While there has been significant progress in game lighting, the real value of ray tracing comes from its environmental interactions rather than the light itself.
The Graphics Revolution in Gaming
Ray tracing allows for the creation of reflections, shadows, translucence, and dispersion that are incredibly lifelike. Taking into account the light’s source and computing the interaction and interplay, the programme handles shadows, reflections, and light in a manner similar to the human visual system. The way light reflects off of nearby objects also affects the colours you see. PossiblyEthereal: Exploring the Mysterious Borderland Between Fact and Fiction
With a powerful enough computer, it is possible to make computer-generated visuals that are nearly indistinguishable from the real thing. The catch is that graphics processing unit (GPU) power is limited, even on top-tier gaming PCs and contemporary game consoles. The availability of enormous processing resources in the cloud is the lynchpin upon which film and television studios rely when creating computer-generated imagery (CGI) using ray tracing. It can still be a tedious process, even after that. Current gaming hardware isn’t up to the task of doing it in real time. Read more
For the most part, rasterization is now what you’ll see in video games. Rendering computer graphics using this method is quicker. Shaders are necessary for rasterization to accurately depict lighting, but it flattens 3D scenes into 2D pixels for viewing. Until it becomes feasible to completely ray trace lighting engines in games, rasterization will be necessary in most games, even if real-time ray tracing is becoming more frequent in PC games because to the specialised technology in recent Nvidia graphics cards.
So, although the results so far may not be spectacular, the groundwork is being laid for some really spectacular outcomes in the future. The graphics of personal computer ray tracing games might be about to undergo a revolution. Guia Silent Hill Geekzilla A Survival Horror Guide
Forever Gone Are Any Textures Or Shades
A common technique in traditional computer graphics, rasterization reduces three-dimensional rendering to a two-dimensional preview. Rasterized images employ complex shaders to mimic the effect of depth perception. Without a shader, ray-traced visuals inherently integrate depth. Read also

Since ray tracing technology has been around for some time, you have probably seen ray-traced visuals before. Hollywood uses ray tracing to make computer-generated special effects look identical to live-action. Currently, ray-traced images are exclusively seen in pre-rendered sequences because their execution would take a typical render farm days—if not weeks—of processing power ray tracing.

For the past decade or more, Nvidia has pushed for the widespread use of ray-tracing algorithms. After purchasing RayScale in 2008, NVIDIA made history at Siggraph 2010 by showcasing interactive ray tracing on Quadro cards based on Fermi technology. Given our hands-on experience with the demo, we made an educated guess that real-time ray-tracing will be achievable “in a few GPU generations.”The new Quadro RTX series from Nvidia is the culmination of six years of research and development into real-time ray tracing. Following the launch of the professional-oriented Quadro RTX GPU series, the consumer-oriented GeForce RTX 20 Series introduced real-time ray tracing technology to the gaming community. These were enhanced in the 2020 GeForce RTX 30 Series (Ampere) GPU release. Also, older GPUs based on Pascal, such as the GeForce GTX 1650 Ti, can enable software-based ray tracing, although at a slower rate.
Having said that, ray tracing capabilities in hardware aren’t exclusive to Nvidia. Begins to work with AMD’s newest Radeon RX 6000 series (RDNA 2) GPUs. Similarly, hardware ray tracing is built in into Intel’s new Arc series of desktop and laptop GPUs.
