Let’s play a recreation of spot the distinction. Can you inform if the above video is a dwell motion scene from a current Star Wars film, or fully rendered in actual time within the Unreal four engine? That’s the great thing about lighting and reflections powered by raytracing.
This kind of picture constancy is why you want an excellent panel, so try our decide of at this time’s best gaming monitors.
We’ve already spoken about Microsoft and Nvidia announcing their real-time raytracing initiative, with the DirectX Raytracing API and the GeForce-exclusive RTX accelerator for the Nvidia Volta structure, and that is Epic taking it to its Unreal four limits.
The above video, referred to as Reflections, was created utilizing an $122,000 (£86,000) DGX Station mini server field, full of 4 discrete Tesla V100 graphics playing cards, to render all the demo in actual time. It’s working at 1080p and at a cinematic 24fps, and is barely distinguishable from a dwell motion scene.
Obviously at this stage that is showcasing what could be carried out within the film business, permitting graphics artists to render scenes in actual time, and permit them to edit them on the fly earlier than doing their closing move. When you want graphics horsepower that prices over $100Ok you’re going to wish a Hollywood price range.
But historical past has proven us that, when Epic collaborate with Nvidia to create showreel demos on a number of current-gen GPUs, it doesn’t take greater than a few years earlier than a gaming degree model seems on fashionable {hardware}. When we see this scene rendered with real-time raytracing on a single Nvidia Turing GPU we’ll know we’ve hit the motherlode.
Remember the Samaritan demo?
We are excited to share the information that we’re collaborating with @NVIDIAGeForce, utilizing their RTX real-time ray tracing tech in @MetroVideoGame! Stay tuned for our @Official_GDC demo within the coming days! https://t.co/5LTbY7DEHv

And whereas this demo is extra Hollywood than gaming, 4A Games are promising to indicate off their very own model of real-time raytracing, utilizing Nvidia’s RTX tech, in a Metro Exodus demo someday this week. Metro Exodus is launching later this yr, and can probably be one of many first video games to ever characteristic real-time raytraced lighting.
And I can not wait.
