NVIDIA has released its 615.71.09 Linux driver, bringing several Vulkan improvements. A notable feature is the support for VK_NV_low_latency revision 2, which enables out-of-the-box Proton integration for NVIDIA Reflex in Vulkan-native games. This update also fixes a bug where VK_NV_low_latency2 did not reduce latency on swapchains created from VK_KHR_wayland_surface and VK_KHR_display surfaces. Further enhancements include resolutions for multiple startup and alt-tab hangs when NVIDIA Smooth Motion was active. The driver also addresses a file descriptor leak that occurred when the Vulkan loader unloaded libGLX_nvidia.so.0 following a vkDestroyInstance call. Additionally, the release adds support for the VK_EXT_cluster_acceleration_structure Vulkan extension.
