Variable rate shadows will become a feature of Xbox One Series X, According to Major Nelson, And Digital Foundry has released a new video that explains exactly what VRS is and what it means for the next generation.
In the video, Digital Foundry accurately discusses what variable rate shadowing is and what it means for next-generation games and consoles, such as Xbox Series X.
So, what is variable rate shading? Basically, it affects the GPU's effort when rendering or shading certain areas of the frame. Basically, it can improve rendering performance and quality. Visually, it is possible to reduce the shadow rate “ with little or no reduction in the visible output quality & # 39; & # 39; so as to achieve “ free & # 39; & # 39; performance.
In the past, each pixel generated by the GPU meant a shadow indicating that it occurred by the pixel. This means that as long as the game is not enlarged to the output resolution, each pixel will be individually colored. Although this method is effective, it does not adapt well to ultra-high resolution screens.
As TVs jump from 1080p to 4k, this means users want their consoles and GPUs to keep up. Since this is not "reality", VRS does not "make the GPU bigger and denser", but "uses the resources of the GPU smartly" to make the density of higher resolution more feasible.
With variable rate coloring, developers no longer need to color each pixel individually. When using this technique, the shadows of these pixels will be rougher, so, for example, instead of coloring each 4k pixel in the sky, color each 2 × 2 or 4 × 4 block. This will also affect the performance when rendering the game, as you can see in the video when you turn off or turn on VRS in Gears Tactics and Wolfenstein: Youngblood.
Not only can VRS use it for pixel shading, it can also help speed up the game engine. In theory, it can also sparsely render game lighting for game engines that use delayed lighting.
Of course, here, "Variable Rate Shadow" has many other features, so you need to watch the video to learn more.
This is a very skillful video, but for a small group of us who are not skilled, VRS explains it well.
The Xbox Series X holiday is over. So far, we have provided all other information about the next-generation console.
