NVIDIA released a new 440.66.15 Vulkan Beta Driver

By - | Views: 11,539

NVIDIA continue advancing their Vulkan drivers with a brand new Beta now available that pulls in a good bunch of fixes. This is driver version 440.66.15, released May 26.

Changelog for Linux:

  • Fixed 16-bit SMin/SMax
  • CPU performance improvements for VkFence creation and usage
  • Fixed a bug where vkUpdateDescriptorSetWithTemplate would ignore the stride parameter for some VkDescriptorType values
  • Fixed layout of compute shader shared memory that may have resulted in a compiler crash
  • Fixed a bug where vkCreateSampler would fail with no borderColor data, even though it wasn't needed
  • Fixed a compiler issue processing image operation with extra unused coordinate operand components
  • Fixed writing to dynamically indexed vec2 and vec3 fragment color outputs

While the majority is bug fixing, it's nice to see a performance improvement make it in too!

Reminder: you know it's a special Beta driver thanks to the additional two numbers on the end of the version string, with the newest stable version of the NVIDIA driver for Linux at 440.82 which released on April 7. This special Vulkan beta driver is where all the shiny new stuff goes in before making its way into the stable release for everyone. Really, it's mostly aimed at developers and serious enthusiasts. Unless you need what's in them, it's generally best to wait for the stable drivers.

I wonder why the beta drivers stopped going into popular distribution third-party repositories. It would be nice to properly test it (with proper package management) specially with the new features of wine 5.9+.

Nice. Nvidia seems to be on fire with the vulkan beta drivers lately. Installed, but haven't tested much yet. Seems to work fine but no idea if i got some more perf somewhere. probably not a big thing anyway.

Mm, heat sinks not good enough, huh? Pity.
