ray tracing as an elaborate mod tools advert, I wouldn’t have gone for one with as timeless an aesthetic as Portal‘s. Maybe that’s why I’m not one – Portal with RTX is a gorgeous return to Aperture Science, a borderline must-play for anyone with a premium GeForce RTX GPU, and a mightily impressive demonstration of the Nvidia RTX Remix tools that built it.
Admittedly, that’s in spite of some shortcomings, including utterly broken performance on even the strongest Radeon RX graphics cards. Equip yourself with RTX hardware, however, and this free mod is a real Christmas treat.
