The second update in the space of a week, NVIDIA just today put out another NVIDIA Vulkan Beta driver which further expands the Ray Tracing capabilities on Linux.
Wonderful to see NVIDIA continue pushing Linux forward, after the 440.66.07 driver release yesterday which helped DOOM Eternal through Steam Play Proton and added in thread-capable deferred ray tracing pipeline creation amongst other things we have the 440.66.08 driver out now with these changes and improvements:
So what are Ray Queries exactly? According to the official spec, "Ray queries can be used to perform ray traversal and get a result back in any shader stage. Other than requiring acceleration structures, ray queries are performed using only a set of new shader instructions.". More info in the links above.
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 440.64 which released on February 28. This special Vulkan developer beta driver is where all the shiny new stuff goes in before making its way into the stable release for everyone.
