Nvidia makes mod tools available for adding path tracing to old games

Nvidia has made its RTX Remix software open source available on GitHub. The software should make it possible to process path traced lighting, DLSS and Nvidia Reflex in DirectX 8 and 9 titles. For example, Portal RTX was also created with the tool.

An important side note is that the RTX Remix toolkit consists of two parts: the creator toolkit and the runtime. At the time of writing, Nvidia only has the runtime made available on GitHub. This makes it possible to add path-traced lighting, DLSS and Reflex to a game, but adjusting surfaces and models, for example, is not yet an option. In the readme, Nvidia writes that a mod maker “doesn’t have to be an expert,” but that “understanding some of the key concepts and components and how they connect will make it easier to understand the workflow.”

Examples of games that have received Nvidia’s “RTX treatment” include Portal, Minecraft, and Quake II. The RTX Remix creator toolkit should be released “soon,” Nvidia said in a statement announcement which has been put online by Videocardz, among others.

Interested users had already started working on the Portal RTX binaries. It turns out that games running on DirectX 8 or 9 can also receive the same RTX treatment using those files. Users share their results and those of this new runtime on /r/RTXRemix.

Some of these tools are therefore not yet available.
