![]() ![]() Battlefield Vįor a long time there, Metro Exodus and Battlefield V were your only go-to options for RTX in games. It is truly something that you have to see for yourself. Even with the blocky models and cramped environs, the lighting just looks real in a way that no other’s game so far has managed to replicate. Ray-tracing simulates how light interacts in real life and the results in Quake II are photorealistic at times. ![]() It’s the only fully ray-traced game out right now. The alternative is just too taxing.īut let’s talk about Quake II RTX for a moment. This is why developers have opted for hybrid solutions, as seen in Metro: Exodus. And while it looks stunning, this relic from 1997 actually runs slower than today’s most punishing AAA titles like AC: Odyssey. Quake II RTX features a complete ray-tracing implementation. Quake II’s the only fully-raytraced game available. Today, the RTX 2070 Super, a card that is over 10,000 times faster (that wasn’t a typo), runs Quake II RTX at…well, roughly 60 FPS at 1080p. Paired with a Pentium II, the Voodoo 2 managed about 60 FPS on average at 800×600 with conventional, rasterized rendering. To put that into perspective, a budget mobile phone from 2010 like the ZTE Blade, has more graphics grunt. A fully ray-traced rendering pipeline makes Quake II thousands of times harder to run The 3dfx Voodoo 2, a top-of-the-line GPU from the era, had 8MB of VRAM and was clocked at 60 MHz. ![]() Quake II is an FPS that launched way back in 1997. Remember how I said most RTX implementations don’t have a fully-raytraced pipeline? If you were wondering why, Quake II RTX offers ample explanation. RTX 2070 Super can achieve a more or less stable lock on 60 FPS with RTX and DLSS turned on. However, DLSS upscaling offsets the performance impact somewhat. Metro Exodus is a demanding game to start off with and RTX incurs a significant performance hit on top of that. This is because RTX makes some areas so dark that you literally can’t see without an external light source. Artyom will have to use his flashlight much more often. Get out your lighters and flashlights: Dark areas get really dark with ray-tracing enabled 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. ![]()
