With RTX enabled, though, low-light areas receive physically-accurate lighting. Traditional global illumination often rendered these areas unnaturally bright. Metro Exodus’ post-apocalyptic world has plenty of low-light areas. This allows for some stunning and physically-accurate lighting effects, with light and shadow cast realistically on objects, characters, and the environment. All external world lighting–lighting cast by the sun–makes use of RTX. In Metro Exodus’ case, RTX is used to replace the game’s global illumination lighting system. Instead, they use conventional rasterized rendering with ray-tracing implemented to handle specific visual features. Ray-traced lighting completely changes how lighting looks in Metro Exodus This is because doing so would be too computationally expensive. Most RTX titles don’t make use of a fully ray-traced pipeline. It makes a strong case that hybrid ray-tracing might just be the future of visuals. But RTX lighting in Metro Exodus is a real game-changer. And, like I said, Nvidia does have a disreputable history of releasing performance-sapping, hardware-exclusive gimmicks. RTX has been (somewhat) justifiably criticized for being gimmicky. So, it makes sense to have a look at some of the other RTX-enabled games on the market. Control, the latest RTX-enhanced AAA title, is set to release on August 27th, 2019. Many of the games I’m looking forward to playing–like Cyberpunk 2077 and Atomic Heart–feature it. However, a wide range of studios appears to be adopting RTX. Initially, I was more than a little skeptical, considering Nvidia’s long and unsavory history of releasing hardware-locked “enhancements” that did little apart from sapping your performance (hello PhysX and Hairworks).

While it’s not a true implementation of ray-tracing as we see in CGI films, RTX offers a significant boost to visual fidelity in games that support it. However, this generation, Nvidia’s got something special up its sleeve: RTX ray-tracing. The top-end 5700XT delivered performance that often rivaled the monstrous GTX 1080 Ti. The recent arrival of AMD’s Navi cards–the RX 57 XT–offered a compelling reason to stick with them. I’ve been a long-time AMD fan and have owned several GPUs from Team Red, including the R9 Fury, the RX 480, and RX 580. I recently bit the bullet and bought an Nvidia RTX 2070 Super.
