelnick’s “zero part” comments came days later.

Handcrafted vs Generated

Put GTA 6 and Genie 3 side by side and the gap isn’t close. One is a state with cities, swamps and keys that has to hold together for an entire playthrough. The other holds a scene together for minutes and can’t reliably draw a street sign.

I think the market panic in January mixed up two questions. Can AI generate something that looks like a game? A little, briefly. Can it generate a place worth living in for years - with consistent geography, a story, and a city that remembers what you did? Nothing Google has shown gets near that yet.

A useful tell while leaks are everywhere: generated video still struggles with the exact things DeepMind lists as weaknesses. Signs whose text shifts when the camera moves, or buildings that don’t stay put, point to AI footage rather than real GTA 6.

None of that means AI stays out of games. It’s arriving in tools and graphics - Nvidia’s Jensen Huang described DLSS 5 in March 2026 as “blending handcrafted rendering with generative AI” - and Take-Two itself says it’s piloting AI widely. But if Zelnick’s word holds, everything you’ll walk through in Leonida was built by people, on an engine Rockstar has never bothered to number.
