GeForce RTX 20-Series GPUs are powered by our advanced Turing architecture, which makes real-time ray tracing a reality. Furthermore, Turing is the first and only architecture to offer support for Variable Rate Shading, Mesh Shading, and other technologies that make games look and play better.
In Wolfenstein: Youngblood, we utilise Variable Rate Shading (VRS) and some NVIDIA magic to improve performance by up to 20%, with zero downsides.
In-game, you'll want to enable "NVIDIA Adaptive Shading" (NAS), our custom setting that combines the Content Adaptive Shading (CAS) and Motion Adaptive Shading (MAS) VRS techniques with some additional engineering. Together, they detect areas of the screen that don't require full-rate shading.
For instance, in a dark corner you can't see any detail, so why shade at maximum quality, or even shade at all? And if you or the camera are moving at speed, and perhaps with Motion Blur enabled, too, why shade detail at full quality when you won't be able to see it? Using this logic, we can shade individual pixels less frequently, with no perceptible reduction in quality, boosting performance 'for free'.
Using a debug option, we can demonstrate NVIDIA Adaptive Shading in a scene from Wolfenstein: Youngblood. Balanced, Quality and Performance presets adjust the amount of variable rate shading, and the extent to which affected areas are less frequently shaded, shown in our debug images in different colours. Blue means the shading rate is 2x lower, green 4x lower, and yellow 8x lower:
