From game and engine support to compatible hardware – helped along by next-gen consoles sales – we will see at least an increase in opportunity for ray tracing in 2020. With AMD’s ray tracing smarts somehow equipping the RDNA architecture with all it needs to render rays in real-time, it’s the key to a wider remit of developers and consumers across formats. The balls on the right went over the roughness threshold, so were replaced with Enlighten's cubemaps. Without Enlighten, ray tracking reflection is 1.72ms, but it only rises to 1.87ms after Enlighten is introduced, so the cost of adding Enlighten is fairly small. Here is us rendering just the lighting part: With Enlighten, the indirect lights from the directional light and skylight are updated in real time. Starting with Enlighten 3.12 release, support for ray-traced Enlighten visibility and combination of ray tracing reflection and enlighten will be offered in early access.

Jacob describes himself as the hardware team’s resident wildcard. In terms of performance, with Final Gather alone, we see a 3.06ms for the Create Gather Points path, whereas with Enlighten that rises to 3.58ms, so the costs are, once again, relatively insignificant.

And despite the game itself feeling somewhat classical, to put it bluntly, it’s also interesting how much DNA from current open-world games can be found here. You can also see bounces from the train, which is the moving object. Look at the screenshots, the upper one indicates the result after Enlighten was added. There are no comments on this article yet. You can then obtain indirect light results of the Screen Pixel. The tech doesn’t come cheap and the effects aren’t always all that spectacular. In terms of performance, we used the same scene to compare performance before and after Enlighten is added. As it only simulates the first light bounce, it is often used in conjunction with another global illumination.

Melbourne, Australia. And then there's ray tracing. It looks very impressive, and with improvement in GPU, it's becoming a reality in modern games. By combining both, you can get Enlighten's infinite bounce alongside Final Gather's beautiful first bounces, plus light can bounce of moving objects. At least it runs pretty well on Nintendo Switch!

In UE4's Final Gather implementation, rays are transmitted from pixels on the screen. Perhaps surprisingly, Minecraft RTX is perhaps the most stunning of all ray tracing titles slated for 2020. Perhaps. This created 40,000 sampling points, which means you have 40,000 shadow rays, and using a GeForce RTX 2060, it took 0.04ms to process. The ball in the center shows specular reflection. We could be in for a banner year for real-time ray tracing. It has no limitations like with SSR, and its reflection fills the entire scene, giving beautiful results. The good news is that the game looked solid even with the settings locked into the middle ground, making Crysis Remastered to look like a very attractive modern game with some very dated design decisions and animation. However, with the blue train being a moving object, precompute data does not take it into account so the light bounced from the train is not rendered. That’s where Minecraft’s DirectX Raytracing update differs, however. With Unreal Engine’s extensive implementation, Unity, or even CRYENGINE’s GPU-agnostic fare, it won’t be long until ray tracing is par for the course. The areas where the question marks are remain black, however, they are supposed to be lit by indirect light, which is where Enlighten comes in. In this diagram you have a spotlight and a gray box. However, it is first bounce only and is noisy. The game looks fine, even as a modern release, but it’s only going to look better as hardware improves, just like the original, and plenty of the gameplay itself feels dated, and out of step with the quality of the visuals. You either add Enlighten's results at Screen Pixel or at the Gather Point. It creates high-precision results, but in the case of gloss reflections, multiple rays need to be transmitted, also in some case adding a second bounce might be required, all of which impacts the performance. Recently, Fortnite became the latest game to adopt Ray Tracing, a rendering technique resulting in realistic light rays. It’s not horrible, but it’s impossible to tell how the game could look once the software is actually working the way it should. Consoles, of course. During the initial precompute phase, Enlighten generates optimized runtime data about static actors (actors with a fixed shape and position). You can see how indirect lights are being updated. How Enlighten is addressing ray tracing in video games Sponsored article: ... Melbourne International Games Week 2020. The Turing architecture was the first to introduce AI and ray tracing accelerating right there in the hardware, catered to the wants and needs of Microsoft’s DirectX Raytracing. Our first topic is on ray tracing Reflection with Enlighten. Hardware Editor.
