NVIDIA GeForce News:

NVIDIA RTX Remix enables modders to reimagine classic games with full ray tracing, also known as path tracing, and to update models and textures with modern rendering features that work hand in hand with ray-traced effects to deliver the level of graphical fidelity seen in Portal with RTX, our ray-traced reimagining of Valve’s classic game. And with a few additional clicks, support for NVIDIA DLSS and NVIDIA Reflex can be introduced, accelerating performance and making gameplay even more responsive.

Following the launch of the RTX Remix Open Beta in January, we’re today introducing new features and optimizations, headlined by the addition of NVIDIA DLSS 3.5 with Ray Reconstruction, an AI model that creates higher quality ray-traced images for intensive ray-traced games and apps.

Additionally, we’re taking a look at some work in progress RTX Remix mods, and checking in with Half-Life 2 RTX: An RTX Remix Project, to demonstrate the toolkit’s capabilities.

NVIDIA RTX Remix Upgrades To DLSS 3.5 With Ray Reconstruction

Last month, we updated Portal with RTX to add support for NVIDIA DLSS 3.5 with Ray Reconstruction. This advanced AI-powered neural renderer improves upon previously available rendering techniques to heighten the fidelity, responsiveness and quality of ray-traced effects, giving all GeForce RTX gamers an even better experience.





Now, DLSS 3.5 with Ray Reconstruction has been added to the NVIDIA RTX Remix modding toolkit, opening the floodgates for many more classic titles with higher quality ray-traced images. With just a few clicks, RTX Remix mods can be updated to DLSS 3.5, enhancing ray tracing as in Portal with RTX.

DLSS 3.5 with Ray Reconstruction is especially helpful in a modding tool like RTX Remix, since it tackles a variety of content that would be normally challenging for traditional hand-tuned denoisers. Modders don’t need to worry about hand-tuning environments for different scenes and lighting conditions–the AI model powering Ray Reconstruction has been trained on a variety of scenarios already, and can adapt automatically.


Comparison from Half-Life 2 RTX: An RTX Remix Project

In addition to adding Ray Reconstruction to the Remix Open Beta, we’re introducing new Toolkit and Runtime enhancements that improve mod image quality, expand compatibility, and make the modding process easier. Five of these changes come from our GitHub community, who contributed new code that has now been incorporated into Remix:

• Mod developer “pixelcluster” improved how well RTX Remix mods run for Steam Deck and Linux AMD users, thanks to optimizations for RADV drivers
• Mod developer “mmdanggg2” made improvements to the consistency of distant lights, making them update properly when changing or reorienting them
• Mod developer “jdswebb” made improvements to how terrain baking and other features work with games that use a left-handed coordinate system
• Mod developer “xoxor4d” made several improvements that streamline the texture tagging process, which is essential to properly setting up a game with RTX Remix
• Mod developer “xoxor4d” also added an option to use AABBs to differentiate instances, and therefore track them better across frames. For gamers, that means less ghosting and flickering for animated objects and skinned meshes in motion. See the difference in the example from a test scenario below.

If you are a mod developer interested in collaborating with us to make RTX Remix even better, learn how to contribute code on our RTX Remix Open Source GitHub.



If you’re a modder with the RTX Remix beta, install the latest update by opening the NVIDIA Omniverse Launcher, and clicking the menu next to the “Launch” button. Updating the RTX Remix Application also gives you the latest RTX Remix Runtime that contains DLSS 3.5 Ray Reconstruction, or you can download the latest release of the RTX Remix Runtime from GitHub.

Replace the old RTX Remix Runtime in your mod projects and give all of your players access to Ray Reconstruction by following the instructions here.

If you are interested in trying the RTX Remix beta for the first time, download and install the NVIDIA RTX Remix Open Beta for access to all of its features, including its generative AI tools that can enhance textures by increasing their resolution and adding PBR material properties.
