A community developer known as gebdag released a modification for Grand Theft Auto 2 called GTA2 RTX Remix, upgrading the 1999 top-down action game with full path tracing, dynamic day-night cycles, and 60 frames-per-second gameplay. The project bridges the aging engine to Nvidia’s RTX Remix platform by utilizing a custom translation layer.
Custom Translation Layer Bridges DirectDraw to Direct3D 9
Grand Theft Auto 2 originally relied on DirectDraw and early versions of Direct3D, interfaces that are incompatible with Nvidia’s RTX Remix platform, which requires Direct3D 9. To overcome this limitation, the developer programmed a custom rendering layer consisting of two distinct dynamic-link libraries, gta2dx9.dll and gta2dx9_vid.dll. These files act as a real-time translator, converting the game’s legacy graphical instructions into a modern interface that RTX Remix can process.
Path Tracing and Dynamic Lighting Transform Anywhere City
The integration of path tracing alters the visual presentation of Anywhere City. The modification introduces ray-traced reflections, soft shadows, and a continuous day-night cycle featuring sunrises and moonsets. Neon signs, explosions, and burning vehicle wrecks function as dynamic light sources that cast realistic illumination onto the surrounding asphalt and buildings. Players can adjust lighting parameters directly during gameplay by pressing the F4 key to open an integrated menu.
Widescreen Support and Performance Enhancements
Beyond lighting upgrades, the mod addresses several technical constraints of the original 1999 release. It replaces the default 4:3 aspect ratio with full 16:9 widescreen support and eliminates the pop-in artifacts of vehicles and pedestrians at the edges of the screen. Frame generation technology boosts visual fluidity to 60 frames per second.
The project is hosted as an open-source release on GitHub. Running the modification requires a 64-bit Windows 10 or Windows 11 operating system, the RTX Remix runtime files, and a copy of the base game. The author optimized the package specifically for version 9.6, a build released as a free download by Rockstar Games in 2004.
