Portal RTX came out last November as a showcase for Nvidia's RTX Remix technology. The software basically takes old games and adds ray tracing, the new standard for lighting in games. Ray tracing can provide virtual environments with incredibly realistic lighting and shadows, reflecting light beams off different surfaces in ways that are as true to real life as current technology allows.

Flawol warns us that this mod is "incredibly
