The Mesa 26.0 open-source graphics stack has been officially released, marking a significant update that enhances several graphics drivers with new features and improvements. A standout feature of this version is the improved raytracing performance for the RADV Vulkan driver optimized for AMD GPUs.<\/p>\n
Among the most notable additions is KosmicKrisp, a new Vulkan to Metal layered driver tailored for macOS environments. Users can also expect better GPU performance and reduced compile times as the RadeonSI driver now supports ACO by default.<\/p>\n
The RADV driver has also expanded its capabilities by incorporating new Vulkan extensions, which include VK_KHR_maintenance10, VK_EXT_shader_uniform_buffer_unsized_array, VK_VALVE_video_encode_rgb_conversion, and VK_EXT_custom_resolve. Similarly, the ANV Intel Vulkan driver has adopted VK_KHR_maintenance10 and VK_EXT_shader_uniform_buffer_unsized_array.<\/p>\n
Collabora’s NVK Vulkan driver for NVIDIA GPUs now supports several new Vulkan extensions, including VK_EXT_discard_rectangles, VK_KHR_maintenance10, and VK_EXT_shader_uniform_buffer_unsized_array. The same extent of support extends to Collabora’s PanVK graphics driver for ARM Mali GPUs, adding new functionality with extensions such as VK_EXT_external_memory_acquire_unmodified and VK_KHR_sampler_ycbcr_conversion.<\/p>\n
In addition to AMD and NVIDIA, the PowerVR Vulkan drivers have received updates to include VK_KHR_relaxed_block_layout and VK_KHR_dynamic_rendering among others. The release also includes broad support for Vulkan extension maintenance widely used throughout various drivers.<\/p>\n
