![]() ![]() ![]() 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. ![]()
