NVIDIA drops remake of fan-favorite mod ‘Portal: Prelude’ on Steam for free

There's full ray tracing, updated textures, new lighting and much more.

Portal: Prelude

NVIDIA just officially released the 2008 fan-made Portal mod, Portal: Prelude. The company dropped it on Steam and, what’s more, it’s free for anyone who has the original game. This isn’t a drab re-release, as the updated release features new textures, full ray tracing, DLSS 3 for increased performance, NVIDIA Reflex for decreased latency and RTX IO for quicker load times.

NVIDIA also dropped a GeForce Game Ready Driver to simplify setup. All of the changes to the remaster were done by modders, keeping with the spirit of the original release, via the company’s forthcoming RTX Remix creator toolkit. NVIDIA also hired famed modders to modernize assets and improve the lighting.

For the uninitiated, Portal: Prelude was originally released back in 2008 and developed by modders. It acts as a prequel to the original game and is set before the time of GLaDOS. The game offers a ten-hour campaign with nearly 20 test chambers, a fully voiced story and mechanics that go beyond the first Portal. It continues to be the highest-rated Portal mod, and there’s no shortage of competition.

This remake took eight months of dev time and acts as a showcase for the aforementioned modding toolkit, RTX Remix. Portal: Prelude is available right now on Steam and won’t cost you anything, as long as you have the original Portal, so get downloading.
