Vulkan Ecosystem Tools

The repository contains the following Vulkan Tools:

These tools have binaries included within the Vulkan SDK.

VkTrace and VkReplay have been deprecated and replaced by gfxreconstruct. Both VkTrace and VkReplay have been removed from VulkanTools and can now be found in the vktrace archive. Both these tools are also no longer part of the Vulkan SDK.

git branch -m master main
git fetch origin
git branch -u origin/main main
git remote set-head origin -a

Updates to the LunarG-VulkanTools repository which correspond to a new Vulkan specification release are tagged using the following format: v<version> (e.g., v1.1.96).

Note: Marked version releases have undergone thorough testing but do not imply the same quality level as SDK tags. SDK tags follow the sdk-<version>.<patch> format (e.g., sdk-

This scheme was adopted following the 1.1.96 Vulkan specification release.
