NVIDIA on Tuesday released the 455.26.02 Linux driver (and 457.00 version for Windows) that adds this fragment shading rate extension. Additionally, VK_KHR_shader_terminate_invocation was also added as the other new extension of Vulkan 1.2.158. This second extension allows terminating a shader invocation immediately and setting the coverage of shaded examples to zero.
The updated NVIDIA Vulkan beta drivers for Windows and Linux with this support can be found via developer.nvidia.com .
