In short, the technique dynamically identifies key objects in the frame, reducing the quality of those that are poorly visible (for example, are in the shadow or closed by other objects), and enhancing those that are vice versa in the player’s field of view.
All this is happening so quickly that the user does not notice such “magic” at all, but the introduction of this technology allows us to speed up the performance. For the first time, the technique was applied in Wolfenstein II: The New Colossus on the PC.
However, to implement VRS in its current form requires a modern NVIDIA video card based on Turing, which PS4 and Xbox One cannot boast of. Infinity Ward specialists are also introducing technology at the software level.

As an example of the implementation of the technology, Digital Foundry cited the forest map from the “Fire Contact” mode, where the “budget” of iron gives greater preference to the drawing of trees and the smaller one to the sky, where a more standard skybox is used.
According to the developers, the introduction of VRS can reduce the load from certain objects by 2-3 times, which, if implemented correctly, will give a completely stable frame rate, coupled with other technologies like dynamic resolution.
By the way, in March, Microsoft added support for VRS in the API DirectX 12.
