Modder xoxor4d has released a groundbreaking compatibility mod that integrates Left 4 Dead 2 with advanced RTX Path Tracing technology. This mod enables RTX Remix support without altering in-game assets, delivering sophisticated ray-traced effects.

Most game objects rely on the conventional fixed-function pipeline, but this mod introduces dynamic lighting and lifelike reflections via Path Tracing. Despite lacking PBR textures and occasional minor visual glitches, it markedly enhances the game’s visual quality.

While no new textures are included, the visual upgrade is striking, particularly with ray tracing activated. The mod revitalizes the iconic cooperative shooter, appealing to players with modern hardware.

To install, download the latest version from the official link, extract the "l4d2-rtx" folder, and copy its contents to the root directory containing "LEFT4DEAD2.EXE".
