A project called GTA2 RTX Upgraded uses Claude Code alongside Nvidia RTX Remix to give Grand Theft Auto 2 upgraded materials, path-traced lighting and real-time reflections. An XDA Developers writer says the visual changes are especially apparent at night, but the source does not provide independent performance testing or details about the project’s development process.
A project called GTA2 RTX Upgraded has expanded an earlier Nvidia RTX Remix treatment of Grand Theft Auto 2 with Claude Code-assisted changes to materials, lighting and rendering. An XDA Developers writer who tried it reports that the mod adds path-traced lighting and reflections, giving the 1999-era top-down game a substantially different look on compatible modern PC hardware.
The project builds on gta2-rtx-remix, an earlier effort created by GitHub user gebdag. The newer version, identified as GTA2 RTX Upgraded, is attributed to user kirrm3la, who used Claude Code to extend the visual changes. According to the XDA report, the updated rendering includes physically based materials, path-traced lighting and reflections that respond to the game environment.
The biggest visible changes in the writer’s account are to cars and nighttime scenes. Vehicle paint and glass respond to light, while reflections shift as cars move. The report also describes police and ambulance lights spilling onto nearby vehicles and the player character, and headlights illuminating people and buildings. These are the writer’s observations from trying the project, rather than results from a published technical benchmark.
The report says the installation involves placing the original open-source RTX Remix files and the upgraded project files in the GTA 2 installation directory, then launching the game executable. It describes the process as straightforward, while noting that obtaining the game may be the harder step because Rockstar has delisted it from its storefront. The source does not specify supported GPU models, frame rates across hardware, or a full compatibility list.
GTA 2 gets a new look with RTX Remix and Claude Code
GTA2 RTX Upgraded adds path-traced lighting, reflections and updated materials to the 1999 game. An XDA Developers writer reports the biggest changes in cars and nighttime scenes.
What the upgrade changes
The community project extends an earlier RTX Remix treatment of GTA 2.
More responsive surfaces
Vehicle paint and glass respond to light, with reflections shifting as cars move.
A different night scene
Path-traced lighting makes emergency lights spill onto nearby objects and headlights illuminate people and buildings.
How the project developed
The newer work builds on an existing RTX Remix effort.
GitHub user gebdag created the initial treatment of GTA 2.
User kirrm3la extended the project with updated materials, lighting and rendering.
What players should know
The report describes one writer’s experience, not a broad technical evaluation.
- Installation uses the RTX Remix and upgraded project files in the GTA 2 directory.
- The writer found setup straightforward and gameplay smooth on their system.
- Supported graphics cards and performance across different PCs.
- Claude Code’s specific contributions or the project’s known limitations.
Before trying the mod
Check current project instructions and your setup.
- Consult the project’s GitHub instructions for current files and requirements.
- Confirm your GTA 2 copy and PC can run the setup.
- Rockstar has delisted the game from its storefront; the report does not establish other authorized purchase options.
A New Rendering Life for GTA 2
The project shows how RTX Remix can be used to revisit an older game’s presentation without replacing its top-down design. Rather than remaking GTA 2 as a new game, the mod changes how its existing world responds to light, with cars, streets and emergency lights gaining effects that were not part of the original rendering.
It also offers a small example of AI coding tools entering game modding. The source attributes the upgraded work to Claude Code, but does not detail which parts of development involved the tool or how much work was done by the project’s creator. The result is of interest to players curious about preservation and visual modding, while the available account is not enough to establish how easily it runs across different PCs.

From Top-Down Crime to RTX Remix
Grand Theft Auto 2 was released in 1999 and continued the series’ top-down format before Grand Theft Auto III moved the mainline games into 3D. The XDA report describes it as the last mainline entry to use that perspective; later, Rockstar also returned to a top-down approach with titles such as Chinatown Wars.
Nvidia’s RTX Remix is software for modifying the rendering of older games, including by adding ray-tracing features. The GTA 2 project had already received an earlier RTX Remix treatment from gebdag before kirrm3la’s Claude Code-assisted upgrade. The new work is presented as an extension of that project, not an official Rockstar release or a new edition of GTA 2.
“The result, then, isn’t “GTA 2 with prettier lighting,” however.”
— XDA Developers writer Samarveer
Hardware Support and Mod Details
The source does not provide independent technical testing, a list of supported graphics cards, or performance measurements across different systems. It mentions frame generation as an available RTX Remix option and describes smooth gameplay in the writer’s experience, but gives no benchmark methodology or hardware specifications. Those observations should not be taken as a performance guarantee.
It is also unclear how Claude Code was used during development, whether the project has known bugs or limitations, and how its files are maintained. The source directs readers to project files but does not establish the legal status or current availability of every file needed to install the game. Rockstar’s storefront delisting is reported, but the article does not explain whether the game can be obtained through other authorized channels.
Check the Project Before Installing
Players interested in trying the visual upgrade will need to consult the project’s GitHub instructions for current files and installation requirements, and check that their GTA 2 copy and PC can run the setup. The source does not announce a release date for further updates or describe planned features, so the project’s next development milestone is unknown.
Further reporting or project documentation would be needed to confirm compatibility, performance on a range of hardware, and the extent of Claude Code’s role. Until then, the clearest account available is the XDA writer’s hands-on description of the changes and installation process.
