Modder xoxor4d has released the first public build of the Path Tracing RTX Remix Mod for Grand Theft Auto 4, bringing real-time path-traced lighting to the 2008 open-world classic. The 1.0.0 package is compatible with the Fusion Fix mod, meaning players can layer the path tracing renderer on top of community fixes that address numerous technical issues left unpatched in the original game.
Players can download the build from the GTA 4 RTX Remix Mod 1.0.0 on GitHub. The release includes straightforward installation instructions and a bundled helper script for CPU affinity. If you see heavy stuttering, launch the game with the provided LaunchWithProcessorAffinity_2Cores_GTA4.bat to bind two cores to GTA4 and leave the rest for Remix. The modder also recommends starting with a view distance of 50 and a quality setting of 30 in the game’s graphics options, then tuning from there to avoid CPU bottlenecks.
Path tracing is demanding, so expect a need for a high-end GPU; the mod appears to support DLSS 4 with Multi-Frame Gen for performance gains. Because this is the first public release, users may encounter bugs and visual glitches as the mod matures. For readers who want to see how the mod looks in action, Console PC Gaming previously ran a gallery of screenshots from earlier work-in-progress builds in Grand Theft Auto IV RTX Remix Path Tracing Mod Shows Stunning Screenshots.
Community testers and curious players will find the release mirrors a wider push this year to retrofit classic shooters and older PC titles with RTX Remix path tracing, joining recent mods for other franchises.
