UL Benchmarks announced yesterday to have added a new Variable Rate Shading (VRS) test to its 3DMark suite of benchmarks. This test, released as a free update if you've got 3DMark Advanced Edition, focuses on Tier 2 Variable Rate Shading, which is currently only available on NVIDIA Turing GPUs.

With Variable-Rate Shading, a single pixel shader operation can be applied to a block of pixels, for example shading a 4×4 block of pixels with one operation rather than 16 separate operations.
