NVIDIA just quietly released another fresh update to their special developer-focused Vulkan Beta Driver.
After moving it over to the 455 series at the end of September, they released driver version 455.26.01 on October 9 which is a small bug-fix cleanup with these changes:
- Reduce host memory consumption for descriptor memory when VkDescriptorSetVariableDescriptorCountAllocateInfo is used
- Handle SPIR-V 1.4 non-Input/Ouput entry point variables correctly
- Fixed a blending optimization that sometimes produced an incorrect result
- Fixed SPIR-V intersection shader compilation issue when multi entry point ray tracing modules are used
Reminder: 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 use the stable drivers.
The newest stable versions of the main NVIDIA driver for Linux are at 450.80.02 released on September 30 from their "long lived" series or 455.28 released on October 7 from their "short lived" series. The difference can be a little confusing, NVIDIA explained the difference between short / long lived drivers as:
Any given release branch is either long-lived or short-lived. The difference is in how long the branch is maintained and how many releases are made from each branch. A short-lived branch typically has only one or two (non-beta) releases, while long-lived branches will have several.
When we make changes to the driver, we evaluate the oldest branch the change needs to go into. New features go into whatever the latest branch is, while bug fixes go into the older branches and are integrated through the newer branches. So using a short-lived branch doesn’t mean that you miss out on fixes, it just means that you also get the latest features.
