Valve's classic puzzle platform game "Portal" (opens in new tab) has been fully remodeled in the Nvidia way, with support for ray tracing and DLSS 3 (opens in new tab) Created in-house at Nvidia's Lightspeed Studios The game, known as "Portal with RTX," will be available as a free DLC add-on to the original game starting December 8.

Believe it or not, this release coincides with the 15th anniversary of Valve's release of Portal in 2007. Yes, Portal is really old. So are we; even Portal 2 is 9 years old. (Open in new tab) Terrible.

Anyway, the entire game has been reworked with ray-traced lighting, new high-resolution textures and polygon-heavy 3D models. In addition, full support has been added for both DLSS 2 and DLSS 3, Nvidia's resolution scaling and performance enhancement platform.

DLSS 2 functionality is available on RTX 30 series graphics boards, while DLSS 3, including frame insertion, is exclusive to the latest RTX 40 series GPUs, including the powerful GeForce RTX 4090 (open in new tab).

It is not immediately clear if the new visuals will be supported on AMD hardware. However, expect ray tracing, fancy textures, and nifty high-poly models to work on AMD GPUs. We just won't be able to use the DLSS sizzle. For more info on system specs required, click here. (opens in new tab)

Of course, the entire game has been carefully coded to run on Nvidia GPUs. In celebration of all of the above, Nvidia will be giving away a behind-the-scenes look at the making of Portal with RTX, new gameplay, special surprises, a Portal game code giveaway, and GeForce RTX 4090 and GeForce RTX 4080 graphics cards, and a chance to win an online Portal with RTX party.

We might even dive in with an upgraded 4090 review unit.
