Portal Prelude RTX Remaster NVIDIA Steam
Powered by NVIDIA’s RTX Remix, Portal Prelude RTX remasters the original game and adds full ray tracing, DLSS 3 and RTX IO technology for AI-powered graphics. The storyline focuses on Genetic Lifeform and Disk Operating System (GlaDOS), an AI created by Aperture Science.



Software engineer Nicolas Grevet and modder Driver-Gomm transformed Portal: Prelude’s lower-resolution assets into new, high-resolution assets using RTX Remix. They made use of the NVIDIA GeForce RTX 40 Series GPU, which enables full ray tracing and DLSS 3. Download it here now.

The RTX Remix tool is insanely powerful and almost comes across as magic to me. The ability to capture any part of a game, load it in a 3D tool and chip away at it as if this was being done using the original game’s level editor is insane,” said Nicolas Grevet, Software Engineer for the Portal Prelude Project.
