A GZDOOM community mod called "DOOM II: Ray Traced" has done the unthinkable—added path-traced lighting, shadows, and reflections to DOOM II. The mod uses high-resolution voxel models and other game assets from the Voxel DOOM Project, which replaces the game's 2D sprites as fully-fledged 3D models. Pretty much all of the game's textures also see an improvement. Where "DOOM II: Ray Traced" comes to light is its path-traced lighting, which uses ray tracing hardware of modern GPUs—nothing is pre-baked. The mod also supports NVIDIA DLSS 3 Frame Generation and AMD FSR 3.0 Frame Generation, to help step up performance. A gameplay video sees a GeForce RTX 4080 break a sweat rendering it at 4K. And to think the original DOOM II could run on an 80386—a processor simpler than a single NVIDIA CUDA core.
