Portal with RTX Now Available!
Portal with RTX free DLC is now available, featuring full ray tracing, performance boosting NVIDIA DLSS 3 , and the low latency with NVIDIA Reflex.
Portal with RTX is enhanced with full ray tracing, an advanced, GPU-intensive (see recommended & minimum specs here), version of ray tracing referred to as “path tracing” which unifies all lighting effects such as shadows, reflections, global illumination, refractions and more into a single algorithm. Gamers will get to enjoy Portal’s famous test chambers with every photon of light fully ray traced in real time!

Experience realistic lights that bounce off of every surface, and cast reflections on every object, from the iconic portal gun to the warped glass that lines every chamber in the Aperture Science Enrichment Center. Light even shines through portals!

And NVIDIA DLSS 3 delivers a 2.8x increase to frame rates, giving GeForce RTX 40 series gamers the performance to play Portal with RTX at 4K. Other GeForce RTX gamers will benefit from DLSS 2.
We also created some fun alternative cubes that can be unlocked by finding QR codes in the game. Scan them with your phone, press Alt + X in-game, click on Developer Settings, then go to About > Secrets, enter the code you see on your phone, check the box next to the new entry in the list, and all cubes will be switched to the custom cube you’ve unlocked.
With the DLC installed, you'll see it in your library as “Portal with RTX”, ready to be launched. Please ensure you have the latest GeForce Drivers installed and own the original Portal to play.
