Portal: Prelude, a Portal mod made by Nicolas "Nyk018" Grevet, just received the RTX remaster treatment 15 years after its initial release. The mod now includes full path tracing, DLSS 3, and Nvidia Reflex support. It also achieves a first for PC gaming: it's the first game to support RTX IO, Nvidia's implementation of a new standard aiming to speed up texture loading times and reduce file sizes.
Portal: Prelude RTX is available from today over at Steam. Any RTX-branded GPU will seemingly be able to run the game—an RTX 2060 is the minimum requirement, though you'd likely require more power to really kick path tracing into overdrive.
