Eighteen years after its initial release, Grand Theft Auto IV has gained support for NVIDIA's DLSS and AMD's FSR technologies through a new mod. The "DLSS IV" mod, created by ChunkLeChuck, allows players to integrate DLSS, DLAA, and FSR into the base game, offering a modern visual enhancement.
This mod arrives amid updated modding guidelines from Rockstar Games, which caution against creating unofficial story missions or PC ports for upcoming titles like GTA 6. However, the guidelines do not address enhancements to older games like Grand Theft Auto IV. While a previous mod by Warcaco also integrated DLSS as part of a broader suite of graphical improvements, DLSS IV aims to provide a more streamlined solution focused solely on upscaling and anti-aliasing.
DLSS, developed by NVIDIA, is a proprietary AI-powered upscaling technology for GeForce RTX graphics cards. DLAA serves as the anti-aliasing component of DLSS without the upscaling function. The mod's implementation of FSR, AMD's open-source upscaling technology, appears to be FSR 3, which, while potentially less sharp than NVIDIA's technology, offers broader compatibility across various GPU manufacturers.
These upscaling options can help to refine the visual fidelity of Liberty City's environments. DLAA, by not upscaling the image, will not provide the same performance boost as DLSS or FSR, though the mod's creator suggests that players interested in modding GTA IV in 2026 likely possess hardware capable of running the game smoothly regardless. The mod is also noted to be compatible with HDR.
This development follows reports that Rockstar Games considered a modern remaster of Grand Theft Auto IV as recently as 2022. However, this project was reportedly shelved following the largely unenthusiastic reception of Grand Theft Auto: The Trilogy - The Definitive Edition, which faced criticism for its technical issues and overall quality.
