Nvidia has released a new feature that, if it works as described and takes off, can transform game development. In particular, 32-bit-based PC games running DirectX 8 or 9.
Nvidia has developed Nvidia RTX Remix, a program that allows users to remaster supported DirectX 8 or DirectX 9 games with fixed function graphics pipelines.
The program was created as a response to a graphic card processor (and now an AI solutions company) that worked on Quake II to support ray-tracing capabilities and promote the first RTX 20 Series cards. It's tough for them, even since they had access to all the source code.
RTX Remix's purpose is to "capture" graphical assets from supported games. This is done by the RTX Remix Runtime, which intercepts draw calls from the D3D9 runtime. The captured visual assets may then be imported to the Nvidia Omniverse platform's Universal Scene Description (USD) 3D framework.
The assets may be imported to any other Omniverse app or connector, including industry-standard software like Adobe Substance 3D Painter, Autodesk Maya, Blender, SideFX Houdini, and Epic Games' Unreal Engine.
The workflow is designed for collaboration, so mod teams may easily enhance the captured assets together.
It's not just the textures and models that are included. Modders may also add ray-tracing and other graphical effects to the environment.
With this tool, games such as Mount & Blade and Elder Scrolls III: Morrowind can now have ray-tracing modifications, and the additional lighting effects make the rather dark and muddy-looking graphics (by today's standards) much more pleasant.
Given the complexity of mod making (and game making) in general, this sounds almost too good to be true. In a way, RTX remixing sounds as if it's easy, especially if modders find it as easy as being presented here.
On those games, Nvidia showed examples of RTX Remix in action, but the game that has completed this feature is Valve's Portal.
This November, Portal With RTX will be released for free for those who own the game. Nvidia used RTX remix to create Portal with RTX.
Of course, Nvidia had included ray-tracing in Minecraft earlier.
