About the Game

Portal with RTX is a free DLC for all Portal owners developed by NVIDIA Lightspeed Studios. Experience the critically acclaimed and award-winning Portal™ reimagined with ray tracing and NVIDIA DLSS 4 with Multi Frame Generation 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. 

In Portal with RTX, 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. The addition of RTX Neural Radiance Cache also enhances the quality of ray-traced indirect lighting, while improving performance resulting in a more accurate and responsive lighting model. Portal with RTX is compatible with all ray-tracing capable GPUs.
