The Rockstar Advanced Game Engine (RAGE) has been around since 2006. Several of Rockstar Games' most memorable open-world games, such as GTA IV and GTA V, are powered by it.
In recent years, Rockstar used the RAGE engine for 2018's Red Dead Redemption 2, making it rather unlikely that Rockstar would use a different engine for the next Grand Theft Auto game, GTA 6.
A reputable Rockstar source now claims that Rockstar has hugely ambitious plans for GTA VI's video game engine.
According to Matheusvictorbr, RAGE 9 will include multiple unique features, some of which will be exclusive to GTA 6, including massive improvements to how players and NPCs interact with each other and the world around them.
The same source says that RAGE 9 will also revolutionize environmental effects, including water physics and even how wind affects driving vehicles.
In addition, Rockstar is reportedly expecting RAGE 9 "to compete directly with Unreal Engine 5," with the RAGE engine already capable of supporting 16K textures as early as 2018. In comparison, Unreal Engine 4 maxes out at 8K resolution. Meanwhile, its latest iteration, Unreal Engine 5, can only support 12K resolution. We have been told that GTA 6 will benefit from the full force of the game engine's "revolutionary" mechanics.
