NVIDIA’s RTX Remix Open Beta recently received a massive new update, adding out-of-the-box support for NVIDIA DLSS 3.5 with Ray Reconstruction, new modding capabilities, image quality enhancements, and much more. RTX Remix consists of modding tools and revolutionary tech that allows you to play classic games with fully ray-traced (path-traced) graphics, and performance that’s accelerated on GeForce RTX graphics cards by NVIDIA DLSS.

Recently, we took a look at some of the first RTX mods available to download. This month, we’re looking at one for Need For Speed: Underground. Additionally, there are now over 150 rtx.conf files uploaded to ModDB - these enable you to play a compatible game with full ray tracing in mere moments, and offer a great foundation for full-on RTX Remix modding.

The Making Of A RTX Remix Mod

Through an intuitive GUI modders can create rtx.conf files that tell the RTX Remix Runtime how to render the game. For example, by clicking a few boxes you can define detected textures as user interface elements, and others as water or terrain. All of these changes are saved to the few-kilobyte configuration file that you can upload and share on ModDB.

Via the RTX Remix Toolkit, modders can edit the contents of each game, replacing basic lights with more advanced and realistic solutions, and adding new features that synergise with path tracing. The next step is to upgrade and replace textures, either using Remix’s built-in AI features or by making them in Adobe, Blender, or other NVIDIA Omniverse-connected applications.

This is how NVIDIA Lightspeed Studios made Portal with RTX, and with enough time and skill, a modder could make something equally as impressive for any of the RTX Remix-compatible games. Via the Remix Toolkit, your awesome mod can be packaged as an installable file for easy sharing right here on ModDB.


If you’re working on a mod you’d like featured, upload it to ModDB and get in touch.

To try one of the mods or configuration files that other modders have already shared, head to the RTX Remix-Compatible Games List and download via the hyperlinks on the far right of the filterable table.

Need For Speed: Underground RTX

NFS Underground RTX v0.0.4a


This much-loved racing game is back on the streets thanks to alessandro893’s RTX Remix mod. In active development, much of the game’s lighting has been fully ray-traced, over 1,000 additional lights have been added to the world for improved image quality and immersion, and many textures have been enhanced.


Elements such as car headlights have yet to be ray-traced, but already the mod made by a single author is showing great promise, and you can follow its development on the RTX Remix Showcase Discord.

If you want to play the Need For Speed: Underground mod, head to our ModDB page and select the latest release from “Files”. Download the .zip, and click on “Read more…” in the Description section for installation instructions for that particular version.

Once setup is complete, you can race around Olympic City with visuals like these:

Something is off ... the cars look like they are made out of rubber, the car reflections in vanilla look better. Isn't the point of RTX to add ray traced reflections?

Did you edit resolution in "scripts/NFSUnderground.WidescreenFix.ini" ? It is set to 4k by default.
