The reduction was discovered after a thorough review using VKOverhead, a micro-benchmarking tool designed by Mike Blumenkrantz when he was working on his other project at the time; the Zink and Vulkan optimizations. Additionally, Lionel Landwerlin, an Intel engineer, was coding the ANV drivers to assist with the Vulkan driver CPU overhead issue. Using the VKOverhead tool, he found an increase of thirty percent compared to the primary performance initially discovered but has yet to repeat the same results in further testing. A note from Landerwerlin to Blumenkrantz on the GitLab merge request reads: However, these are the code changes made in the recent merge request: It previously made a change for me with a good improvement (I have written down 30%). But maybe that was in a debug build. Or it could be an issue with my setup (primary GPU AMD with display, secondary with Intel IGPU). The Mesa Project continues to be a collection of various APIs to assist with graphical support in an open-source environment. Since its humble beginnings in August of 1993, it has strengthened over the years to be integrated with many graphics engines across several platforms. Such implementations like OpenGL and Vulkan see support from major companies like Intel, AMD, NVIDIA, and more. It sees constant updates on a monthly average and updates the community frequently of any significant or minor changes. descriptor_template_1ubo_push: 40670 / 85786 **descriptor_template_12ubo_push: 4050 / 13820 **descriptor_template_1combined_sampler_push, 34410 / 34043descriptor_template_16combined_sampler_push, 2746 / 2711descriptor_template_1sampled_image_push, 34765 / 34089descriptor_template_16sampled_image_push, 2794 / 2649descriptor_template_1texelbuffer_push, 108537 / 111342descriptor_template_16texelbuffer_push, 20619 / 20166descriptor_template_1ssbo_push, 41506 / 85976 **descriptor_template_8ssbo_push, 6036 / 18703 **descriptor_template_1image_push, 88932 / 89610descriptor_template_16image_push, 20937 / 20959descriptor_template_1imagebuffer_push, 108407 / 113240descriptor_template_16imagebuffer_push, 32661 / 34651 Larabel states that 720 lines of new code have been completed, and over 220 codes have been deleted from the Mesa3D’s Vulkan driver.
