VK_EXT_mutable_descriptor_type missing from Vulkan Beta driver 515.49.18 onward

The changelog for Vulkan Beta driver 515.49.18 says it adds VK_EXT_mutable_descriptor_type but it does not appear to be included according to vulkaninfo. Just tried the newly released 515.49.19 driver as well and it’s still not there. All other changes listed in the changelog for both driver versions are present. Any idea why?

It is only available on Turing and newer.

I don’t know what is the technical reason for this but if you are purely interested in that because of vkd3d-proton performance/reliability standpoint Nvidia seems to be abandoned Pascal on that front.

Either get AMD or Ampere.

Thanks for exploring and confirming @VulkanGuy . Had the impression Pascal being dropped but couldn’t put my finger on it.
