NVIDIA introduces RTX Remix, an automated utility for creating RTX remasters of old games

At the presentation of the GeForce RTX 4090 and RTX 4080 graphics cards, NVIDIA introduced the RTX Remix AI utility, designed to help you create mods and remasters of old games. It should make it easier for modders to work with classic games and provide simple, automated methods for improving graphics and details, as well as adding support for ray tracing and DLSS.

In older games running on the DirectX 8 or DirectX 9 libraries, RTX Remix lets you capture scene data at the touch of a button, solving one of the most difficult tasks of creating mods. The utility intercepts all draw calls, thereby gathering information about textures, geometry, lighting, and cameras. All of this data is then converted to the universal USD (Universal Scene Description) format used by the NVIDIA Omniverse platform. Scene descriptions in this format can be easily exported to popular 3D modeling tools, where they can be modified and revised.

When creating remasters of old games with additional ray tracing, it is necessary not only to improve the quality of textures, but also to give them physical properties, improve details, add new objects and even change surfaces with normal map correction. RTX Remix also adds automation at this stage. Using AI algorithms, the utility is able to increase the resolution of textures and add physical properties to materials automatically, thereby relieving the modder of a large amount of routine tasks. RTX Remix also includes lighting customization features that allow you to create full-fledged realistic lighting with shadows and reflections instead of the primitive ambient lighting of older games.

After that, RTX Remix packages the finished mods into a format that can be distributed among gamers. The mods created in the utility replace old API calls with a new rendering library that works through Vulkan. This allows you to completely replace the rendering pipeline and not only add ray tracing and other modern visual effects to modified games, but also support, for example, NVIDIA DLSS 3 technology.

The RTX version of Portal announced today is said to have been created using the RTX Remix.

NVIDIA also showed an example of a scene from The Elder Scrolls III: Morrowind, also recreated using the RTX Remix utility.

It is assumed that the RTX Remix utility will be distributed free of charge. However, when it will be available to the general public is unknown. In addition, apparently, RTX Remix will not be able to work with all old games, only with a certain list of “supported”. However, there is no concrete information on this yet.
