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 full ray tracing, DLSS 3 for increased performance and RTX IO for quicker load times.
Looks amazing, definitely going to give it a try. I never got around to play the originals but ya know, free is free.
