GTA 4 Mod Adds DLSS, DLAA and FSR Support

A new mod adds DLSS, DLAA and FSR support to Grand Theft Auto IV on PC. Called DLSS IV, ChunkLeChuck’s project is designed to smooth out the jagged edges and visual shimmering of the game released in 2008. Rock Paper Shotgun presented it as a more direct modernization of Liberty City’s original image.

The mod does not attempt to replace textures, rebuild the lighting or transform GTA 4’s entire presentation. Its focus is on Nvidia and AMD image reconstruction and anti-aliasing technologies. That makes it an option for players who want to preserve the base game’s look while improving how its edges are displayed.

What the mod adds to GTA 4

DLSS is Nvidia’s machine-learning image reconstruction technology. In the implementation described by the source, it is available for GeForce RTX graphics cards and can use a lower internal resolution to produce the final image. This approach can also reduce the rendering workload, although Rock Paper Shotgun does not provide performance tests for the mod.

DLAA uses the anti-aliasing component of DLSS without applying image upscaling. The option prioritizes edge treatment when a computer can already render the game at the desired resolution. Because it does not use upscaling, it does not offer the same potential performance benefit associated with DLSS or FSR.

The AMD alternative apparently used by the mod is FSR 3, according to Rock Paper Shotgun. The outlet considers it less sharp than Nvidia’s technology but highlights its broader compatibility. The source says the feature should work on functional GPUs from different manufacturers instead of being limited to GeForce RTX cards.

All three options are intended to reduce the jagged appearance and shimmering associated with GTA 4’s original anti-aliasing. The mod is also compatible with HDR, according to the report. The source does not, however, provide detailed comparisons between each mode, resolution or graphics setting.

How it differs from other projects

This is not the first attempt to bring modern image technology to GTA 4. Warcaco’s RTX Remix project previously added DLSS as part of a broader package that also included high-resolution textures and path tracing. DLSS IV takes a more limited approach and, according to Rock Paper Shotgun, appears to be a lighter, quicker and cleaner solution for players who only want to improve the base game’s image.

That distinction defines the likely audience for each mod. A package such as RTX Remix seeks to overhaul several visual elements at once, while DLSS IV concentrates on image reconstruction and anti-aliasing. For players who prefer to retain Liberty City’s original visual identity, the more restrained approach may be its main attraction.

The mod also arrives after a recent update to Rockstar’s modification guidelines, which the report mentions in connection with GTA 6. Rock Paper Shotgun notes that the rules address restrictions such as unofficial story missions and a potential unauthorized GTA 6 PC port. The source does not identify a specific ban on the graphics technologies added to GTA 4 by DLSS IV.

What changes for GTA 4 players

In practical terms, PC players now have three approaches to treating image edges without necessarily adopting a complete visual overhaul. GeForce RTX owners can consider DLSS or DLAA, while FSR extends the option to hardware from other manufacturers. The choice depends on whether the priority is sharpness, native-resolution rendering or a possible reduction in rendering load.

HDR compatibility adds another option for modern setups, but the report does not detail monitor requirements or recommended settings. It also provides no figures showing how many frames per second DLSS or FSR might add. The actual performance impact therefore remains dependent on testing not included in the source.

What remains unknown

Rock Paper Shotgun does not explain how the mod should be installed, where it will be maintained or which specific versions of GTA 4 are supported. Questions about conflicts with other mods, stability and future updates also remain open. Without cited benchmarks, it is not yet possible to compare the image quality and performance of DLSS, DLAA and FSR 3 objectively within the game.

The report also recalls allegations that Rockstar had considered a modern GTA 4 remaster as recently as 2022. According to those unconfirmed claims, the idea was dropped after the largely unenthusiastic reception to Grand Theft Auto: The Trilogy – The Definitive Edition. This does not confirm that a remaster was planned, but it helps explain why community projects continue to occupy the space of visually modernizing the game.

For now, the concrete development is that DLSS IV offers a focused graphics update for the PC version of GTA 4. The project combines current technology with Liberty City’s base appearance without attempting the extensive overhaul offered by other mods. The information about its features and the differences between them was published by Rock Paper Shotgun.
