18 years later, GTA 4 got rid of jagged edges – new mod adds DLSS, DLAA and FSR to the game

Modder ChunkLeChuck has released DLSS IV on Nexus Mods for Grand Theft Auto IV.

The mod adds DLSS, DLAA, and FSR support to the 2008 game. Its main goal is to replace the original infamous anti-aliasing, which left visible jagged edges and shimmering on objects throughout the game.

The release lines up with updated rules for modders that Rockstar revised ahead of GTA 6. The new guidelines ban several types of modifications:

• unofficial story missions and expansions to the main narrative

• unauthorized ports, including a homemade PC version of GTA 6

• mods that combine maps from different entries in the series

Adding modern anti-aliasing and upscaling tech to older entries in the series doesn't fall under these restrictions. ChunkLeChuck work doesn't break any of the limits Rockstar has set.

DLSS IV isn't the first attempt to bring Nvidia or AMD tech into Grand Theft Auto IV. Modder Warcaco previously released a mod built on RTX Remix, where DLSS worked alongside a larger package of high-resolution textures and path tracing.

DLSS IV, though, offers a much lighter and faster fix for anyone who just wants to clean up the anti-aliasing in the base game without a full graphical overhaul.

The mod supports three technologies, each working a bit differently:

• DLSS – Nvidia machine-learned upscaler, available only to owners of GeForce RTX graphics cards

• DLAA – the anti-aliasing component of DLSS, which works without upscaling and outputs the image at native resolution

• FSR – AMD equivalent, with the mod apparently using FSR 3

FSR 3 doesn't deliver quite the same sharpness as Nvidia solution, but it works on any functional graphics card regardless of manufacturer. All three options noticeably smooth out edges on objects across the streets of Liberty City and support HDR.

DLAA doesn't lower the internal rendering resolution, so it doesn't provide the same performance boost as DLSS or FSR. That said, this likely won't be an issue for a game from 2008 – even a budget card like the RTX 3060 handles Grand Theft Auto IV without breaking a sweat.

The game has never gotten an official re-release. Rumor has it that Rockstar considered a full remaster of Grand Theft Auto IV with updated graphics back in 2022, but scrapped the idea after the rocky launch of Grand Theft Auto: The Trilogy – The Definitive Edition.
