Portal: Prelude RTX Now Available

Portal with RTX · published 18 Jul 2023, 19:48 UTC

All newsPlayers around this dateRead on Steam

Portal remains a timeless classic; in December we released Portal with RTX, a fully ray-traced reimagining of Valve’s award winning game, which used the performance multiplication of NVIDIA DLSS 3 to power the most realistic path-traced lighting ever seen in a real-time game.

Portal with RTX was created using NVIDIA RTX Remix, a free, upcoming modding platform built on NVIDIA Omniverse, which enables modders to quickly create and share #RTXON mods for classic games, each with enhanced materials, full ray tracing, NVIDIA DLSS 3, NVIDIA RTX IO, and NVIDIA Reflex.

Now, RTX Remix has been used to remaster Portal: Prelude, the highest rated Portal mod, the 2008 Portal ModDB winner, and #3 overall Player’s Choice mod of 2008. Created by Nicolas “NykO18” Grevet and others, Portal: Prelude is an unofficial Portal prequel, set before the time of GLaDOS, featuring a new extremely challenging 8-10 hour campaign composed of 19 new test chambers, new advanced gameplay mechanics, a fully voiced story with NPCs, and a whole lot more.

Portal: Prelude RTX is available today to download from Steam, for free!
