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.
- Aspect Ratio:16:9
- NVIDIA GeForce RTX 3050 4GB GDDR6 Graphics up to 1600MHz at 60W (75W with Dynamic Boost 2.0)
- Intel Core i5-11400H Processor (12M Cache, up to 4.5 GHz, 6 Cores)

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.
