Ray Tracing Games - Full List
Ray Tracing technology or ray tracing, is a technology that has come to stay. Although initially it had limited support in games and a lot of criticism, it has been consolidated. Many video game developer studios even plan to implement it in future releases. So this NVIDIA bet for the world of video games that seemed short-lived, has ended up settling.
In this post we will explain a little what is this about Ray Tracing technology and the games that support it. Note that this rasterization technology may not be fully implemented in all games. Reflections, shadows, ambient occlusion or global lighting can be implemented.
NVIDIA and some developers use the term Ray Tracing. Microsoft in DirectX 12 it refers to raytracing. It can also be found on the net as ray traces O well real-time light ray tracing.

Origin of Ray Tracing
Although this technology may seem very new and invented by NVIDIA, nothing is further from the truth. Its initial proposal was made by Turner Whitted in 1980 and is based on an algorithm for determining visible surfaces written by Artur Appel in 1968 that was named Ray Casting.
Basically Ray Casting is an algorithm that calculates the amount of visible surfaces in a scene where you want to synthesize the ray traces from the observer's point. The calculation of the intersections of the rays with the objects of the scene is carried out and the intersection determines which are the objects visible to the observer.
Whereas ray tracing wants to determine the visible surfaces by adding the shading. Global lighting effects such as reflections, refractions, or cast shadows are taken into account here.
For reflection and refraction, you must have the material of the intersected object, since not all of them interact the same with light. While you stop the shadows, rays are thrown from an intersection point to the light source.
Robert Cook in 1985 improved the basic Ray Tracing algorithm to similar other effects in images based on stochastic sampling, relying on the Monte Carlo method. Effects such as moving blur, depth of field, or subsampling were added to remove saw teeth.[irp]
Photons of light
Depending on the roughness of the material and the spectra of light that it is capable of absorbing, we see one thing or another. Really, the only thing we see are photons of light after impacting on a material.
Let's take a very red and beautiful apple, worthy of display. We see it red because the apple absorbs the rest of the colors of the light spectrum. It only reflects the photons that are in the red color spectrum and for this reason we see it in that color. Something that happens with all colors and materials.
The light source emits in the entire chromatic spectrum, but the rays are absorbed and reflected by the elements of our environment. These photons of different wave light reach our retina and our brain interprets them.
This complex explanation is necessary, because one of the objectives of Ray Tracing is to achieve color realism. And it is that current games try to be as faithful to reality as possible, but it is very difficult. An approximation is achieved with ray tracing, but we are far from 100% fidelity.
And it is that the greatest complexity of this technology is that billions of rays interact every second on objects. Calculating the absorption, rebound, reflection, fusing together and even collision of them is very complicated. The computing power to achieve this is incalculable, but with the current ray tracing, a little more is advanced to achieve more realism in games.
Why hadn't this technique been used in video games before?
We have been left on the one hand that this technology is more than 40 years old and on the other hand that it depends on the interaction of light with objects.
This technique has really been used and for a long time, but not in video games. It was mainly used in the lighting of static scenes without movement, especially in architecture to show the lighting of a room. It was also used within movies and series for special effects and the like. This was due to the enormous complexity of this technology and the high computational cost. We must bear in mind that for 1 minute of video it could take hours or days to complete rendering.
So the reason for not being implemented in games was the amount of power required. An explosion in a movie could take days to render, which didn't matter. The problem is that in a game the rendering must be immediate and that is where the difficulty lies.
Games typically have a few quiet scenes, and the rest are often frantic. The 'quiet' scenes would not be a problem, but, can you imagine that you are fighting an enemy and it starts to jerk or takes minutes to render the scene? That would be crazy and more than one would destroy the screen in one hit.

Ray Tracing Operation
A modern video game relies on raster technology to display on screen. It allows generating 3D models with millions of triangles in two-dimensional textures that are shaped. The vertices of these triangles have associated position, color, texture, and orientation data.
Basically a 2D image is generated on the screen based on triangles and vertices that are interpreted in pixels. Each of these has associated color data. Finally, depending on the final scene, different color changes are applied according to the lighting of the environment.
Ray Tracing goes one step further and calculates the interaction of light with objects from the point of the observer. Furthermore, out of plane objects or the non-visible part of the objects are also taken into account. In the case of video game technology, a series of rays are launched and then by Artificial Intelligence the rest of the rays and their behavior in the scene are calculated.
And that's the great light ray tracing trick proposed by NVIDIA. Calculating all the rays and all the interactions would be crazy and truly impossible. That is why 'x' rays are launched in the scenes, to see their behavior. Using AI and Deep Learning extrapolations of the interaction of the rays with a limit of three refractions or reflections are carried out.[irp]
NVIDIA and Microsoft, pioneers
Its implementation in video games has only been possible thanks to NVIDIA and Microsoft. The first because it has added hardware to its GPUs for this technology. The second because it has implemented improvements in its graphical API to support this new form of rasterization.
To support Ray Tracing, it was necessary for NVIDIA to add RT Cores and Tensor Cores to GeForce GTX with Turing architecture. The RT Cores would basically perform the light ray tracing calculations. The problem is that these calculations cost up to 50% of the performance of a graphics card. We could go from playing 4K @ 60FPS to 4K @ 30FPS with Ray Tracing activated. For this, the Tensor Cores have been implemented, which are intended for Artificial Intelligence. What they do is help the RT Cores and 'simulate' ray traces or scene elements.
Microsoft for its part has released the DirectX 12 Raytracing API. This solution, which allows it to be more efficient for tracing light rays, would be like a support for the NVIDIA solution. It allows developers to use this technology in games in a much simpler and optimized way.
Currently, the graphics engines with full Ray Tracing support are: Ubisoft's Unreal Engine, Electronic Arts (EA) Frostbite, and Unity Technologies' Unity.
