Portal, the first-person puzzle game that spawned a thousand memes, is getting a glow-up on December 8th, courtesy of a free piece of DLC. Portal with RTX was initially announced alongside Nvidia’s new RTX 4080 and 4090 graphics playing cards and provides ray-tracing assist together with remade hi-res textures and fashions to the sport. The result’s rather more practical lighting and reflections, making the 15-year-old title look nearly brand new.
