Welcome to my full run/walkthrough of Portals RTX mod on steam! This mod overhauls the classic Portal experience with new lighting/shading resources!
Experience the critically acclaimed and award-winning Portal™ reimagined with full ray tracing and DLSS 4 in this free DLC for Portal owners. Start thinking with portals, with RTX on.
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.
Some Full Games may have Commentary versions posted on my other channel. If there is a commentary version available I will post it here.
All games are recorded in 4K 60FPS using an Elgato 4K and a Dual PC setup. PS5 Gameplays are recorded the same way.
My PC Specs:
Ryzen 7 5800X3D
ZOTAC RTX 4070 Ti
32GB DDR4 Corsair RGB RAM (3600MHZ)
Rift S VR Headset
