GTA 6 engine: RAGE, from 2006's Table Tennis to Vice City

Grand Theft Auto VI runs on RAGE, the Rockstar Advanced Game Engine that Rockstar Games has used for its own releases since 2006. Digital Foundry links the game’s footage to that engine in its August 28 and October 16, 2026 breakdowns, ahead of the November 19, 2026 launch on PS5 and Xbox Series X|S. As of October 21, 2026, neither Rockstar nor Take-Two has put a name or version number on the build GTA 6 uses.

An engine born out of an EA deal

Rockstar built RAGE because Electronic Arts bought Criterion, the company behind RenderWare, the middleware that ran GTA III, Vice City and San Andreas. Co-founder Jamie King told Time Extension in 2021 how Sam Houser reacted: “F***ing EA’s just bought Renderware, we need to make our own engine, sort it out!” King’s team then “brought people from Rockstar Vienna and Rockstar North to San Diego and we created RAGE.”

The first game out of it was a sports title. Rockstar Games Presents Table Tennis, released on Xbox 360 in 2006, grew out of a Rockstar San Diego tech demo, “a game for us to show off or prove our game engine from a physics perspective,” King said. Wikipedia credits the engine today to the RAGE Technology Group, a division of that studio.

GTA V on PC	2025	ray-traced global illumination, which Digital Foundry links to GTA 6 (Eurogamer)
GTA 6	2026	more than 600,000 animations per Rockstar, driving rebuilt from scratch per Rob Nelson

Euphoria and the way bodies fall

On February 27, 2007, MCV reported that Rockstar had licensed euphoria from Oxford-based NaturalMotion for its next-generation games. Instead of replaying canned animation, euphoria works out how a body reacts in real time. NaturalMotion CEO Torsten Reil put it this way: “We now have the processing power to simulate humans, and the possibilities for games are endless.” GTA IV, released April 29, 2008, was the first Rockstar game to use it.

Ten years on, Rockstar North director of technology Phil Hooker explained its role in Red Dead Redemption 2 to VG247: “We use Euphoria specifically to enhance the physics-based reactions of both humans and animals.” He called it “just a part of how we simulate and animate characters,” next to an animation system the studio had “radically overhauled.” Rockstar has not said whether GTA 6 still uses euphoria.

Now head of development, Hooker brought up the engine again in Bloomberg’s October 14, 2026 feature: “the engine, the tools and the team we’ve built during this project will allow us to do things more quickly” on Rockstar’s next game.

What Digital Foundry sees in GTA 6

On March 15, 2025, Digital Foundry broke down the GTA 5 PC upgrade and its ray-traced global illumination, which calculates how light bounces off every surface. It works from any light, car headlights included, at per-pixel detail. The outlet’s read: “this may well be tech for the upcoming Rockstar release backported to GTA 5 on PC,” since GTA 6’s first trailer shows lighting “with a similar level of fidelity.”

The judder goes back much further. On August 28, 2026, Digital Foundry spotted camera and animation stutter in the Extended Look even with a steady frame rate, and blamed RAGE. On October 16, 2026, it called this “an unfortunate feature of past RAGE engine titles since Grand Theft Auto 4,” then found the launch trailer free of it, “including in slow pans.” Its caveat: Rockstar could have shot the video in a way that hides the problem. The rendering numbers are in our Extended Look breakdown, the settings in the performance mode guide.

The rebuilt-engine theory

Former Rockstar audio engineer Rob Carr told Kiwi Talks, as GamingBolt reported on April 3, 2026, that the studio has “probably rebuilt the entirety of the Rage Engine.” He bases that on how long development has run, and he opened with a warning: “I know nothing about it.” As of October 21, 2026, no official or press source backs him up.
