Nvidia updates the original Portal with ray tracing graphics

Ray tracing, a next-generation lighting technology that creates hyper-realistic visuals, has been the hot topic in gaming graphics for a while. The most interesting aspect is that real-time ray tracing doesn't require spiffy new gaming engines or setups -- you can apply it to super-basic 3D titles like Minecraft or even the original Doom. As part of its RTX 4000 series announcement, Nvidia showed off an updated version of Valve's classic Portal, a first-person puzzler, with a ray tracing lighting mod and DLSS 3 applied. Nvidia isn't the first to apply ray tracing to Portal, but its new version of the game consistently applies the lighting technology to the entire game. This enhances the original title's bleak atmosphere and the super-clean testing facility and its dark, foreboding underbelly.
