Nvidia has just released a new update for RTX Remix, its modding platform designed to retrofit old games with modern lighting and materials. RTX Remix 1.5 brings a bunch of improvements, but the highlight feature is the improved RTX IO storage compression that can cut down on the size of modded games. The update also adds agentic AI in the form of RTX Remix Skills, along with Smooth Normals for more natural-looking geometry.
Let's start with RTX IO, which is by no means a new technology — it was introduced back in 2020 with the RTX 30 series — but it's now integrated in RTX Remix. Upgrading old games with fully ray-traced lighting, along with sharper textures, skyrockets their sizes. The original assets aren't replaced either since RTX Remix intercepts the game at runtime and simply injects the new assets on top while suppressing the older ones.
