UPDATE: 4A Games has taken the wraps off its Nvidia RTX real-time ray tracing tech demo for the upcoming Metro Exodus, revealing a full camera pan through a post-apocalyptics village.
Unlike the other tech demos we’ve been spoon fed though, the difference here is this how real-time ray tracing looks in games right now, and toned down so it can run on off-the-shelf hardware. The full capabilities of RTX won't be used for quite a while, but in this demo, we see raytraced ambient occlusion and indirect lighting effects. Naturally, it falls a long, long distance short of the Star Wars real-time ray tracing demo, but the results can be undeniably impressive, if a little mixed.
The indoor environments look absolutely fantastic, particularly with the lighting pouring in and the realistic shadows being cast. However, a real low point has to be the river during the opening portion of the sequence. The reflections look extremely over the top and frankly a little ridiculous. Hopefully, 4A Games can find some time to tone that effect down between now and launch.
“Dynamic lighting has always been a priority for the Metro series,” says 4A Games CTO, Oleksandr Shyshkovtsov. “We intentionally avoided pre-baked data and were relying on real-time methods to build our visuals to support more flexible, dynamic gameplay. Global Illumination is highly important for the proper "grounding" of objects and readability of shapes, which in turn create improved ease of navigation and enhanced visual impact for the player.
“Previously, we had utilized a mix of several custom-made systems to satisfy our hungry demand for dynamic content of varying scale. Now we are able to replace it with one single system that covers all our needs and outputs the quality of offline renderers.”
Nvidia RTX will only be compatible with the upcoming generation of GeForce GPUs, rumoured to be Turing, prompting speculation that Metro Exodus may be launching around the same time as Nvidia's new graphics cards. I don't think I can think of a better game to bundle in with a new GeForce GTX 2080 purchase.
Original Story: 22-Mar-18 - Metro Exodus Will be the First PC Game to Use Nvidia RTX Real-Time Ray Tracing
Metro developer 4A Games knows a thing or two about graphical showcases. Both Metro 2033 and Metro: Last Light were capable of absolutely crunching even the best gaming PCs when they launched, and we expect Metro Exodus to be no different. Right on cue, 4A Games has announced at GDC 2018 that Metro Exodus is the first PC game to officially support the ultra-demanding Nvidia RTX real-time ray tracing technology.
4A Games announced the collaboration with Nvidia GeForce on Twitter, and has also promised that an official tech demo for Metro Exodus will be revealed at GDC within a matter of days.
Nvidia RTX real-time ray tracing allows for cinematic-quality photorealistic rendering of lighting, including ray-traced shadows, ray-traced ambient occlusion, and ray-traced reflections. At the moment the technology is exclusive to Nvidia Volta GPUs and upwards, so it’s going to be out of reach for most, but it is a tantalising prospect that Metro Exodus with have graphics settings far beyond what most GPUs are even capable of today.
As if it was ever in doubt, one thing’s for sure - Metro Exodus is going to be the new standard bearer for PC performance tests. We’ll be sure to bring you the GDC 2018 Metro Exodus RTX tech demo as soon as we hear about it.
Metro Exodus is due to launch later in 2018 for PC, PlayStation 4 and Xbox One.
