Nvidia is bringing ray-tracing to Portal with an RTX version

Nvidia has announced Portal RTX, an official mod for the Valve puzzle game made using RTX Remix, a new platform that will allow users to inject RTX lighting into classic games.

According to Nvidia, RTX Remix can “can add ray tracing with just a few clicks, and gives modders the tools to make ambitious remasters, even for games that were previously unmoddable.”

Announced during GeForce Beyond, the mod will be free to owners of the game on PC when it releases in November.

“This RTX upgrade builds-upon our work on Quake II and Minecraft, but is extra special, as the tool used to make Portal with RTX will be released for free, allowing you to give the RTX treatment to other classic games,” reads a statement from Nvidia.

Nvidia has also created new assets for the game, which it claims are in the spirit of Valve’s original work.

“Every frame of gameplay is upgraded with stunning full ray tracing, new, hand-crafted hi-res physically based textures, and new, enhanced high-poly models evocative of the originals.

“Performance is accelerated with NVIDIA DLSS 3, allowing the game to run incredibly smoothly, and system latency is minimized using NVIDIA Reflex. And it was all built collaboratively by NVIDIA Lightspeed Studios.”

Portal, which originally appeared as part of Valve’s The Orange Box, is a puzzle game that sees the player navigate through environments by opening and closing portals that they can walk through.

The game also leverages a darkly humorous narrative as players adventure and puzzle their way through the mysterious Aperture Science Laboratories.

During the stream Nvidia also the latest generation of its graphics cards, headlined by the Nvidia RTX 4090.
