It's been a while since last looking at the Zink performance for this OpenGL implementation built atop the Vulkan APIs, but with all of the Zink progress by Valve's Mike Blumenkrantz and others, here is a fresh round of testing.
Intel's ANV open-source Vulkan driver has increased its instruction heap size to 2Gb in order to address a hang experienced with the game Overwatch while this is also likely to help other software/games moving forward.
While Linux 6.2 supports Arc Graphics out-of-the-box and Mesa 23.1 has good OpenGL/Vulkan support, for those running Linux distributions on older kernels and Mesa packages there is less than ideal support either no support at all or having to resort to force-enabling the DG2/Alchemist support and potentially running on older OpenGL/Vulkan drivers with various problems
While we are still waiting for the Intel Xe kernel driver to be upstreamed as the modern alternative to the long-used i915 Direct Rendering Manager (DRM) driver, upstream Mesa Git is nearly ready in supporting the Xe kernel driver and its new/changed interfaces.
