Nvidia's RTX Remix platform, which transforms old games with path tracing, has so far been incompatible with FromSoftware's cult action RPG Dark Souls, but a group of enthusiasts has made the impossible possible.

Path-traced Dark Souls was made possible thanks to a toolset by Ekozmaster and Kim2091 (created using agent-based engineering), a codebase by xoxor4d, and contributions from CR. The result was demonstrated by modder gabdeg.
A 17-minute video posted on the YouTube channel gabdeg demonstrates how path tracing transforms iconic locations from Dark Souls: Prepare To Die Edition, such as the Undead Burg and Anor Londo. The video is riddled with bugs, however.

Dark Souls Remastered, released in 2018, includes these maps, but is based on DirectX 11 (RTX Remix works with DirectX 8 and 9 games), so Prepare To Die Edition was the modders' only option.

"Oh my god, I've been struggling to even get PTDE to run with RTX Remix after every API update. Honestly, this is my dream mod," admitted fromsoftserve.
It's worth noting that gabdeg is planning a public release of his Dark Souls RTX Remix mod. Before the release, the enthusiast intends to improve the build's stability and fix the most obvious graphical issues. A release date has not been specified.
