Overview
- NVIDIA has publicly released RTX Remix 1.5, which adds a new RTX IO compression model integrated into the Remix packaging workflow to compress remastered assets.
- The company says the compression has already reduced packaged sizes for example titles, with Portal with RTX reported to fall from 25 GB to 17 GB and Half‑Life 2 RTX from 80 GB to 50 GB.
- New packaging presets let modders split packages between 1 GB and 16 GB to make downloads and distribution more manageable.
- RTX Remix 1.5 also adds modding tools requested by the community, including automatic Smooth Normals to smooth older geometry and improved viewport light controls for easier lighting edits.
- NVIDIA published 'RTX Remix Skills' text files that give AI coding agents actionable instructions so automated tools can handle routine steps in the remastering pipeline, a change that could lower technical barriers for modders and speed workflows.
