Mesa 22.0 is set to launch this week, ushering in increasing processing on Intel Arc Alchemist DG2 GPUs which are set for the Q1 2022 launch. Originally planned for a February release, Intel assisted in initiating their Xe HP pipeline optimization as quickly as possible so that users would not have to wait longer for compatibility.

Mesa 22.0 will help provide pixel pipeline optimizations, increasing the OpenGL and Vulkan performance for the Intel discrete GPUs between 20 to 40%. This includes not only standard tasks but heavy workloads, such as Unigine Valley, which shows that there was a 40% increase while utilizing Intel DG2-448 hardware. Other titles, like DOTA 2, showed a boost of 30% and Xonotic increased by as much as 14%, allowing for more performance produced in a more efficient process.
