NVIDIA RTX Remix 1.5: Remastering is Possible Even for Those Who Don't Know Python and C++

NVIDIA has announced the release of RTX Remix 1.5, an update to the modding platform dedicated to classic PC games and designed for systems equipped with GeForce RTX GPUs. The new version introduces a series of features aimed at simplifying the remastering process and improving performance and compatibility.

One of the most requested interventions by the community is the arrival of Smooth Normals, a feature that automatically generates natural bevels for the geometry of older titles. The result is assets that appear less angular and more natural when illuminated using path tracing, the technology at the heart of the graphical experience proposed by RTX Remix.

The update also introduces a faster and compatible Runtime, as well as a more streamlined mod packaging process within the Remix Toolkit. NVIDIA has also integrated new compression options for RTX IO, the proprietary technology that speeds up game loading, reduces CPU load, and improves high-quality texture streaming.

The integration of RTX IO has already been implemented in Portal with RTX, Portal: Prelude RTX, and the demo of Half-Life 2 RTX. The benefits are also evident in terms of disk space. Portal with RTX goes from 25 GB to 17 GB, while Half-Life 2 RTX drops from 80 GB to 50 GB.

RTX Remix 1.5 also introduces an updated system for managing light sources within the viewport. The controls are now gathered in a unified menu that allows for easier management of the visibility of manipulators and the intensity of lights.

Among the most interesting new features is support for AI-based agents. NVIDIA has published several RTX Remix Skills, text instruction files that provide context and operational guidance for AI-based coding tools. The instructions cover tasks such as creating development branches, running tests, and preparing merge requests.

According to NVIDIA, the use of AI-based agents significantly lowers the barriers to entry for modding. Even users without experience in C++ or Python can oversee the creative process and guide automated tools in making significant updates.

The company also cites some practical examples. Converting modern games, which use programmable graphics pipelines incompatible with Remix, is normally a complex and lengthy process. However, some community members have leveraged the agents based on Remix Skills to automate compatibility checks and code generation, reducing work times from months to just a few weeks.

This approach has already allowed the community to begin work on titles that were previously unsupported, including Dark Souls, Dragon Age: Origins, and Titanfall 2, further expanding the possibilities offered by NVIDIA's remastering platform.
