Nvidia announced Portal: Prelude RTX, a new remaster of a popular 2008 mod that includes updated visuals in addition to support for raytracing and DLSS 3.
Nvidia said Portal: Prelude RTX is one of the first games (along with the PC port of Ratchet & Clank: Rift Apart) to use RTX Input/Output (RTX I/O), a new GPU-accelerated storage technology that supports Nvidia’s RTX GPUs aimed at reducing the time it takes to load large amounts of data like game assets and textures into memory for real-time rendering.
Portal: Prelude was released back in 2008 and served as an unofficial Portal prequel that included a new story with fully voiced NPCs along with new gameplay mechanics.
Portal: Prelude RTX is the first RTX-enhanced remaster made entirely by modders using the RTX Remix tool Nvidia announced last September. It’s an application that allows modders to pull game assets from older games and implement RTX tools, such as raytracing and DLSS.
Portal: Prelude RTX will release at 3pm ET today. And just like Portal RTX, those who own a copy of the original Portal on Steam can claim Portal: Prelude RTX for free.
