The Vulkan EXT_present_timing was in development for years to [1]help avoid game stuttering and [2]released this past November with Vulkan 1.4.335 . This significant extension as of today has been wired up in Mesa 26.1-devel for the key Vulkan drivers and working on both X11 and Wayland.

VK_EXT_present_timing allows apps/games using Vulkan swapchains to obtain information on the presentation engine's display for accurate timing information and to assist in scheduling a present to happen no earlier than a desired time. With VK_EXT_present_timing you can help avoid game stuttering and overall a big improvement for game engines opting to use this functionality.

The Mesa support for VK_EXT_present_timing support has been worked on by Valve developers and other stakeholders. Since December [3]the code was considered feature complete while today it was finally merged to Mesa Git.

Hans-Kristian Arntzen of Valve's Linux team and known for his work on VKD3D-Proton led the work on EXT_present_timing for Mesa.

The 19 patches for implementing Vulkan present timing support have it working on both X11 and Wayland windowing system integration. Mesa Vulkan drivers where EXT_present_timing is wired up include Intel ANV, Radeon RADV, Arm Mali PanVK, NVIDIA NVK, and Qualcom Adreno TURNIP.

The code is [4]merged as what's another big boost for Linux gaming for those using these Mesa Vulkan drivers.
