NVIDIA tools help enthusiasts improve graphics in their favorite games.
Recently, a modder with the nickname PPBWoodBoy introduced a demo version of an improved version of Quake 3 Arena. He added path tracing to the game.
The tools used were RTX Remix 1.2.4, as well as Quake3e, imgupscaler.ai, and Photopea.
The modder added modern PBR materials (with physically correct rendering) to Quake 3 Arena, which interacts with the ray tracing, and preserved the original gameplay.
PPBWoodBoy distributes the project via ModDB and GitHub, repository "q3-rtx-demoPublic". The modification is intended for single player games.
