PIX 1903.26 – Occupancy for Turing GPUs and Variable Rate Shading
AvatarMarch 27, 2019Mar 27, 201903/27/19

Today we released PIX-1903.26, available for download here. This release includes support for Variable Rate Shading in GPU Captures, and it adds support for Occupancy on NVIDIA Turing GPUs such as an RTX 2080.
 
Variable Rate Shading
Variable Rate Shading (VRS) is a powerful new DirectX 12 feature that allows applications to significantly reduce their pixel shading work in exchange for minimal loss of visual fidelity.
