VK_KHR_ray_tracing extension not found with beta Vulkan driver

I have a RTX 2060 mobile and I’ve installed the latest 457.44 beta drivers for Vulkan. However, my programs are unable to find the VK_KHR_ray_tracing device extension, and it’s also not shown in Vulkan configurator. According to the driver page the beta driver is supposed to support this extension for my card - is this a bug? If it is, is there a way I can work around it (like downloading an older version of the beta driver)? Thanks.

The VK_KHR_ray_tracing extension was the provisional Khronos ray tracing extension and was replaced with a few different extensions including VK_KHR_ray_tracing_pipeline when the ray tracing specification was finalized. If you are implementing a ray tracing application I would recommend reading up on the details of the finalized specification: https://www.khronos.org/blog/vulkan-ray-tracing-final-specification-release

If you want to run legacy applications that were implemented with VK_KHR_ray_tracing then I had success with driver version 456.80 (You will have to find this through a 3rd party download).
