Vulkan 1.4.331 Brings Two New Extensions

Written by Michael Larabel in Vulkan on 31 October 2025 at 05:48 AM EDT. 3 Comments
Just one week after Vulkan 1.4.330 brought five new extensions, Vulkan 1.4.331 is now available with another two new extensions for this high performance graphics and compute API.

Vulkan 1.4.331 has a handful of clarifications and other updates to the existing specification while adding two new vendor extensions:

VK_ARM_performance_counters_by_region - This new Arm extension allows capturing performance counters on a per region/tile basis. VK_ARM_performance_counters_by_region provides an enumeration of available counters and a means to request the ones to be captured on a per-render-pass instance.

VK_OHOS_external_memory - An external memory extension for use on Huawei's Open Harmony OS. The prior Vulkan spec update had introduced VK_OHOS_native_buffer for native buffer support on Open Harmony OS and is now complemented by external memory support as the Vulkan capabilities continue to be built out for this Chinese OS.

More details on Vulkan 1.4.331 via the GitHub commit.
