A few days ago we told you about the new technology “Adaptive Shading” from Nvidia and its RTX graphics cards. That is specifically designed for improving the performance of stage shading. At the time, we were asking ourselves that how much performance yields would comes to games by using Nvidia Adaptive Shading? The answer came quickly.
This feature is one of the strengths of Turing’s architecture, that allows the 20 RTX GPU Series to actively reduce shading in games, with a negligible impact on the resulting final image quality. According to Guru3D site tests, the performance gain is 5%.
Wolfenstein II is the first title to take full advantage of the functionality of the Turing architecture, and the first tests conducted by Guru3D shows a performance of +5% in the game, in which the Adaptive Shading was enabled in 4K and 1440p ultra resolutions. This doesn’t seem to have a high impact on performance, but “still it is on the positive side”.
Note that Nvidia Adaptive Shading has three presets that affect performance: quality, balance and performance.
The technology is unique to RTX graphics cards
NAS is just one of the shading techniques within Turing’s architecture under the umbrella of Variable Rate Shading. While Content Adaptive Shading focuses on flat color areas, there is also Motion Adaptive Shading and Foveated Rendering. The first reduces the shading effect of fast moving objects, and the second adjusts the shading rates based on user orientation and uses the limits of the human eye to reduce the workload of the GPU.
