With enough computational power available, it's possible to produce incredibly realistic CG images that are nearly indistinguishable from real life. In games, this Ambient Occlusion (AO) is key to grounding objects and the smallest details. However, thanks to Nvidia’s DXR Spotlight contest, Now that ray tracing is the hot new technology behind the biggest PC games, we thought it was about time to dive into exactly what it is, how to do it, and the best ray tracing games. Animation studios like Pixar have been working with ray traced effects for years. The algorithm takes into account where the light hits and calculates the interaction and interplay much like the human eye would process real light, shadows, and reflections, for example. Real-Time Ray Tracing is the biggest leap in computer graphics in years, bringing realistic lighting, shadows and effects to games, enhancing image quality, gameplay and immersion. Reflection occurs when photons bounce off a surface. Instead, the GPU “cheats” by using several smart approximations to deliver something close to the same visual effect, but without being quite as taxing on the hardware. Piece all the footage together and you have a flowing story.Unfortunately, we still don’t have consumer-level PCs that can truly render ray-traced graphics at high framerates. It’s not clear whether it will work in the same way as Nvidia’s RT cores, or will be designed to offer ray tracing to a wider array of games, but the support will be there.Hardware-accelerated ray tracing will be available in the Xbox Series X and PlayStation 5 this holiday season. In 2019, the only graphics cards that support real time ray tracing come from Nvidia. And, if the Now, admittedly that’s not a lot of games that showcase Nvidia’s premiere technology, but don’t worry – there are plenty of other games that will soon use ray tracing. In 3D computer graphics, ray tracing is a rendering technique for generating an image by tracing the path of light as pixels in an image plane and simulating the effects of its encounters with virtual objects. Real-time ray tracing for Windows 10 pushes Minecraft’s graphical boundaries even more! For instance, in Metro Exodus at 3,440 x 1,440 with the ‘Extreme’ preset we get around 41 fps with an Nvidia GeForce RTX 2080 Ti, however, once we enable ray tracing with the Ultra setting, performance plummets, averaging around 23 fps. It converts the 3D graphics into 2D pixels to display on your screen, but rasterization requires shaders to depict realistic lighting. We've seen in-game lighting effects become more and more realistic over the years, but the benefits of ray tracing are less about the light itself and more about how it interacts with the world. Ray-Traced Ambient Occlusion: Where objects or surfaces meet, light is occluded, creating subtle shadows.

Like any movie or TV show, scenes in CGI animation are typically “shot” using different angles. This is a speedier way to render computer graphics. AMD has said that it wants to tackle ray tracing at some point in the future, and while it will technically work on AMD graphics cards, it will turn any game you enable it in into a veritable slideshow.
New York, Developers place light sources within an environment that emit light evenly across any given view. For each frame, you can move a camera to capture the action, zoom in, zoom out, or pan an entire area. The most fully featured implementations of ray tracing can still be found in the earliest of RTX demo games, like Battlefield V, Shadow of the Tomb Raider, and Metro Exodus, though newer games like Control and MechWarrior 5: Mercenaries look great too. Developers can only fake it through careful, controlled use of preset, static light sources. Photons have no real size or shape — they can only be created or destroyed.That said, light could be identified as a stream of photons. Placing all these “stage lights” takes Some games go the whole hog and use ray tracing for global illumination, effectively ray-tracing an entire scene. Ray tracing allows for dramatically more lifelike shadows and reflections, along with much-improved translucence and scattering. 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 objects.
This makes ray tracing best suited for applications where taking a relatively long time to render can be tolerated, such as in still computer-generated images, and … It’s not uncommon to see massive frame drops when enabling these effects. Right now, there are only 5 games that use Nvidia ray tracing tech, and only a few big name AAA titles. Achieving that look without ray tracing is extraordinarily hard. Either way, we’re sure many more developers are willing to jump on the ray-traced bandwagon, and we’ll update this page just as soon as we hear of any others. Surface textures can reflect light to mimic shininess, but only light emitted from a static source.Overall, the GPU’s evolution has helped this process become more realistic in appearance over the years, but games still aren’t photorealistic in terms of real-world reflections, refractions, and general illumination.
