This is the Ray Tracing We've Been Waiting For

Today, Nvidia showed us the true promise and vision of ray tracing—making virtual environments look as real as possible based on how light is cast and reflected off surfaces and It’s not a new concept. Animation studios like Pixar have been working with ray traced effects for years. But it’s always been easier to use those effects in an animated film because nothing needs to be rendered in real-time. Nvidia changed all that when it released its RTX 20-series graphics cards. For the first time ever, real-time ray tracing in video games was made possible. But it kind of sucked. Today Nvidia showed off what might be the ray tracing holy grail we’ve been waiting for.

Curated via Twitter from Gizmodo’s twitter account….

When Nvidia released its first ray tracing graphics cards two years ago, not only could you count the compatible games on one hand, but the lighting effects in those games were mostly limited to simple reflections or shadows. It was underwhelming.

According to Nvidia, the enhanced Marbles version is running at over four times the performance of the original version—easy to believe when you compare the day time lighting and shadows of the first version to the reflections, shadows, glow lighting, and other complex lighting effects of the new version.

Here’s a couple of screenshots from the original Marbles video rendered at 720p, 25 fps, and from the new Marbles video rendered at 1440p, 30fps, just to make a quick comparison. 720p, 25 fps with Turing graphics. 1440p, 30fps with Ampere graphics. 720p, 25 fps with Turing graphics. 1440p, 30fps with Ampere graphics.

It’s the same video but run on Nvidia’s Ampere architecture, which powers today’s new RTX 30-series graphics cards.

That’s because the original Marbles video was created with fully path-traced, photorealistic, real-time ray tracing graphics.
