For millions of gamers, the gritty, rain-slicked streets of Liberty City in Grand Theft Auto IV represent a high point in storytelling and open-world design. But let's be honest: released back in 2008, the game is starting to show its age. While fans hold their breath for an official remaster, a new project is emerging from the modding community that feels nothing short of miraculous. A creator known as xoxor4d is using the power of NVIDIA's RTX Remix tool to completely transform GTA IV, and the first results are breathtaking.
This isn't just a simple texture pack or a shader tweak. This ambitious mod aims to reforge the entire visual identity of the game, leveraging cutting-edge rendering technology to give Liberty City a look that rivals modern titles.
From 2008 to 2024: A Technological Leap
The original GTA IV was a technical marvel in its day, praised for its advanced physics and dense, living city. But by today's standards, its lighting can feel flat, its textures muddy, and its overall aesthetic dominated by a now-notorious "yellowish" tint.
The RTX Remix mod attacks these issues at their core. The headline feature is the implementation of real-time path tracing. For those unfamiliar with the term, this is the holy grail of lighting simulation. Instead of using pre-baked or approximated light sources, path tracing accurately models the physical behavior of light as it bounces around a scene. This means:
- Dramatic, realistic shadows: Every object casts soft, natural shadows based on the light sources.
- True-to-life global illumination: Light from a neon sign will realistically bleed onto the wet pavement and the sides of buildings, creating a vibrant, atmospheric glow.
- Precise reflections: Instead of screen-space approximations, reflections on car bodywork, puddles, and windows are physically accurate, showing objects and light sources that are even off-camera.
The result is a Liberty City that feels more tangible and immersive than ever before. The iconic skyline isn't just a backdrop; it becomes an integral part of the lighting environment.
More Than Just Lighting: A Complete Visual Overhaul
While the path tracing is the star of the show, xoxor4d's work extends further. The mod also includes significant upgrades to the game's textures. Buildings, roads, and vehicles are being treated to higher-resolution materials, which, when combined with the new lighting system, erase years of visual decay.
Imagine the chrome detailing on a speeding Turismo gleaming with accurate reflections, or the brickwork on an Algonquin apartment building having real depth and texture. This combination of cutting-edge lighting and enhanced assets is what pushes the project from a "graphics mod" into "remaster" territory.
See It to Believe It: The Mod in Motion
A description can only do so much justice to such a visual transformation. Fortunately, the modder has released a preview video that showcases the staggering difference this RTX Remix project makes.
In the middle of the action, the video demonstrates Niko Bellic both behind the wheel and on foot, giving us a perfect before-and-after look at Liberty City under the mod's influence. It’s one thing to hear about path tracing; it’s another to see the rain-soaked asphalt of Star Junction reflecting a kaleidoscope of neon, or the interior of a car accurately shaded by the world outside.

A Labor of Love Still in the Oven
Before you rush to update your copy of GTA IV, it's crucial to manage expectations. xoxor4d has been clear that this mod is very much still in development. The video is a proof-of-concept, a stunning glimpse into what's possible. As with any project of this scale, there is no confirmed release date yet.
The creator has stated that the mod will be free upon release, a testament to the passion-driven nature of the modding community. For now, fans will need to exercise a little of the patience that Niko Bellic so often preached. The good news is that the project is actively being worked on, and the progress so far suggests it will be well worth the wait.
This RTX Remix mod is more than just a fresh coat of paint; it's a fundamental re-imagining of a classic game's visual soul. It proves that with modern tools, the worlds we fell in love with years ago can be reborn, offering a new generation—and nostalgic veterans—a reason to get lost in the streets of Liberty City all over again.
