NVIDIA have just recently released two new drivers for Linux users, with the main series now being at 430.09 adding new GPU support and the Vulkan beta driver 418.52.05 giving ray-tracing to some older GPUs.
Firstly, the Vulkan beta driver 418.52.05 was actually released last week, which adds support for the "VK_NV_ray_tracing" extension for certain older graphics cards including the TITAN Xp, TITAN X, 1080, 1070, 1060, TITAN V and 1660 (along with Ti models). It also adds support for the "VK_NV_coverage_reduction_mode" extension, which doesn't seem to have any documentation up just yet. They also cited "minor performance improvements" and two bug fixes.
Additionally, just today NVIDIA also put out the mainline 430.09 driver to add support for the recently launched 1650 and 1660 models.
This driver also now has HEVC YUV 4:4:4 decode support to the NVIDIA VDPAU driver, along with support for creation of YUV 4:4:4 video surfaces in the NVIDIA VDPAU driver. On top of that this driver also now supports the GL_NV_vdpau_interop2 OpenGL extension, the nvidia installer has better support for openSUSE Leap 15 and SUSE Linux Enterprise 15 and they also upped the minimum supported X.Org xserver version to 1.7.
There's more, so do see the 430.09 release notes here.
