A big step for the in-development open source NVIDIA Vulkan driver NVK, as Collabora have announced how it's hit Vulkan 1.0 conformance. Side-note: This is not coming from NVIDIA directly but people working on Mesa drivers.
What does this mean? As explained by developer Faith Ekstrand on the Collabora blog: "Practically, it means that we can pass the entire Vulkan conformance test suite. From the Khronos perspective, it means that NVK now meets the bar required to claim to support the Vulkan API officially. (There are some legal implications to this which matter to the Mesa project, but most users don't care about them.) From the perspective of users, it means the driver should pretty much work on Turing and later GPUs. There will still be bugs, of course, but those bugs are likely to be app-specific. Most stuff should just work."
This is after merging in their new back-end compiler which was required but there's still a lot of work ahead. As Ekstrand goes on to explain heading into 2024 they're actually not far off being able to advertise Vulkan 1.3 but they need to do plenty of compiler work to get there. Plus there's others working on getting Maxwell GPUs supported and once the compiler is a little more "feature-complete" they can then start "taking deep dives into apps, working on app-specific bug fixing as well as performance improvements".
Still experimental but it seems like open source NVIDIA drivers will get quite exciting through next year.
