NVIDIA's RTX Remix Skills lets modders without coding skills use AI agents to help remaster classic PC games

NVIDIA's RTX Remix continues to evolve and expand as more modders use it to breathe new life into classic PC games thanks to its ability to remake and rebuild games with modern path-traced lighting, remastered assets, and more. This week NVIDIA is releasing RTX Remix 1.5, which is available now via GitHub or through the NVIDIA App, and it brings several notable updates.

The first of which, and one that the RTX Remix community has heavily requested, is called Smooth Normals. Basically, this takes the blocky, polygonal look of classic PC games and lets modders make environments and objects look less blocky and more modern with path tracing.

The second notable update is the arrival of RTX IO support to speed up loading times, stream high-quality assets, and reduce overall mod install sizes. RTX IO leverages your GeForce RTX GPU for decompression, freeing up the CPU for other tasks, and it works with Microsoft's DirectStorage API. NVIDIA notes that notable RTX Remix projects on Steam, like Portal with RTX, Portal: Prelude RTX, and the Half-Life 2 RTX demo, all feature RTX IO.

And with that, Portal with RTX has seen its file size drop from 25GB to 17GB, while the Half-Life 2 RTX demo's file size has dropped from 80GB to 50GB.

But that's not all, as NVIDIA is introducing a new and powerful RTX Remix Skills feature that's a text-based set of instructions that deliver proper context to AI coding agents. "By making coding agents smarter, modders can accelerate the remastering process," NVIDIA explains. "This significantly lowers the barrier to entry: even without prior C++ or Python experience, users can act as creative directors, guiding AI agents to build meaningful upgrades within RTX Remix."

Very cool stuff, as it opens the door for more modders to remaster classic PC games. And with that, NVIDIA notes that, with RTX Remix Skills, modders have begun remastering iconic titles such as Dark Souls, Dragon Age: Origins, and Titanfall 2.
