NVIDIA’s RTX Remix game modification tool has entered open beta testing, making it available to all users interested in remastering classic DirectX 8 or 9 games, according to Tom’s Hardware.
Previously only available through NVIDIA-sponsored mods such as Portal RTX, this tool allows users to enhance older games with modern textures, resources, and advanced lighting with trajectory tracking.

RTX Remix is similar to Unreal Engine 5 for game modification, allowing you to create high-quality remasters of classic games with modern graphics and ray tracing. The tool has a graphical user interface (GUI) that simplifies the modification process without requiring deep programming knowledge or familiarity with the game’s source code.

However, RTX Remix is not a simple one-click solution. NVIDIA emphasizes that although the tool makes modding more accessible, it still requires time and dedication to create a quality remaster. The program contains various tools for sharing resources and replacing old lighting systems with new simulations with ray tracing or contours. It also supports the OpenUSD file format, which allows you to use third-party programs such as Blender or Adobe Substance to create assets.

One of the features of RTX Remix is an artificial intelligence texture generation tool that automatically enhances old textures, giving them higher resolution and physical accuracy for better interaction with ray tracing. The open beta also introduces Parallax Occlusion Mapping, which adds 3D properties to old 2D textures.

Modders can test their work in real time using the runtime feature in Remix. System requirements to use RTX Remix include a 4-core Intel Core i7/AMD Ryzen processor or better, 16GB of RAM, 512GB SSD storage, and at least an RTX 3060 Ti GPU thanks to integration with NVIDIA Omniverse.

NVIDIA has demonstrated the capabilities of RTX Remix in projects such as Portal: RTX and the upcoming Half-Life 2 RTX from Orbifold Studios. Since the tool is currently in open beta, it will be interesting to see how it works in real-world scenarios with modders of different experience levels.
