XIII Windows, Mac, RTX, XBOX, PS2, GCN game

It's been a couple of months since the release of NVIDIA's RTX Remix Open Beta, and in the time since dozens of modders have been posting configuration files and mods, enabling people to jump straight into classic games with path-traced lighting.

If you missed the announcement, RTX Remix consists of modding tools and revolutionary tech that allows you to play classic games with cutting edge technologies, and performance that's accelerated on GeForce RTX graphics cards by NVIDIA DLSS.

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 the path tracing. Then, 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 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.

Today, we're going to start looking at games enhanced with uploaded rtx.conf files, and at some of the work in progress mods that have been released or announced. If you're working on a mod you'd like featured, upload it 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.

Open Lara RTX: Reimagined Realms

Tomb Raider (1996)

• Status: Two-level demo
• Developer: Aureate_Games

Open Lara RTX: Reimagined Realms updates the groundbreaking, original Tomb Raider with fully path-traced lighting. Made by Aureate_Games, their downloadable mod is a fork of the Open Lara project, updated with RTX Remix technologies.

Featuring the first two levels of the game, Aureate's mod features modified and updated lighting, made using the Remix Toolkit, delivering a greater level of fidelity and quality. Additionally, some textures and objects have been updated to improve their interaction with the path-traced lighting, further enhancing the mod's visuals.

To try Open Lara RTX: Reimagined Realms for yourself, download the mod here and follow the installer's instructions to apply it to your copy of Tomb Raider (1996) from Steam or GOG.

XIII

XIII (2003)

• Status: Playable with rtx.conf
• Developer: Jacob Freeman

"The President of the United States of America has been assassinated and you're the world's prime suspect. Stricken with amnesia you remember nothing, not even who you are. You're on your own and there is no one you can trust. All you have is a safe deposit key, a mysterious tattoo, and a gun. Clear your name, solve the mystery, and catch the true assassin before he strikes again."

XIII [thur-teen] was a unique first-person shooter upon release in 2003, featuring comic book-style cut-outs, picture-in-picture comic-styled panels showing special events and unique moments, and original gameplay ideas, such as being able to pick up chairs and other objects and use them as near-silent weapons on unsuspecting enemies.

This much-loved game received community updates as late as 2019, culminating in the release of the XIII All-In-One Installer, which is a recommended download for anyone playing XIII today.

See how RTX Remix enhances XIII's opening levels in the 4K screenshots below:

To play XIII with NVIDIA RTX Remix enhancements, download the rtx.conf here, then download remix-0.4.1-release.zip (or a newer version) from the official RTX Remix Github. Place the contents of the Remix Runtime .zip alongside XIII's game .exe, and drop the rtx.conf there, too.

We also recommend installing the aforementioned XIII All-In-One Installer for 16:9 support, and to improve the results when using Jacob's rtx.conf.

If you're a fan of XIII and would like to contribute an updated rtx.conf based on Jacob's upload, you can share it via this link.
