In Portal, players control a test participant in the Aperture Science Enrichment Center. Using the "Aperture Science Handheld Portal Device", players perform a variety of tests, such as creating portals to knock over turrets and other objects or moving to a previously unreachable area. Guided by an electronic female voice that is at once both comical and subtly threatening, players must either complete these objectives or fail the test. Failure or refusal of a test likely results in death, although it may not be permanent. In Nov/2022, Portal with RTX, a free DLC was released that reimagined the game with ray tracing. Every frame of gameplay is upgraded with stunning full ray tracing, new, hand-crafted hi-res physically based textures, and new, enhanced high-poly models evocative of the originals, all in stunning 4K. Full ray tracing transforms each level, enabling light to bounce and be affected by the scene’s geometry and materials. Every light is ray-traced and casts shadows, global illumination indirect lighting naturally illuminates and darkens rooms, volumetric ray-traced lighting scatters through fog and smoke, and shadows are pixel perfect. It's compatible with all ray-tracing capable GPUs. |
