With each new console generation—accompanied today by handheld consoles, computers, and smartphones — cutting-edge technologies emerge and are renewed to make experiences created in the video game industry even more realistic and immersive. It is the case of Ray Tracing. 76q5e
Those who enjoy games are becoming increasingly demanding in of performance and graphics, and companies are putting their gears in full swing to deliver results on increasingly powerful hardware. One of the pioneers in dedicated gaming graphics cards is the NVIDIA, and it is also her turn to be a pioneer in this type of resource. Let's find out a little about this ambitious technology.
What is Ray Tracing? 6p6a54
O Ray Tracing is a technology of the video card series GeForceRTX, which promises to revolutionize the market and retire, over the years, the 1000 series cards. It is a graphic processing resource related to lighting in the environments and game elements differently from what we are used to, improving graphic aspects such as shadows , reflections, ambient occlusion, among others. This happens by projecting rays onto objects instead of using the standard lighting of the game engines current.
The technique consists, first, of an algorithm capable of producing the so-called BVH (bounding volume hierarchy), a type of data structure capable of real-time ray tracing. After calculating the interaction between the beam and the object of the scene in question, it is decided what processing should be done — the ray can be reflected, terminated or even interact with other elements of the scene during its path.
In a second moment, after mapping all the interactions that occurred (path tracing), a kind of granular image is formed, pointing out features such as depth and color. This processing through advanced Artificial Intelligence, known as noise reduction (denoising), reliably transforms this set of points into a frame (image) of the scene.
We must that all this takes place in real time, so the entire setup of the gaming PC in question must be up to date with the minimum requirements.
Advantages and disadvantages 4s6a3p
The result of post-processing effects, given the availability of the boards GeForceRTX e hardware compatible, is very impressive. for the case of ambient occlusion (ambient occlusion), shading present in areas of high lighting contrast, we can see that the result happens mainly in the more subtle look of the dimming, with a more realistic sense of depth.
With respect to Shadows (shadows), the ray projection technique makes it possible to identify when an object is preventing the arrival of this beam to its final destination. Through intercepts on the surface of the object and mathematical approximations, it is possible to identify what it is and how the object behaves in the face of light sources in a detailed and precise way.
Os reflexes with Ray tracing are among the greatest advantages of contemporary computer graphics. Until recently, achieving levels of quality was only possible through shaders programmables — which did not always fulfill the role satisfactorily due to the high demand for processing. The result can be noticed on brighter or more opaque surfaces, with more or less light beams being redirected and projected towards the in the form of a pixels.
Among the disadvantages are the prices, which range from US$500 to over US$2500 depending on the models. Some manufacturers offer options with water-cooling (water cooling), which further increases the values. There are also cheaper alternatives depending on the automaker, but the prices orbit around the values stipulated by the NVIDIA.
Recently, the NVIDIA launched a new line of video cards that brings the technology Ray tracing as the main differentiator. At GeForce RTX SUPER 2060, 2070 and 2080, are direct evolutions of the standard versions of the same name, and come with 8 GB of GDDR6 RAM, up to 15.5Gbps of memory speed, and clock boost above 1.800MHz.
Regarding prices, the RTX 2060 SUPER, a model with more basic configurations, arrived on July 9 with a price starting at US$ 399. RTX 2070 e 2080 SUPER, will cost $499 and $699, respectively. THE NVIDIA offers a package for those who take the new video cards of the line RTX-SUPER, including games Wolfeinstein: Youngblood e Control.

Games with ray tracing 39q5v
With the recent announcement of the general specs of the next console in the family PlayStation and the subsequent trailer revealing the Project Xbox Scorpio, we know that the powerful machines to come will Ray Tracing. Even in 2019, some games from large companies already have this type of to make the experience even more realistic.
Among the Launched games compatible with ray tracingwe have Shadow of the Tomb Raider, Metro Exodus, Battlefield V, Assetto Corsa , Quake II RTX and the early access version of stay in the light. About games not yet released, the most relevant is Wolfeinstein: Youngblood.
We can only wait for more announcements of titles that the technology discussed in the article — so keep an eye on Showmetech for all the latest on games and technology.
