en.Wedoany.com Reported - Nvidia recently released the RTX Remix 1.5 update, a modding platform designed to add modern lighting and material effects to older games. Key improvements in RTX Remix 1.5 include the introduction of RTX IO storage compression technology to reduce the size of modded games, the addition of an AI agent (RTX Remix Skills), and a new Smooth Normals feature that makes geometry appear more natural.

RTX IO is not a brand-new feature; it was introduced with the RTX 30 series in 2020 and has now been integrated into RTX Remix. When upgrading older games with full ray-traced lighting and sharp textures, the game size can increase significantly. RTX Remix intercepts the game at runtime, injecting new assets from an overlay while suppressing old ones, without replacing the original assets. The newly added compression options effectively reduce file sizes during the packaging process. Currently, this feature is supported in Portal with RTX, Portal: Prelude RTX, and the Half-Life 2 RTX demo. The Half-Life 2 RTX demo was reduced from 80GB to 50GB, a decrease of 37.5%; Portal with RTX was reduced from 27GB to 17GB.

RTX Remix 1.5 also offers the Smooth Normals feature, which was highly requested by the community. When older geometry is upgraded to modern lighting, some elements can appear blocky. Smooth Normals improves the appearance of assets by automatically generating smooth normals, eliminating the need for manual adjustments.

RTX Remix Skills is now available on the platform, allowing users to accelerate workflows through an AI agent. Nvidia positions it as a tool to lower the barrier to modding, usable even without coding experience, and suitable for remastering modern games without fixed-function pipelines. It is reported that Dark Souls, Dragon Age: Origins, and Titanfall 2 are being upgraded through this method.

RTX Remix is currently publicly available and open-source. Users can play modded games even without an Nvidia GPU, with a wide selection available on ModDB. However, developing or creating mods still requires an Nvidia GPU, and users can obtain RTX Remix directly from the Nvidia App. For users who prefer a coding agent, the Remix agent instruction files have been released on GitHub.
