The latest effort for this Rust-based OpenCL driver that works across Gallium3D drivers is around better hardware utilization.<\/p>\n<p>Herbst has improved the workgroup size selection for Rusticl for coming up with the best block size. He noted in the merge request that this change should &#8220;[increase] hardware utilization by a significant amount&#8221; by better filling workgroups and subgroups. In turn this should improve performance for applications requesting arbitrary global sizes. No real-world workload performance numbers were shared as part of this merge request, but on a fill rate basis there is indeed a huge improvement at least for better GPU utilization:&#13;<\/p>\n<p align=\"center\"><img decoding=\"async\" src=\"https:\/\/www.newsbeep.com\/il\/wp-content\/uploads\/2026\/07\/1782989354_517_image.webp\" alt=\"Rusticl benchmark comparison\"\/><\/p>\n<p>Those making use of the Rusticl OpenCL driver and wanting to learn all the details on this improvement can see <a href=\"https:\/\/gitlab.freedesktop.org\/mesa\/mesa\/-\/merge_requests\/42288\" rel=\"nofollow noopener\" target=\"_blank\">this Mesa merge request<\/a>.
