Mesa's Vulkan windowing system integration (WSI) code for Wayland has added the 'IMMEDIATE' present mode option that uses Wayland's tearing-control unstable extension to allow for images to be presented immediately but at the risk of visible screen tearing.

Just days after covering a recent ~10% speed-up for the Intel Arc Graphics on Linux, another optimization has landed in Mesa 23.3-devel for further enhancing Intel's latest graphics wares with their open-source driver stack. The latest performance boost for Intel graphics on Linux is by supporting the I915_FORMAT_MOD_4_TILED_DG2_RC_CCS modifier.

Merged to Mesa 23.2-devel recently was an Intel Arc Graphics driver change to improve performance.

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.
