The Mod

According to Rock Paper Shotgun, modder ChunkLeChuck has released DLSS IV, a mod that adds Nvidia DLSS, DLAA, and AMD FSR 3 to Grand Theft Auto IV. The report notes it is a lighter, quicker fix compared to Warcaco's RTX Remix mod, which previously added DLSS alongside high-resolution textures and path tracing.

RPS says the mod is compatible with HDR. DLAA offers anti-aliasing without upscaling, so it won't boost performance the way DLSS or FSR can, but the outlet notes that anyone modding GTA IV in 2026 likely has a PC that can already run it.

Rockstar Context

RPS points out that Rockstar recently updated its modding guidelines ahead of GTA 6, but those guidelines do not mention upscaling mods like DLSS IV. The outlet also reports that Rockstar allegedly considered a GTA IV remaster as recently as 2022, but reportedly shelved it after the negative reception to Grand Theft Auto: The Trilogy - The Definitive Edition.

These remaster claims remain unverified allegations from RPS, not confirmed facts. What is confirmed is that the DLSS IV mod exists and is now giving Liberty City's jagged edges a modern polish.
