It allows you to dynamically load entrypoints required to use Vulkan without linking to vulkan-1.dll or statically linking Vulkan loader. Additionally, volk simplifies the use of Vulkan extensions by automatically loading all associated entrypoints. Finally, volk enables loading Vulkan entrypoints directly from the driver which can increase performance by skipping loader dispatch overhead.

volk is written in C89 and supports Windows, Linux, Android and macOS (via MoltenVK).
