The unofficial RTX remaster of Grand Theft Auto IV is being improved not only by the developer xoxor4d.
DarkoRTX has introduced a set of HD textures that enhance the quality of surfaces and materials. The modder clarified that this is not just "upscaling:":
Many textures are supplemented with PBR maps and manually refined for more realistic RTX lighting. This is an evolving project, it is gradually expanding to cover the entire game world.
Most of the buildings, roads, and pavement surfaces have already been updated. The textures are created in 2K and 4K resolution: "depending on the situation — to maintain high quality with reasonable file sizes."
The mod "DarkoRTX proper GTA IV RTX Remix Texture Remaster" for Grand Theft Auto IV is distributed free of charge via Nexus Mods.
